B. Macromolecules is the answer.
Answer:
b. 1 long-stemmed plant: 1 short-stemmed plant
Explanation:
The short-stemmed plant would have genotype(tt) and the heterozygous long-stemmed plant would have the genotype(Tt). So when they will cross with each other half of the offspring will be long-stemmed plants and half will be short-stemmed plant.
T t
t Tt tt
t Tt tt
So the offspring which have Tt genotype will be tall and the offspring which have tt genotype will be short. Therefore the correct answer is b. 1 long-stemmed plant: 1 short-stemmed plant.

Explanation:
Gene mutations can best be described as changes in the (3) nucleotide base sequence in DNA.
Answer:
D) 3' TGTAGTGCGCGCGT 5'
Explanation:
DNA strand: 5' ACATCGACGCGCGCA 3'
compliment: 3' TGTAGCTG CGCGCGT 5'
DNA strands are antiparallel which means that if you're given a 3' to 5' strand, the complementary DNA strand will be 5' to 3'. If you are given a 5' to 3' strand, the complementary strand will be from 3' to 5'.
The other thing to remember for <u>DNA </u>complementary strands <u>only</u> is:
- A always pairs with T
- G always pairs with C
(for DNA only!!!!) This is one of Chargaff's principles.
If you're asked to find the RNA sequence, A pairs with U. not T! Thymine does not apply to RNA. G still pairs with C though.
