11Alexandr11 [23.1K]

Answer:

D) 5'-ATGC-3' with 5'-GCAT-3'

Explanation:

In a double helix DNA, adenine always pairs with thymine and cytosine pairs with guanine. Also, the two strands of a double helix DNA are antiparallel, that is, the 5' end of one strand lies opposite to the 3' end of another strand.

Therefore, a DNA strand with base sequence 5'-ATGC-3' would have a complementary strand 5'-GCAT-3'.

meriva

Answer:

A. If neither parent expresses the trait, but the offspring does, both parents must be heterozygous for the trait.

Explanation:

If neither parents express the trait is because they are heterozygous and the dominant allele is being expressed over the recessive trait. When parents cross they have 25% of having an offspring that expresses the recessive trait, this means the offspring is a recessive homozygous. In the attached example 25% or 1/4 will have a short stem.
