Explain How Different Enzymes Assist in the Replication of Dna.

As a 30-nm fiber the typical human chromosome would still be 01 cm in length and able to span the nucleus more than 100 times. In a cell an enzyme called primase builds a primer out of RNA.

A cell and PCR have different ways of getting started.

. It can only attach new nucleotides to an existing string of nucleotides. The mechanisms involved in transcription. Having discussed the DNA and protein molecules from which the 30-nm chromatin fiber is made we now turn to the organization of the chromosome on a more global scale.

The process of making a ribonucleic acid RNA copy of a DNA deoxyribonucleic acid molecule called transcription is necessary for all forms of life. DNA polymerase cant start building from scratch. One key player is an enzyme called DNA polymerasethe same enzyme thats used in PCR.

Clearly there must be a still higher level of folding even in interphase. DNA polymerase then extends the primer adding.
