NEET Botany Molecular Basis of Inheritance Questions Solved


DNA replication in eukaryotes differs from replication in bacteria because:
(a) Synthesis of the new DNA strand is from 3' to 5' in eukaryotes and from 5' to 3' in bacteria
(b) Synthesis of the new DNA strand is from 5' to 3' in eukaryotes and from 3' to 5' in bacteria
(c) There are many replication forks in each eukaryotic chromosome and only one in bacterial DNA
(d) Synthesis of the new DNA strand is from 5' to 3' in eukaryotes and is random in prokaryotes

In prokaryotes, DNA molecules contain a single origin of replication and a single replicon. These origin sites are longer than eukaryotic  origin sites.

Eukaryotic DNA is very large and is organised into chromosomes. There are multiple origins of replication on each chromosome. DNA replication can independently initiate at each origin and terminate at corresponding termination sites.
