How many strands do dna have
Web2 sep. 2024 · Strands of DNA are made up of nucleotides that have phosphate groups, ribose sugar, and nitrogenous bases. They are twisted around each other and form a ladder-like structure known as a double helix. In DNA, hydrogen bonds play an important role in giving intrinsic stability to the molecule. WebDNA is a double helix; 2 strands, each one has coding areas ( which are 2% and maybe less) and non-coding areas . Within the gene itself there are non-coding sequences …
