Answer:
The correct answer is a gene
Explanation:
The DNA segment that carries information for coding one protein or polypeptide is called a gene. According to one gene-one polypeptide hypothesis, each gene is responsible for making a single chain of the polypeptide.
Originally it was said that one gene codes for one enzyme but later it was found that some gene also codes for non-enzyme proteins and single polypeptide chains. So after this research, the theory was modified and one gene-one polypeptide theory came. Therefore the right answer is gene.
Any change or random error in a DNA sequence is called a mutation.
The geosphere supplies all the raw materials that all living things use to build their bodies. The sun supplies the energy directly or indirectly.. (There are some exceptions, some life forms have been found in deep sea vents and produce their energy chemically. And microorganism have been found at great depths in drill holes recently, little is known about them.)
