templates

original molecules are used as _______ for synthesis of new DNA strands in DNA replication

The DNA strands that can be copied to produce new DNA strands are called the

templates

DNA replication relies on the Blank______ of DNA strands according to the Blank______ rule.

complementarity; AT/GC

The site within a chromosome where DNA replication begins is known as the _____ of replication

origin

During DNA synthesis, the sites where the two template strands are unwound and new DNA is made are called what?

Replication forks

During what process are parental DNA strands used as templates for the synthesis of new DNA strands?

Replication

DNA replication is described as Blank______ because DNA replication proceeds outward from two replication forks.

bidirectional

Why do eukaryotic cells have multiple origins of replication?

To ensure timely replication of multiple, relatively large chromosomes

DNA replication proceeds outward from two

replication forks

replication forks

sites where the template strands are unwound and new DNA is synthesized.

DNA replication of the prokaryotic chromosome:

has a single origin of replication and is bidirectional.

Helicase

Causes DNA strand separation at the origin of replication

Topoisomerase

Relieves coiling in DNA strands ahead of the replication fork

Single-strand binding protein

Prevents the two DNA template strands from re-forming the double helix
