DNA replicates by the semiconservative model of replication. This model states that during replication of double stranded DNA, the two strands separate and each separate strand is then used as a template to make a new strand.
No, transcription and replication are different. DNA replication is the process where one double helix of DNA is duplicated into two identical double helixes which are also identical to the mother DNA.RNA transcription is the process by which a messenger RNA copy of the active strand of a DNA helix is created.I hope that helps. Most of the DNA in a eukaryotic cell is in the nucleus, and that is where DNA replication and transcription occur. In eukaryotic cells, mitochondria and chloroplasts a â¦ lso contain DNA, which performs replication and transcription inside these organelles. In prokaryotic cells there is no nucleus.
