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.

Answer:
The correct answer is species diversity.
Explanation:
Tundra refers to the ecosystem, which is found on the top of the mountain and in Arctic regions. It is the treeless region, where the rainfall is scant or negligible and climate is windy and cold throughout the year. However, despite the harsh conditions, the number of species found in the tundra ecosystem is quite high.
One can witness various kinds of organisms of distinct species in the region, thus, making it one of the diverse regions on the surface of the Earth. The mechanism, which is accountable for such species richness in the tundra region is the species diversity, which is illustrated as the entire sum of species found within a given community.
