The Fundamentals of DNA Replication

TLDRDNA replication is a crucial process that allows cells to replicate and make more cells. It occurs in a semi-conservative fashion, where old parental strands are used as templates to create new DNA strands. Replication occurs in a 5' to 3' direction and is bi-directional. The process involves initiation, elongation, and termination.

Q&A

Why is DNA replication important?

—DNA replication is important because it allows cells to replicate and make more cells. It ensures the accurate transmission of genetic information from one generation to the next.

How does DNA replication occur?

—DNA replication occurs in a semi-conservative fashion. The double-stranded DNA molecule unwinds, and each parental strand serves as a template for the synthesis of a new complementary strand.

What is the direction of DNA replication?

—DNA replication occurs in a 5' to 3' direction. This means that new nucleotides are added to the 3' end of the growing DNA strand.

What is the role of replication forks in DNA replication?

—Replication forks are the areas where the double-stranded DNA molecule is unwound, and new DNA strands are synthesized. They are formed at the origin of replication and move in opposite directions.

What are the stages of DNA replication?

—DNA replication involves three stages: initiation, elongation, and termination. Initiation is the beginning of the replication process, elongation is the synthesis of new DNA strands, and termination is the completion of replication.
