What is the origin of DNA replication?

• Random site in the DNA

• At the site which blocks initiation

• Specific site at which the DNA replication starts

• At the site at which the replication is terminated

In humans, where does DNA replication takes place?

• nucleus

• mitochondria

• cell membrane

• ribosomes

What happens at the start of a DNA replication?

• The bonds between nitrogenous bases and deoxyribose sugar break.

• The lagging strand produces Okazaki fragments.

• The phosphodiester bonds between the adjoining nucleotides break.

• The hydrogen bonds between nucleotides of two strands break.
