1. What is the relationship between DNA and gene expression? How do they depend on each other?


2. Why is it important for the “on” and “off” mechanism of gene regulation?



3. Since there are DNA segments that do not code for amino acids, what is their purpose?

Sagot :

Answer:

1. Gene expression is the process the cell uses to produce the molecule it needs by reading the genetic code written in the DNA. To do this, the cell interprets the genetic code, and for each group of three letters it adds one of the 20 different amino acids that are the basic units needed to build proteins.

2. gene regulation is at the bottom of what makes a cell decide to become a red blood cell, or a neuron, or a hepatocyte in the liver, or a muscle cell.

3. Most non-coding DNA lies between genes on the chromosome and has no known function. Other non-coding DNA, called introns, is found within genes. Some non-coding DNA plays a role in the regulation of gene expression. Non-coding DNA is just what it says; it's non-coding DNA.
