Replication Starts off a Unique Point on Bacterial and Viral Chromosomes 4. Replication of Both Strands Proceeds by the Addition of Nucleotide Monomers in the 5'-3' Direction and Others. Rule # 1.

The following points highlight the top two models of chromosomes. The models are: 1. Multiple Strand Models 2. Single Strand Models. Model # 1. Multiple Strand Models: a) Simple Multi-Stranded Model: According to this model the chromosome consists of 64 double helices of DNA arranged in a parallel number, and twisted together like the strands of a rope. The difficulty [...]
