A mutation occurs in the genotype of an organism. This results in a beneficial phenotype being expressed. This organism now has a survival advantage. Therefore, it will live longer. This means it will hav...

DNA replication is semi-conservative, meaning existing strands are used as templates for new strands. The DNA is separated (unwinds) by the enzyme helicase. This enzyme breaks the H bonds between nucleoti...

Oxygen acts as the final electron acceptor in the electron transfer chain, resulting in the formation of H₂O. This is essential because without it, the electron transfer chain cannot function r...

exchange surfaces require a small diffusion distance enabling the fast exchange of compounds, good blood supply to maintain a concentration gradient. This allows for the most efficient diffusion

The major difference between both of these processes is why they are used, DNA replication is used for cell division in the S phase of the cell cycle. mRNA transcription is used in protein synthesis and t...
