Pls solve the biology questions

Reviewing Main ideas

1. Replication assures that every cell has a complete set of identical, genetic information and makes a copy of the DNA so it can be passed to the new cell. ... DNA polymerase binds the nucleotides together and forms new strands complementary to each template.

2. DNA is a double helix. So during replication, it unwinds and separates into 2 strands. 1 strand will be called the non-coding and the other will be called the coding strand.

The non-coding strand will be the template for the new one.

3. The DNA Polymerase detects if there is an error, it removes the incorrect nucleotide and replaces it with the correct one.

Critical Thinking

4. The main function of DNA polymerase is to synthesize DNA from deoxyribonucleotides, the building blocks of DNA. ... By contrast, RNA polymerases synthesize RNA from ribonucleotides from either RNA or DNA. When synthesizing new DNA, DNA polymerase can add free nucleotides only to the 3' end of the newly forming strand.

5. Why is it important that human chromosomes have many origins of replication? because cells need to be copied quickly to replace cells in our bodies that have died, having many origins of replication helps the process happen faster.

The words that are in bold are the words you should write down. You don't have to write the whole thing. The other words are just for a better understaning.
