genes are in DNA
Chromosomes contain genes which are segments of DNA.
20.3% of your DNA contains genes
No - genes are the parts of DNA that code for a functional product (such as a protein). There are other parts of the DNA which are not genes.
No, DNA is the substance from which genes are made. Genetics is the study of genes and their expression.
Functional segments of DNA are called genes
DNA is the molecule that genes are made of. Chromosomes are the (arbitrary) clumping that genes form in cells.
Genes are the units of heredity, and are made up of segments of DNA
A gene is a portion of DNA. It takes multiple genes to make DNA.
Actually its the other way around. DNA is the structure that contains genes and passes them from generation to generation allowing traits to be inherited. I wish I could go into better detail but I'm more of a physics and chemistry kinda guy.
DNA is in genes, and genes are in chromosomes.
how is the information stored and coded in DNA and genes
Yes, because chromosomes are full of genes and DNA
