DNA Ligase

DNA Polymerase

DNA Helicase

RNA primer

DNA polymerase break the covalent bonds forming the DNA

DNA helicase separates the two DNA chains

DNA helicase breaks the covalent bands forming the nucleotides

DNA polymerase catalyzes the addition of appropriate nucleotides to the DNA strand

DNA is replicated only at certain places along the chromosome.

DNA replication is both semicontinuous and conservative

Multiple areas of replication occur along the chromosome at the same time.

The leading DNA strand is synthesized discontinuously
