Answer:
Codons after the mutation are not exactly the same as before mutation, because one base was deleted, changing the sequence of codons.
Codons before mutation: ATG TGC GAA ACT TTG GCT
<em>Only the first one (ATG) might coincide with one of the codons before mutation. </em>
Explanation:
Genetic information for the aminoacids assembly during the protein synthesis is stored in short sequences of three nucleotides named codons in the DNI or mRNA. Each of the codons represents one of the 20 amino acids used to build the protein. There are a total of 64 codons. 61 codify amino acids, one of these amino acids is also the start point of protein synthesis, and the left three codons are stopping translation points.
The Sequence before mutation ATGCTGCGAAACTTTGGCTGA
Codons: ATG CTG CGA AAC TTT GGC TGA
The Sequence after mutation ATGTGCGAAACTTTGGCTGA
Codons: ATG TGC GAA ACT TTG GCT
<em>Only the first one (ATG) might coincide with one of the codons before mutation. </em>
Answer: C. It was heterozygous for both genes.
Explanation: To produce a generation that has individuals with trait for colored aleurone in the kernels, the plant being analised has to have a dominant allele R. In the same way, to have offspring with the recessive trait, it has to carry the recessive allele r. So, the unknown plant has to be heterozygous for colored aleurone in the kernels, Rr.
The same thought can be applied to plant color: Since there are green and yellow plants, the unknown plant has to be heterozygous for that trait, Yy.
In conclusion, the unknown plant is heterozygous for both genes.
Answer: The correct answer is C. Vacuum.
Explanation: It was correct on my test : )
It’s 5211 bc a is 5, B is 2 and D is 1! hope this helps!
