Answer:
C
Explanation:
The damage to DNA usually occurs where there are two consecutive thymine nucleotides on a DNA strand. The energy from the UV light causes the two dimers to form a cyclobutane pyrimidine structure. Proofreading and repair mechanism of DNA find it difficult to repair this kind of damage on DNA. During replication, therefore, DNA polymerase is unable to replicate this region hence leading to a mutation on the replicated strand at this local point.
Explanation:
Homozygous Red, or Homozygous Dominant: RR
Yellow fruit must be homozygous recessive, or else the yellow would show: rr
Plant 1 Genotype: RR
Plant 2 Genotype: rr
The punnet square is attached.
The Genotypic ratio is: 4:0 or just Rr because the offspring turned out to be 100% heterozygous.
The Phenotypic ratio is just red, because no other colors come out of the offsping.
Hope this helps :)
Answer:
Option D. Ten per cent of the peptides generated are 8-9 residues in length is the correct answer.
Explanation:
An efficient derived from constitutive proteasome is called immunoproteasome. Its expression is highly visible in immune cells. It has an important role in immune system which is to degrade proteins of viral origin and intracellular proteins into smaller proteins. (See image for more detailed explanation)
