Expert Answer
40.
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.
41.
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.
