In the following exercise you will be given a wild type (ancestral) DNA code that you will transcribe and translate into an amino acid sequence (remember start codons). In addition to the wild type code, you have been given five mutated sequences of the wild type code that you will also transcribe and translate. For each mutation you will determine the mutation type (substitution, insertion, deletion) and effect (silent, nonsense, missense, frameshift-missense, frameshift-nonsense) by comparing to the wild type. Wild type template strand:
3'TGTACTTCAAACCGATT5"
mRNA-
AA Seq.
Answer:
Wild type template strand
3'TGTACTTCAAACCGATT5'
Wild type template DNA strand after transcription give following mRNA sequence
5’ACAUGAAGUUUGGCUAA3’
This mRNA has five codons; out of five, four codons (AUG, AAG, UUU and GGC)encode aminoacid and one is stop codon (UAA). Therefore, after translation this mRNA gives following amino acid sequence
Methionine-Lysine-Phenylalanine-Glycine

Answer:
A
Explanation:
A: Venus rotates far more slowly than Earth
Look at the column that says Period of Rotation.
Venus has a rotation period of 243 days.
Earth has a rotation period of about 24 hours.
243 days is much longer than 24 hours, so this is true.
B: Venus's year is longer than Earth's.
The year is also another way to say Period of Revolution.
Venus's is about 224 days.
Earth's is about 365 days.
Venus's is actually shorter, so this is false.
C: Mercury is approximately twice the size of Earth.
Let's look at the Equatorial Diameter column.
Mercury's is 4,880 km.
Earth's is 12,756 km.
Mercury's is much smaller than Earth's, so this is false.
D: All of the above.
Since B and C are both not true, this is incorrect.
Therefore, the correct answer is A: Venus rotates far more slowly than Earth.

What happens during interphase that allows the two resulting cells to be the same as the
original cell?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. ... Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.
Which contributes to the movement of air masses
Answer:
The Movement of Air Masses: transporting warm air northward and colder air southward. Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses. A warm front marks the leading edge of this warm, moist air mass.

Which of the following statements concerning metagenomic sequencing is incorrect
Answer:
The correct answer is "proteins are extracted from an environment, fragmented, and adaptors are added".
Explanation:
The missing options of this question are:
A) Software aligns sequences and assemble large portions of genome.
B) The samples are subject to polymerase chain reaction for amplification.
C) The sequences of the amplified fragments are determined by next-generation methods.
D) Proteins are extracted from an environment, fragmented, and adaptors are added
The correct answer is option D) Proteins are extracted from an environment, fragmented, and adaptors are added.
Metagenomic sequencing refers to the amplification and determination of all nucleotide sequences in a sample, which might contain multiple microorganisms and viruses in order to understand the presence and proportions of microbiota. Metagenomic sequencing involves the use of next-generation methods, to amplify and characterize all the nucleotides sequences. It is false to affirm that the proteins are extracted directly from the environment in this technique, since metagenomic sequencing is focused on the nucleotide sequences.

Drag each label to the correct location on the map.
Identify the types of precipitation on the map. The color scale gives the rainfall amounts in inches.
The given question is incomplete as it lacks the map which is important, however the correct answer is attached:
Answer:
The correct answer is -
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.
Explanation:
As per the map and the scale presented on the map that indicates the rainfall in inches. The green area indicates that the rain fall in this area is one inch which is moderate as the the sky blue rainfall measurement is .5 inches which is half. However, the red area is the highest rainfall area in comparison to both of these which is about four inches.
On the basis of these it we can label all three boxes as per their rainfall amount that is,
Top box (green area) - moderate rain,
Middle box (sky blue area) - light rain, and
Bottom box (red area) - heavy rain.

What are the five main functions of nematodes in soil?
Answer:
Nematodes are the bacterial feeders, fungal-feeders, plant parasites, predators, and omnivores.
Explanation:
hope this helps :)
Answer:
Nematodes play an important role in nutrient cycling. In particular, they play a key role in the nitrogen cycle. Nematodes take in nitrogen and excrete it in a form that plants and bacteria can use.
Nematodes graze on bacteria, plants, and other soil organisms. In ecosystems, nematodes play a major role in regulating the populations of their prey organisms.
Nematodes carry fungi and bacteria in and on their bodies. As nematodes move through the ecosystem, they disperse the bacteria and fungi.
Nematodes are a part of food chains and food webs. They are an important food source in many ecosystems.
Nematodes impact the health of other organisms. Some help prevent, or suppress, disease by eating other disease-causing organisms. Other nematodes cause disease in plants and animals.

what is climate ?Climate is defined as a long-term pattern of weather in a specific area. the change weather can occur from hour-to-hour, day-to-day, month-to-month or even year-to-year.
the determination of climate can be occurred by a region’s climate system, this system consist of major components such as the atmosphere, the hydrosphere, the cryosphere, the land surface, and the biosphere.
The atmosphere is the variable part of the climate system where the composition and movement of gases surrounding the Earth can change radically, influenced by natural and human-made factors.
Changes to the hydrosphere, which include variations in temperature and salinity, occur at much slower rates than changes to the atmosphere.

In Guinea pigs, short hair (S) is dominant over long hair (s), and black coat color (B) is dominant over
albino (b). Both genes assort independently. A female of a true breeding line with a black coat and long
hair is mated with a short haired albino male (also from a true breeding line). (a) What are the
phenotypes of the F1 generation? Explain. (b) If F1 is mated, which percentage of the offspring will be
homozygous for both characters? Give all genotypes and phenotypes of these homozygotes.
Answer:
Explanation:
Short hair (S) is dominant over long hair (s), and black coat color (B) is dominant over albino (b).
A female of a true breeding line with a black coat and long hair is mated with a short haired albino male (also from a true breeding line)
parents genotype BBss x SSbb
gametes Bs x Sb
F1 generation geenotype BbSs
Phenotype- They are all with black coat and short hair
Mating of F1 BbSs x BbSs
Percentage of offspring homozygous for both characters:
Bb x Bb Ss x Ss
BB Bb Bb bb SS Ss Ss ss
1/4 1/4 1/4 1/4
1/4*1/4 = 1/16 = 0.0625 = 6% for each homozygous characters (BBSS-6% and bbss-6%)
The genotypes of the homozygotes are BBSS and bbss
The phenotype of BBSS is black coat with long hair
The phenotype of bbss is an albino with short hair
