WebLike DNA polymerase, RNA polymerase adds nucleotides one by one to the 3′-OH group of the growing nucleotide chain. One critical difference in activity between DNA polymerase and RNA polymerase is the requirement for a 3′-OH onto which to add nucleotides: DNA polymerase requires such a 3′-OH group, thus necessitating a primer, whereas RNA … Web2 dagen geleden · SEL, Mentoring, Career Prep: Schools That Deliver What Parents Say They Want.

DNA Double Helix What is the Shape of DNA? - Ancestry
Web16 jun. 2014 · The DNA molecule is double helix, a spiral shaped ladder. The upright or backbone of the ladder is made of alternating pentose and phosphate groups held together by covalent bonds. The rungs or steps of the ladder consist of the bases. These bases are joined to the pentose sugars with covalent bonds. WebI knew him since we’re in high school. As a student, he is brilliant. As a person, a human being, he is outstanding! I thought his brain has never stop thinking even he is asleep. Looking forward to new challenges is already his DNA.
