between the 3’ carbon of a deoxyribose if a nucleotide and the 5’ carbon on the phosphate on the next nucleotide

what are 2 strands of DNA

they are anti parallel which means one strand runs 5’-3’ and the other runs in a 3’-5’ direction

every thing about prokaryote

the have cells such as bacteria and archaea these cells have no nucleus so chromosome DNA is found in the cytoplasm

they have a singular circular chromosome in the cytoplasm and have additional pieces of DNA called plasmids

Eukaryotic

they have cells such as plant animal fungi and they do have a nucleus so liner chromosome is fount in the nucleus

they have liner chromosome rather than circular they can be tightly curled and packaged with proteins called histone

circular chromosome in mitochondria and chloroplast

yeast contains plasmids
