Dna replication and heredity
WebDNA replication follows base-paring rules: A-T, C-G. Sometimes during DNA replication, a base is inserted, deleted, or substituted with a different one, changing the DNA sequence of a gene. Changes in the DNA sequence of a gene can lead to changes in the protein it codes for. Give each student or pair of students one copy of the instructions ... WebDNA replication occurs during interphase and duplicates the amount of DNA in a cells nucleus just prior to cell division. Cells differentiate because they need to become …
