A human gene was initially identified as having three exons and two introns. The exons are 456, 224, and 524 bp, whereas the introns are 2.3 kb and 4.6 kb.
Required:
a. Draw this gene, showing the promoter, introns, exons, and transcription start and stop sites.
b. Surprisingly, this gene is found to encode not one but two mRNAs that have only 224 nucleotides in common. The original mRNA is 1204 nucleotides, and the new mRNA is 2524 nucleotides. Use your drawing to show how this one region of DNA can encode these two transcripts.
Once a standard curve has been prepared by plotting numbers of bacteria (CFU/mL) versus absorbance for one species of bacteria, this curve can be used for estimating bacterial numbers by measuring absorbance for any species of bacteria.
a. True
b. False
Answer:
b. False
Explanation:
The biomechanism of bacterial growth may be examined, by graphing cell growth (also known as absorbance) vs incubation time of the bacteria. A standard growth curve is the result of this process. The amount of turbidity in the broth culture is proportional to the number of microorganisms present.
A standard curve produced for a particular species can't be utilized to predict the number of bacterial counts for a different species due to the listed factors.
The rate of bacterial cell reproduction varies from a particular species to another.Varying species have different absorbance thresholds.discuss the ecological importance of the dark phase
Answer:
In the dark phase (which takes place in the stroma), the ribulose bisphosphate added to the carbon dioxide gas (CO2) in the air results in the production of organic compounds, principally carbohydrates or sugars, whose molecules contain carbon, hydrogen, and oxygen.

... XxMissFlirtyxX...In a particular population, the allele frequency of the ABO blood type alleles are as follows: IA is 20%, IB is 30% and i is 50%. If mating is random and the population is in Hardy-Weinberg equilibrium, what percentage of the population will have type O blood type
Answer:
The genotypic frequency F(ii) = 0.25 = 25%
Explanation:
Due to technical problems, you will find the complete explanation in the attached files
In the blood type cases involving the ABO group, the type of inheritance here is the co-dominance type of inheritance
The percentage of the population with type O blood will be 25%
Type A (IA) is dominant to type O (i) and at the same time type B (IB) is also dominant to type O (i).Using the equation - p² + 2pq + q² + 2pr + r² + 2qr = 1Where p² indicates the genotypic frequency with type A (AA) blood and q² indicates genotypic frequency of BB and r² indicates the genotypic frequency of OO.Since we are finding the percentage with type O blood (r²) where r (allelic frequency of type O) is 0.5 (50%)
r² = 0.5² = 0.25 = 25%.

(a) Describe why DNA replication is said to be a semiconservative process. Explain how random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism.
Answer:
DNA replication is semi-conservative because each helix that is created contains one strand from the helix from which it was copied. The replication of one helix results in two daughter helices each of which contains one of the original parental helical strands.
A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. ... Mutations can also occur as the result of exposure to environmental factors such as smoking, sunlight and radiation.
Btw :
stay safe! :3
(a) In order to understand why the replication of DNA is said to be semi conservative, there is a need to understand what really goes on during replication.
During replication, the two strands of the DNA first become separated.Each strand then makes a complementary copy of itself.The original double strand does not reform, instead, the old strands each forms a double strand by coupling with their newly synthesized complimentary strands.The fact that the 2 double strands DNA that forms at the end of the replication process each consist of one old and one newly synthesized strand is why replication is said to be semi conservative. The old strands remain conserved but are now separated into new double strands.
(b) Random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism due to a host of factors:
mistakes during replicationmutation due to external factors such as chemicals, UV radiation, etc.When this happens, the DNA sequence is altered and this alteration creates one or more phenotypic effects.

Explanation:
How does carbon cycle through Earth's systems? A. As fossil fuels are burned, carbon dioxide is made available for photosynthesis in animal cells. When the animals die, carbon is released into the soil, and the animal remains form new fossil fuels. B. Animals absorb carbon dioxide through their skin. Dead animals release carbon into the soil. Plants absorb the carbon from the soil and release carbon dioxide during photosynthesis. C. Plants absorb carbon dioxide through their leaves. Animals take in the carbon when they eat the plants. Animals exhale carbon dioxide. Dead plants and animals release carbon into the soilling D. Photosynthesis releases carbon dioxide into the atmosphere Cellular respiration uses carbon dioxide
Answer:
D. Photosynthesis releases carbon dioxide into the atmosphere Cellular respiration uses carbon dioxide.
Explanation:
Carbon dioxide is taken out of the air by the photosynthesis process to make carbon food for crops.
Animals and plants need a mechanism called respiration to remove carbon dioxide gas.
When combustibles are burned, carbon flows from fossil fuels to the air.

Answer:
The awnser would be their DNA is made of different codon sequences.
Explanation:
The reason is Kai gets her sequences from both her mom and dad and so do her parents from their parents and on and on.
The statement that best explains the characteristics of Kai with respect to her parents is as follows:
Their DNA is made of different codon sequences.Thus, the correct option is A.
Why Kai does not appear to be identical to her parents?Kai does not appear to be identical to her parents because of the process known as variation. Variations may be defined as the process of differences in traits of individuals of a progeny from each other and from their parents.
The codon that constructs the characteristics of the DNA significantly depends on the triplet of amino acid sequences that alter the formation of proteins which governs all the properties and mechanisms of living organisms including their appearances.
