Solution

Introduction

  • DNA, or deoxyribonucleic acid, is a complex molecule that stores all of an organism's information and is utilized to reproduce and maintain the organism.
  • The majority of DNA is used for structural maintenance, while certain sections are used to store genetic information and others are utilized to regulate the expression of genetic information as amino acids and protein molecules.
  • DNA does not interact with other molecules directly.
  • Rather, enzymes interact with DNA to extract information.
  • As a continuance of the hereditary source's qualities, a portion of DNA is passed down to the offspring.

Properties:

  • The length of DNA is around two meters.
  • Each chromosome is formed by wrapping DNA around proteins called Histones to form an 'X' shape.
  • Humans have 44 informational chromosomes (DNA) and two sex chromosomes as a result of this (DNA).
  • The largest chromosome, with roughly 8,000 genes, is chromosome 1.
  • With roughly 3,000 genes, chromosome 21 is the smallest.
