The end result is having two identical daughter cells.
DNA polymerase III has a subunit for proofreading during DNA replication. As replication continues and
the polymerase III enzyme detects a mismatched base pair, through a deformity in the double helix structure, the
polymerase backs up, nicks the mismatched base and replaces it with the correct
base before continuing replication.
Answer:
Option B is correct
Explanation:
Given -
"Ability to taste the chemical phenylthiocarbamide" is autosomal dominant while its inability is recessive.
Autosomal dominant means that even if one l
Let the allele for dominant trait i.e "Ability to taste the chemical phenylthiocarbamide" be represented by "T"
and the allele for recessive trait i.e "Inability to taste the chemical phenylthiocarbamide" be represented by "t"
Genotype of a taster woman with a nontaster father is Tt
Genotype of a taster man who in a previous marriage had a nontaster daughter is also Tt
Tt * Tt
TT, Tt, Tt, tt
Therefore probability of being a taster is , and the probability of being a nontaster is
Probability that their first child will be a taster girl is equal to
Probability of being a taster Probability of being a girl
Thus, option B is correct
