Is DNA made up of protein?

While DNA is made of nucleotides, proteins are made of amino acids, a group of 20 different chemicals with names like alanine, arginine, and serine. The genetic code enables a cell to translate the nucleotide language of DNA into the amino acid language of proteins.

In this way, is DNA made up of genes?

A gene is the basic physical and functional unit of heredity. Genes, which are made up of DNA, act as instructions to make molecules called proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.

What is the difference between a gene and DNA?

Genes contain DNA (deoxyribonucleic acid). DNA is the chemical basis of heredity. Think of it this way: DNA is in genes, genes are on chromosomes. When "mapping" all genes on all human chromosomes was first seriously conceived, it was called the Human Genome Project - a combination of gene and chromosome.

Do genes make up proteins?

It consists of two major steps: transcription and translation. Together, transcription and translation are known as gene expression. During the process of transcription, the information stored in a gene's DNA is transferred to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
