Flower color in the garden pea is due to two interacting genes, A and B. If either gene is recessive (aaB_, A_bb, or aabb) then the phenotype is white. A dominant allele must be present at both genes for flower color to be purple. After a testcross of an individual with a genotype of AaBb, what proportion of the progeny will have purple flowers

1. When DNA is duplicated from mRNA which DNA, mRNA uses a U nucleotide instead of T.

2. If the mRNA sequence is GUACUGUAC, the DNA Sequence is CATGACATG.

Explanation:

1. The only thing that changes from a DNA sequence to an RNA sequence is that the thymine (T) in DNA is changed to Uracil (U) in RNA.

2. There should be no Uracil (U) in a DNA sequence–– only ATCG. Just matching with the given pairings.

G can transcribed to C.

C can be transcribed to G.

A can be transcribed to T.

U can be transcribed to A.
