Z-DNA has a left-handed double helix structure. It is said to be found during the start of a gene. When does DNA replication occur? DNA replication occurs in the S phase of the cell cycle.
Revise structure and replication of DNA for your Higher Human Biology exam with Bitesize Scotland interactive practice quizzes covering feedback and common errors.
The helicase unzips the double-stranded DNA for replication, making a forked structure. The primase generates short strands of RNA that bind to the single-stranded DNA to initiate DNA synthesis by ...
The flow follows the same rhythm as replication of DNA does -- and when it does not, the cells regulate the process to align the two. "We can see that these processes follow the same periodic rhythm.
The first step in DNA replication requires the assembly of a group of proteins called the Origin Recognition Complex (ORC). Researchers have determined how the ORC assembles during the cell ...
During DNA replication, the classic double helix can temporarily rearrange into an alternative structure known as a DNA three ...
