Classify each RNA post-transcription processing event according to whether it occurs in prokaryotes or eukaryotes.
tigry1 [53]

'RNA is transcribed and translated in the cytoplasm', 'transcription produces an mRNA ready for translation' and 'RNA is proofread for errors' occur in prokaryotes, whereas '5′ cap, 3' poly-(A) tail and RNA splicing' occur in eukaryotes.

The prokaryotic cells (e.g., bacterial cells) do not contain cell nuclei, thereby the messenger RNA (mRNA) must be transcribed and translated in the cytoplasm.

During prokaryotic transcription, the RNA transcript is proofread for errors. In bacteria, DNA polymerases proofread the transcript by using their 3’ → 5’ exonuclease activity.

In eukaryotic cells, RNA processing consists of several mechanisms:

  • A 7-methylguanosine cap (5′ cap) is added to the 5′ end of the precursor messenger RNA (pre-mRNA).

  • A 3' poly-Adenine (A) tail is added to the 3' end of the pre-mRNA.

  • Both the 5′ cap and 3' poly-(A) tail protect the RNA transcript from its degradation by exonucleases.

  • Eukaryotic RNA splicing consists of the removal of non-coding regions called 'introns' and subsequent splicing of the protein-coding regions called 'exons'.

Assess the effect of selective breeding on food crops.
fomenos
Selective breeding on food crops may create stronger, and more healthy crops. The idea is to find your best crops, and breed them with other crops sharing the traits you want. Selective breeding can make crops produce more matter that is edible, grow taller, grow shorter, etc.. W<span>eaker crops, or crops that have undesirable traits will slowly disappear, and eventually the gene pool will mostly have the selected crop</span>
