Expert Answer:


If the base sequence on one strand of DNA is 5ˈ-AGGTCCG-3ˈ, then the base sequence on the complementary strand of DNA would be 3ˈ-TCCAGGC-5ˈ.

However, the sequence desired from the 5ˈ to 3ˈ end would be 5ˈ-CGGACCT-3ˈ.

So, the correct answer is option B.


Let L denote short hair and l denote long hair.

Since long hair trait is recessive to short hair,

True-breeding homozygous short-haired male = LL

Long haired female = ll

After crossing, LL × ll, all the progeny obtained would be the genotype, Ll.

This means that 100% of the progeny would be short-haired. All the kittens would look alike with short hair.

So, the correct answer is option A
