The correct answer is B. DNA.
DNA is a molecule that contains the genetic information of an organism. It is made up of two strands that are twisted together in a double helix shape. The information in DNA is encoded in the sequence of four different types of nucleotides: adenine (A), thymine (T), guanine (G), and cytosine (C). The order of these nucleotides determines the genetic code, which is used to build proteins.
DNA is passed down from parents to offspring through the process of reproduction. When a cell divides, its DNA is copied so that each new cell has a complete set of genetic information. This is how the genetic information of an organism is passed on from generation to generation.
RNA is another molecule that is involved in gene expression. RNA is similar to DNA in that it is made up of nucleotides, but it has a single strand instead of a double helix. RNA is used to create proteins by reading the genetic code in DNA.
Chromosomes are structures in the nucleus of a cell that contain DNA. Humans have 23 pairs of chromosomes, for a total of 46 chromosomes. Each chromosome contains a large amount of DNA, which is organized into genes. Genes are the basic units of heredity, and they determine an organism’s physical characteristics.
Carbohydrates are molecules that are made up of carbon, hydrogen, and oxygen. They are the main source of energy for the body. Carbohydrates are found in foods such as bread, pasta, rice, and potatoes.
In conclusion, the correct answer to the question “It is a heredity material and contains the genetic information which is passed on from one generation to another” is B. DNA.
