Meiosis involves crossing over where chromosomes exchange genetic segments, resulting in different sets of chromosomes. Each time an egg or sperm created, it is different due to this recombination. Mitosis on the other hand is non-sex cells replicating exact copies of themselves which lead to no genetic variation as they aren't involved in producing offspring.
I'm pretty sure it is "c"
Answer:
<em>Some enzymes help break large molecules into smaller pieces that are more easily absorbed by the body. Other enzymes help bind two molecules together to produce a new molecule. Enzymes are highly selective catalysts, meaning that each enzyme only speeds up a specific reaction.</em>
Answer:
In prokaryotes (organisms without a nuclear membrane), DNA undergoes replication and transcription and RNA undergoes translation in an undivided compartment. All three processes can occur simultaneously.
In eukaryotes (organisms with a nuclear membrane), DNA undergoes replication and transcription in the nucleus, and proteins are made in the cytoplasm. RNA must therefore travel across the nuclear membrane before it undergoes translation. This means that transcription and translation are physically separated. The primary transcript, heterogeneous nuclear RNA (hnRNA), undergoes extensive post-transcriptional processing to make a messenger RNA (mRNA)molecule that can pass through the nuclear membrane.
