Question

How are DNA, chromosomes and genes related?

Answer 1

Gene is called the segment of DNA. Chromosomes are thread-like structures present inside the nucleus of the cell.

Complete answer:
Genes are deoxyribonucleic acid (DNA) segments that carry a code for a particular protein that operates in one or more cell types in the body. Chromosomes are structures inside cells that contain the genes of an individual.
In chromosomes, which are in the nucleus of cells, genes are found.
A chromosome includes genes from hundreds to thousands.

There are 23 pairs of chromosomes in every single human cell, for a total of 46 chromosomes.
A phenotype is any feature determined by a gene and is often determined by more than one gene.
Mutated genes that are inherited or that are the result of a new gene mutation are caused by certain characteristics.

Deoxyribonucleic acid consists of genes . The code, or blueprint, used to synthesize a protein is found in DNA. Similar to the sizes of the proteins for which they code, genes differ in size. Each molecule of DNA is a long double helix, resembling a spiral staircase with millions of steps. The steps of the staircase consist of pairs of four types of molecules called bases (nucleotides). Base adenine (A is paired with base thymine (T) in each step, or base guanine (G) is paired with base thymine (T).

Note: 1)Chromosomes are composed of DNA and histone proteins.
2)DNA is a biomolecule made of sugar, phosphorus and nitrogenous bases.
3)Genes are DNA segments used for coding proteins.
