When does DNA replication take place in a cell?
The process of DNA replication takes place during cell division. The DNA replication takes place during S sub stage of interphase. In prokaryotes, DNA replication is initiated before the end of the cell cycle. Eukaryotic cells can only initiate DNA replication at the beginning of S phase. 2. Replication Site:
What are the evidences for semi-conservative DNA replication?
Evidences for Semi-Conservative DNA Replication 4. Models for Replication of Prokaryotic DNA. DNA replicates by “unzipping” along the two strands, breaking the hydrogen bonds which link the pairs of nucleotides. Each half then serves as a template for nucleotides available in the cells which are joined together by DNA polymerase.
Which is the most accurate model of DNA replication?
There are three models which explain the accurate replication of DNA. These are: (i) dispersive replication, (ii) conservative replication, and (iii) semiconservative replication (Fig. 17.1). According to this model of replication the two strands of parental DNA break at several points resulting in several pieces of DNA.
