What are genes made up of?Genes are made of DNA and code for proteins.This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.
Therefore, Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.

What do individuals who are heterozygous for codominant traits show for a
phenotype?
Answer:
Individuals who are heterozygous for co-dominant traits show in their phenotype both traits, without mixing.
Explanation:
Codominance is a type of inheritance that does not follow the rules of Mendelian inheritance, characterized by the absence of recessive traits and two different alleles for a character that behave as dominant.
Heterozygous individuals can be observed in codominance that show two different characteristics in their phenotype, without mixing, such as cattle with spotted skin or two colored flowers.
Bison in Yellowstone National Park have a food-limited carrying capacity that determines how their population grows. If the population grows too large, some bison will either starve or migrate to search for more food. The park is able to support a maximum population of 4,500 bison. Park conservation officials must watch the population and prevent the bison from overpopulating, since they would migrate to nearby farms, causing agricultural damage and creating hazards to drivers. The bison begin to migrate when the population reaches 4,000 because of competition for food. If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population size after one year and determine whether the park will need to take measures to control the population.
A. The population will be 3,845 after a year. The bison will not pose a problem until the following year, and no conservation action will need to take place.
B. The population will be 4,675 after a year. Some bison will need to be removed to prevent migration, since they will surpass the resource availability.
C. The population will be 1,023 after a year, since the growth rate is too low. Conservation efforts will need to focus on increasing the bison population.
D. The population will be 4,500 after a year. The bison cannot exceed the carrying capacity, so they will stop reproducing. Some bison will need to be removed.
Answer:
A. The population will be 3,845 after a year. The bison will not pose a problem until the following year, and no conservation action will need to take place.
Explanation:
The exposed example refers to a population that exhibits a logistic growth model, Where the principal limiting factor is food availability
N is the total size of the populationNt the population size after a T timeK the carrying capacityr the population growth rate per capitaWhen N < K the population has not reached the maximum size that can be supported by the environment. It can increase in size.
When N = K the population has reached the maximum size that can be supported by the environment. It can not grow anymore. The population reached a maximum point delimited by available resources, such as food
When N > K the population has supered the maximum size that can be supported by the environment. It must decrease in size. because there are not enough resources.
To calculate the population size after one year, we need to use the following equation.
N t+1= Nt+rN(1-N/K)
Available data:
K = 4500
N = 3652
r = 0.28
Nm= 4000
N/K = 3652/4500 = 0.8115
r.N = 0.28 x 3652 = 1022.56
N t+1= Nt+rN(1-N/K)
N t+1= 3652+1022.56(1-0.8115)
N t+1= 3652+1022.56(0.1885)
N t+1= 3652+192.753
N t+1= 3844.75

Which statement is true regarding the transmission of sex-linked traits in a population?
O Males cannot carry recessive alleles for sex-linked traits.
O Males cannot express dominant alleles on the X chromosome.
O Males cannot express recessive alleles on the X chromosome.
O Males cannot pass alleles for sex-linked traits to their daughters.
Answer: none of the statements are true
Explanation: Males can have a recessive copy of a X-linked gene, and can pass that on in the X containing gamete and so pass it on to daughters, but not to male offspring. Males will express whichever allele, dominant or recessive that they carry.

What is your opinion on the use of stem cells, obtained from fertilized eggs or early stage embryos
USE OF STEM CELL:
The first attempts to turn mature cells back into pluripotent stem cells involved a process called cloning. In the cloning process, an egg is fertilized in the lab, and right after fertilization, the DNA is removed from the egg.These stem cells come from embryos that are three to five days old. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.Despite the potential benefit of using human ES cells in the treatment of disease, their use remains controversial because of their derivation from early embryos.Learn more:

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M

October 1, 2017 marks 27 years since the beginning of the Human Genome
Project. The goal of the group was to map the entire 3 billions bases and
80,000 genes in the human genome. On April 14, 2003, it was announced
that the goal was accomplished. Using this information, scientists have been
able to predict the risk of genetic diseases and understand the process of
inheritance. Which of the following statements best describes the process of
using the genetic code to produce polypeptides (proteins)?
Translation is used to produce a strand of RNA and proteins from a single strand of DNA.
O RNA produces a strand of DNA through transcription, then the DNA builds a protein molecule
through translation
O A single strand of DNA is used to make mRNA using translation, then the mRNA provides the
template for producing a protein through transcription
O A single strand of DNA is used to produce mRNA through transcription, then translation provides
the code for bonding amino acids to make a protein.
Answer:
The last one. A single strand of DNA is used to produce mRNA through transcription, then translation provides the code for bonding amino acids to make a protein.
Explanation:
Educated guess, but also. Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins.
A scientists observes several fossils in a river bed. Based on these observations, she concludes that invertebrates once dominated that ecosystem. This is an example of inductive reasoning.
True
False
Answer:
False
Explanation:
It is false because inductive reasoning is a reasoning that is not based on observations but it is based on hear say,i.e what people say, what is read or news read e.t.. Therefore it is not observed. But the above us deductive reasoning because this is based on observations, theories e.t.c. it is based on what is seen or observed.
Answer:
True
Explanation:
Inductive reasoning is a method of reasoning in which conclusion are drawn on the premise of the evidence supplied. The evidence are the tools from which conclusions are drawn but not full assurance, of the truth of the conclusion.
It could also involve the individual's experiences and observations together with what are learned from others, this together help synthesize the general truth.
The fossil serves as evidence on which the scientist based her conclusions.
In eukaryotes, general transcription factors A) are required for the expression of specific protein-encoding genes. B) bind to other proteins or to a sequence element within the promoter called the TATA box. C) inhibit RNA polymerase binding to the promoter and begin transcribing. D) bind to sequences just after the start site of transcription.
Answer:
B
Explanation:
The general transcription factors bind to other proteins or to a sequence element within the promoter region known as the TATA box.
Transcription is a biological process involving the synthesis of RNA from a DNA template. The process of transcription begins with the binding of an enzyme, the RNA polymerase, to the promoter region of a gene. Prior to that, however, a group of enzymes known as the transcription factors must bind to a specific sequence within the promoter region - the TATA box. The binding of the RNA polymerase signals the unwinding of the section of the DNA to complete the initiation complex.
The correct option is, therefore, B.
