WebThe sister chromatids then separate completely from each other at anaphase to become individual chromosomes. In this manner each daughter cell formed by a mitotic cell division inherits one copy of each paternal chromosome and one copy of each maternal chromosome and is therefore unchanged in its genetic composition from the parent cell. WebAnswer: 1.Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. 28.
