DNA STRUCTURE AND REPLICATION
DNA is usually a double-helix and has two strands running in opposite directions. Each chain is made of subunits called nucleotides. Each strand has a backbone made up of deoxy-ribose sugar molecules (5 sugars) linked together by phosphate groups. Each sugar molecule is covalently linked to one of four possible bases, Adenine, Guanine, Cytosine and Thymine. A and G are larger molecules (called purines) and C and T are smaller molecules (called pyrimidines). In the DNA, …showed first 75 words of 284 total…
