Notes on dna replication
WebInitiation. The double-helix structure of the DNA molecule is unzipped by an enzyme called helicase. Helicase breaks the hydrogen bonds between the complementary base pairs in the DNA molecule. This separation of the two strands produce a ‘Y’ shape called the replication fork and the two separated strands act as a template for the synthesis of new strands. … WebThis arrangement helps keep the DNA molecule stable and intact and makes sure that genetic information is stored and passed on correctly. 9) ATCCAG. TAGGTC. The complementary strand to ATCCAG would be TAGGTC. In the ladder model of DNA, the base-pair rule says that adenine (A) always pairs with thymine (T) and cytosine (C) always pairs …
