Describe the modifications that can be done on a polypeptide chain to make it a fully functional

Biology
1 answer:
Nata [24]3 years ago
6 0

Answer: Polypeptide chains undergo some modifications before they become fully functional. Some of these modifications include: proteolytic cleavage, lipidation and glycosylation. Proteolytic cleavage refers to the removal of some amino acids from a polypeptide chain by proteases in order for the protein to become active. An example of a substance that is modified through this process is insulin.

A group of cells is assayed for DNA content immediately following mitosis (G1) and is found to have an average of 8 picograms of
mariarad [96]

Answer:

16 pg at the end of S

16 pg at the end of G2

Explanation:

A cell has 8 pg of DNA per nucleus in G1.

During S phase the DNA replicates, so every nucleus will contain double the normal amount of DNA that was present in G1. Therefore, at the end of S each nucleus would have 16 pg of DNA.

During G2 the cell continues growing and preparing for mitosis, but DNA content does not change: there are still 16 pg per nucleus.

A new life form was discovered on Mars, one based upon Silicon instead of Carbon. Explain what properties Silicon has that allow
Vesna [10]

Group IV of the Periodic Table of the Elements contains carbon (C), silicon (Si) and several heavy metals. Carbon, of course, is the building block of life as we know it. So is it possible that a planet exists in some other solar system where silicon substitutes for carbon? Several science fiction stories feature silicon-based life-forms--sentient crystals, gruesome golden grains of sand and even a creature whose spoor or scat was bricks of silica left behind. The novellas are good reading, but there are a few problems with the chemistry.

CRYSTALLINE CREATURES? Silicon can grow into a number of lifelike structures, but its chemistry makes it unlikely that it could be the basis for alien life-forms.</span>

Indeed, carbon and silicon share many characteristics. Each has a so-called valence of four--meaning that individual atoms make four bonds with other elements in forming chemical compounds. Each element bonds to oxygen. Each forms long chains, called polymers, in which it alternates with oxygen. In the simplest case, carbon yields a polymer called poly-acetal, a plastic used in synthetic fibers and equipment. Silicon yields polymeric silicones, which we use to waterproof cloth or lubricate metal and plastic parts.
