Biology

valina [46]3 years ago
3 0

Explanation:

Biotic factors such as the presence of autotrophs or self-nourishing organisms such as plants, and the diversity of consumers also affect an entire ecosystem. Abiotic factors affect the ability of organisms to survive and reproduce. Abiotic limiting factors restrict the growth of populations.

Processing of the mRNA begins before transcription of eukaryotic mRNA's is complete. The end of the mRNA is prepared for recogni
omeli [17]

Answer:

Capping occurs at <u>5' end of the mRNA</u>.

Explanation:

Eukaryotic  cell process the mRNA in nucleus before it moved to the cytoplasm for protein synthesis.

The RNA that is direct copy of DNA is called primary transcript.

The molecule that's directly made by transcription in one of your (eukaryotic) cells is called a pre-mRNA, reflecting that it needs to go through a few more steps to become an actual messenger RNA (mRNA). These are:

<u>Capping: </u>mRNA capping happens at the 5' end of the mRNA, usually adds metjyguanosine after RNA polymerase makes the 5' end of the primary transcript

<u>Polyadenylatio:</u>Addition of a poly-A tail (tail of A nucleotides) to the 3' end of the RNA

<u>Intron splicing:</u>Chopping out of introns, or "junk" sequences, and pasting together of the remaining, good sequences (exons)

Once it's completed these steps, the RNA is a mature mRNA. It can travel out of the nucleus and be used to make a protein.
