WebPrior to S-phase each chromosome is a single chromatin fiber. During S-phase the DNA is replicated and this results in two chromatin fibers (known as sister chromatids). However, these chromatin fibers are attached to each other at the centromere and together they make up a post S-phase chromosome. WebJul 8, 2024 · Step 1: Formation of Replication Forks. Before DNA can be reproduced, it must first be “unzipped” into two single strands. Adenine (A), cytosine (C), thymine (T), and guanine (G) are the four nucleotides that form pairings between the two strands of DNA. Adenine only binds to thymine, while cytosine only binds to guanine.
