Scientists have discovered that 99.9% of the gene sequence is shared by all humans a. true b. false

True

Explanation:

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). Theirasic makeup includes C, H, O, P; they contain phosphate group 5 carbon sugar does nitrogen bases which may contain single to double bond ring.

Genomics is the study of the genome, an organisms complete set of genetic information contained within its cells. DNA makes up the genome and  encodes a persons gene sequence. The majority of DNA is said to be conserved across species; meaning that all members within a species have almost identical DNA, and are closely related to each other; humans are 99.9% similar.

The remaining 0.1% is determined by normal human variation, arising from mutations, and genetic variants and mediate distinct traits like height, eye colour, hair types and bone structure. This is significant, as scientists discovered that the human genome consists of over 98.5% non- coding DNA, only some of which may regulate around 1.5-2% of our genes are encoded into proteins which essential for human life.
