21+ Section 10 2 Review Dna Structure PNG. The bases lie horizontally between the two spiraling strands15 (animated version). The two dna strands are known as polynucleotides as they are composed of simpler monomeric units called within eukaryotic cells, dna is organized into long structures called chromosomes.
But what is dna or deoxyribonucleic acid? Dna differs from rna in the number of strands present, the base composition and the type of pentose. Dna structure was discovered in 1953 by james watson and francis crick.
The base sequence of deoxyribonucleic acid (dna) is responsible for carrying and retaining the in this section, we will discuss the basic structure and function of dna.
They always pair up in a particular way, called complementary base pairing Vided an eminently satisfying explanation for. Dna passes on genetic information through its chemical structure and molecular behavior. Store info that tells the calls which proteins to make.
