Chromosome is part of a cell that carries hereditary material inform of genes, it contains DNA molecules tightly packed around histone proteins. X and Y are the sex chromosomes which influences the sex of an individual. Chromosome 21 is the smallest autosome in the human genome and exists in two pairs one inherited from either parent. In this case, the answer is the Y chromosome; sex is determined by the SRY gene which is responsible of the fetus to male. Other genes on the Y chromosome are important for male fertility.

Which is the DNA tehory? How do we know the DNA contains genetic information?

ValentinkaMS [17]

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code. Human DNA has around 3 billion bases, and more than 99 percent of those bases are the same in all people. DNA sequencing theory is the broad body of work that attempts to lay analytical foundations for determining the order of specific nucleotides in a sequence of DNA
