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.
Explanation:
Answer:
Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. After reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divide by mitosis to produce the haploid gametophyte. The new gametophyte produces gametes, and the cycle continues.
Explanation:
A satellite in a polar orbit passes over both poles, but the earth rotates beneath it. The time taken for each orbit of the earth depends on the height of the satellite. If the satellite is in a circular orbit 260 kilometers above the surface it will have an orbital period of two hours.
