Which of the DNA repair mechanism can be template-independent and require polymerase activity?

Biology
1 answer:
Westkost [7]3 years ago
5 0

Answer:

d. error-prone repair

Explanation:

DNA polymerases are the enzymes responsible for synthesizing DNA, not only making faithful replicas of our chromosomes, but also carrying out the necessary repairs for the proper maintenance of your genetic information. Either due to the intensity of the genotoxic damage or due to defects in the repair machinery, the ideal situation of having a pristine, original mold of DNA for copying is not always possible, which explains the existence of a special type of DNA polymerases, specialized in tolerating various DNA lesions through a copy process called "translesion synthesis" which is an "error-prone" or error-guaranteeing.

There is also a new human translesion DNA polymerase, perhaps the oldest of all, and that is capable of initiating the synthesis of new DNA chains acting as a primase. This enzyme, called PrimPol, is present in both cellular compartments that contain DNA (the nucleus and mitochondria). Through gene silencing experiments it was shown that PrimPol is necessary for mitochondrial DNA replication, probably tolerating the high oxidative damage associated with the respiratory activity of these organelles.

What is the role of alveoli in respiration
Burka [1]

Answer:

<em>What is the role of alveoli in respiration ⇔ Alveoli are the place where the exchange of gases takes place. The outer part of alveoli has blood vessels. These vessels are carrying Co2 rich blood to exchange at the alveoli. The O2 from the alveoli is diffused into the blood while co2 is sent into the lungs. That O2 rich blood is then carried to heart to pump it to the whole body. and this process continues. </em><em>The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out.</em>

Glycogen Synthase Kinase:_______.
horrorfan [7]

Answer:

A. Will only phosphorylate glycogen synthase (GS) after GS has been phosphorylated by casein kinase.

Explanation:

Glycogen synthase kinase (GSK) is a type of enzyme capable of phosphorylating serine and threonine residues on the glycogen synthase (GS). The insulin hormone activates the synthesis of glycogen by dephosphorylating GS, but it is a mechanism that depends on the previous phosphorylation of GS by Casein Kinase (CK). GSK is also known to phosphorylate the insulin receptor (IRS), and thus controlling glucose metabolism.

During the 18th century what was England’s view on inoculations
stepan [7]

Answer:

For many centuries, smallpox devastated mankind. In modern times we do not have to worry about it thanks to the remarkable work of Edward Jenner and later developments from his endeavors. With the rapid pace of vaccine development in recent decades, the historic origins of immunization are often forgotten. Unfortunately, since the attack on the World Trade Center on September 11, 2001, the threat of biological warfare and bioterrorism has reemerged. Smallpox has been identified as a possible agent of bioterrorism (1). It seems prudent to review the history of a disease known to few people in the 21st century.

Edward Jenner  is well known around the world for his innovative contribution to immunization and the ultimate eradication of smallpox (2). Jenner's work is widely regarded as the foundation of immunology—despite the fact that he was neither the first to suggest that infection with cowpox conferred specific immunity to smallpox nor the first to attempt cowpox inoculation for this purpose.
