NEET BIOLOGY

Detailed explanation-1: -These instructions are stored inside each of your cells, distributed among 46 long structures called chromosomes. These chromosomes are made up of thousands of shorter segments of DNA, called genes. Each gene stores the directions for making protein fragments, whole proteins, or multiple specific proteins.

Detailed explanation-2: -The sequence of DNA bases is arranged into genes, most of which contain the instructions to build a protein. DNA stores information in the sequence of its bases. The information is grouped into genes.

Detailed explanation-3: -In order for a cell to manufacture these proteins, specific genes within its DNA must first be transcribed into molecules of mRNA; then, these transcripts must be translated into chains of amino acids, which later fold into fully functional proteins.

Detailed explanation-4: -Virtually every cell in the body contains deoxyribonucleic acid (DNA). It is the genetic code that makes each person unique. DNA carries the instructions for the development, growth, reproduction, and functioning of all life.

Detailed explanation-5: -In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.
