1. Describe how the process of DNA replication results in the transmission and/or conservation of genetic information.

- DNA replication is the process of DNA being copied before cell division occurs.
- During this process, the double-stranded helix will unwind and split apart.
- Each half of the DNA strand will then serve as a template to make a new complementary strand.
- The new nucleotides will bond with their complement on the original strand. This is called semiconservative replication.
- At the end of replication, there are 2 identical DNA strands.
- This method ensures that replication will be exact and each new cell will receive the proper DNA after division.
- The process is extremely accurate—only 1 mistake per 1 billion nucleotides. The cell has proofreading enzymes that look for errors during the process. If a mistake is made, it is called a "mutation." Mutations can be helpful, harmful, or neutral.

Final answer:

DNA replication involves the copying of two DNA strands, resulting in identical sequences and ensuring proper genetic transmission during cell division.

Explanation:

During DNA replication, each of the two strands that make up the double helix serves as a template from which new strands are copied. The new strand will be complementary to the parental or 'old' strand. Each new double strand consists of one parental strand and one new daughter strand. This is known as semiconservative replication. When two DNA copies are formed, they have an identical sequence of nucleotide bases and are divided equally into two daughter cells.
