Thread: About dna

hello everyone!
I would like to know the difference among gene,DNA and a chromosome

Chromosomes are large, supercoiled strings of DNA.
Some parts of the chromosomes contain DNA sequences that contain information for protein production. These specific sequences are called 'genes'.

DNA is the actual chemical compound that genes are made of: deoxyribonucleic acid. The DNA molecule is a long chain of small units (nucleotides), each containing a "base" which can be guanine, adenine, thymine, or cytosine (G, A, T or C).

Each group of three bases forms a "codon" which encodes for a specific amino acid to be added to a protein. A sequence of codons make up a gene which describes a protein made from the corresponding amino acid.

A strand of DNA, which is a single huge molecule, contains long sequence of genes and makes up a chromosome (which also contains proteins and other things to give it structure).

Several chromosomes make up the complete genetic "blueprint" or genome of the organism.

Just to know, chromosomes are 46 in numbers 23 from each from both parents#

In Homo sapiens.
