Answer:
Thymidine dimers is likely to be repair as soon as it is originated but if left unrepaired then it causes frame shift mutations.
Explanation:
In case of Bacterium if UV irradiation induces covalent linkage of two thymidine present adjacently to each other or on a single strand to make thymidine dimers.
These either excised via DNA repair enzyme like Endonuclease V and the proof reading activity of DNA polymerase I enzyme help in incorporation of nucleotide by taking the unmutated original strand as a template.
These dimers if not excised before second round of replication than the sequence of newly synthesized strand will be altered. As DNA polymerase III enzyme read thymidine dimers as single thymidine nucleotide and incorporate only 1 adenine in the newly synthesizing complementary strand which results in frame shift mutations
It is the mutation in which reading frame of codons is shifted or altered due to deletion or addition of a single nucleotide.
I'm going to assume it is a fill in the blank
So the answer would be fat
It can last from 1 to 4 hours
Examples of stimuli are the weather, sound, the cold, light, taste, color, and gravity.
- When you hear a loud noise you get scared and scream
- When it is hot outside you sweat
The chromatids are made of a substance called chromatin. This is a single, very long strand of DNA. ... The chromatin is copied, so you now have 92 strands, that are each spiraled up to form the chromatids. The 2 copies of each chromatid are joined together by a centromere to form a chromosome.
