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. WebChromosomes are made of DNA, and genes are special units of chromosomal DNA. Each chromosome is a very long molecule, so it needs to be wrapped tightly around proteins …
