Detailed explanation-1: -A gene is a small section of DNA? that contains the instructions for a specific molecule, usually a protein?. The purpose of genes? is to store information. Each gene contains the information required to build specific proteins needed in an organism. The human genome? contains 20, 687 protein-coding genes.
Detailed explanation-2: -A gene is a length of DNA code that allows for proteins to be made.
Detailed explanation-3: -Genes are stretches of DNA containing the instructions to build biological molecules such as proteins. An individual usually has two copies of each gene. Different versions of the same gene are called alleles.
Detailed explanation-4: -The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.
Detailed explanation-5: -Gene: Gene is known as the length of DNA as it codes for protein. Wilhelm Johannsen, a Danish botanist, plant physiologist, and geneticist, coined the term “gene” in 1909. Genes can experience sequence mutations, which result in various alleles, or variants, in the population.
