The Discovery of the Double Helix, 1951-1953

WebMar 31, 2024 · Complete answer: (a) The two strands of the DNA double helix are held together by a weak bond known as the hydrogen bonding. These bonds are formed between the complementary (opposite) base pairs of the DNA. There exist 3 hydrogen bonds between cytosine and guanine bases while 2 hydrogen bonds occur between the bases adenine … WebUnderstanding: • Helicase unwinds the double helix and separates the two strands by breaking hydrogen bonds. • DNA polymerase links nucleotides together to form a new strand, using the pre-existing strand as a template. DNA replication is a semi-conservative process whereby pre-existing strands act as templates for newly synthesised strands.
