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. Only mutations in germ cells (eggs or sperm) can be passed to offspring. iphonese 13 比較 https://artisanflare.com
