Key enzymes involved include DNA helicase, DNA primase, DNA polymerases, and DNA ligase which work together to replicate DNA in a semi-conservative manner beginning at origins of replication on the DNA. The document discusses different forms of DNA structure that can be adopted based on environmental conditions.
This document describes the process of DNA replication in eukaryotes. It occurs in S phase of the cell cycle and involves three main stages: initiation, formation of the initiation complex, and elongation. Initiation requires the assembly of pre-replication complexes containing ORC, Cdc6, Cdt1 and MCM proteins.
7 DNA Replication DNA replication is the process where a molecule of DNA makes an exact copy of itself. (see foldable model) DNA "unzips", which means it breaks hydrogen bonds...
The document summarizes the central dogma of molecular biology: DNA is transcribed into RNA, which is then translated into protein. It describes the processes of DNA replication, transcription of DNA to mRNA, and translation of mRNA to proteins using tRNAs and ribosomes.

On your own: • Where does DNA replication occur in a eukaryotic cell? • Nucleus • What are the base-pairing rules for DNA? • A-T, G-C • What would be the complementary strand for the DNA strand A-T-T-C-G-G-A-T-C? • T-A-A-G-C-C-T-A-G • How do the two new DNA molecules that result from DNA replication compare with each other?
DNA REPLICATION DNA Replication – process in which a DNA strand is copied • DNA polymerase is an enzyme that unzips the double stranded DNA. • Free nucleotides come in and pair with bases. • Two new double strands of DNA are made. RNA – Ribonucleic Acid • Chemically, RNA is very similar to DNA.
This animation shows the process of DNA replication, including details about how the mechanism differs between the leading and lagging strand. DNA replication starts with the separation of the two DNA strands by the enzyme helicase. The two strands are referred to as the 3' and 5' strands based on the direction by which the component ...
DNA replication is the process by which DNA copies itself. It occurs during cell division and involves unwinding the DNA double helix, synthesizing new strands that are complementary to the original strands, and producing two identical DNA molecules each with one original and one new strand.
Cells must make a copy of DNA (replication) before the cell divides so that each cell has a copy of the genetic code. Question: What is the genetic code used for? Answer: making proteins Why are proteins important? Blood cell with the correct DNA sequence for shape. Proteins are what make us different. Blood cell with an incorrect DNA sequence ...
