Answer:
a. 3′→5′ exonuclease activity = No proof reading
b. 5′→3′ exonuclease activity = No primer removal
c. 5′→3′ polymerase activity = No gap filling
Explanation:
<u>a) 3′→5′ exonuclease activity = No proof reading</u>
3′→5′ exonuclease activity of DNA polymerase I is responsible for proof reading so that if a wrong nucleotide is inserted during replication, it could be removed. So if a mutation will occur in the domain which is responsible for 3′→5′ exonuclease activity error prone DNA replication will occur.
<u>b. 5′→3′ exonuclease activity = No primer removal</u>
5′→3′ exonuclease activity is useful in removing primers so that appropriate nucleotides could be inserted in the lagging strand. But if mutation will occur in this part of DNA polymerase I then primer will not be removed and replication of lagging strand will be at halt.
<u>c. 5′→3′ polymerase activity = No gap filling</u>
5′→3′ polymerase activity of DNA polymerase I, joins the nucleotides in the lagging strand where the gaps have been created after removal of primer. So the gaps created after removal of primer in the lagging strand will not be filled if there will be a mutation in this segment of DNA polymerase I.
Answer:
Climate change affects patterns of migration. Global warming also influences the routes of many migratory birds and their annual migration rhythm. A lot of migratory birds change their routes, shorten or completely cancel their journey as a result of changing temperatures.

Answer: Option A.
Explanation:
Maltoporin is a membrane protein. It forms trimetric structure that facilitate the translocation of maltodextrins across outer membrane of E.coli bacteria. It is responsible for the guided diffusion in E.coli. it recognised bacteriophage sequence. It formed water filled pores across the outer membranes of gram negative bacteria. The lining of channel with maltoporin has a series of aromatic side chains stranded in a helical pattern matching the relative curvature of the protein backbone, thus providing little restriction to transport.
Answer:
Fossil B is the same age as the index fossil.
Explanation:
TOO LATE BUSTER
Answer:
Explanation: The possible genotypes from this cross are Rr, rr, Rr, and rr. So, that means two offspring will be red and two will be white. The percentage chance for each phenotype is: 50% chance for red flowers and 50% chance for white flowers.
