Question

What are the steps for dna replication?

Answer 1

Process below

Step-by-step explanation:

DNA replication is the process by which a cell copies its DNA in order to produce new cells. The steps of DNA replication are as follows:

1. The DNA double helix unwinds and separates into two single strands.
2. An enzyme called helicase unwinds the DNA at the replication fork, breaking the hydrogen bonds between the nitrogenous bases and separating the two strands.
3. Another enzyme called primase adds short RNA primers to the single strands of DNA. These primers provide a starting point for the synthesis of new strands.
4. An enzyme called DNA polymerase begins adding new nucleotides to the single strands of DNA, using the existing strands as a template. DNA polymerase adds nucleotides to the 3' end of each strand, moving in the direction of the 5' end.
5. The newly synthesized strands are joined together by an enzyme called ligase, which seals any gaps between the nucleotides.
6. Once replication is complete, the cell has two identical copies of the original DNA molecule. These copies are used to create new cells, ensuring that each cell has the same genetic information as the original cell.

Answer 2

the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
