It contains the blueprint for the synthesis of all proteins needed as building blocks and for proper functioning of the cell.

DNA

Genes

The proteins that cells synthesize doesn't determine what characters we express, what our bodies will be made of, and what can we do.

True

False

The nitrogenous base sequences determine the kinds of proteins our cells synthesize, which, in turn, determine the expression of a particular trait.

True

False

There are 46 chromosomes and around 35,000 genes in a human cell. Each chromosome may contain hundreds or thousands of genes that are linearly arranged along its entire length.

True

False

A gene could be 3001 base pairs long. There are around 3.1 billion nitrogenous base pairs in a complete set of human chromosomes.

True

False

It is a type of nucleic acid.

Deoxyribonucleic acid

Amino Acid

DNA is made up of these three components:

Five-carbon sugar (pentose) called deoxyribose

Phosphate group

Nitrogenous base

Proteins

James Watson and Francis Crick were the first scientist who described the DNA molecule as a “double helix.”

True

False

Nitrogenous bases are classified into:
