Ne4ueva [31]3 years ago

The correct answer is: introns

Processing of mRNA is process that occurs only in eukaryotic cells. After the transcription, newly formed mRNA molecule is called and it must be processed into a messenger RNA (mRNA). Processing includes:

• Addition of a 5' cap to the beginning of the RNA

• Polyadenilation- addition of a poly-A tail (tail of A nucleotides) to the end of the RNA

• Splicing- removal of introns and linking the exons

After these steps mRNA is mature and used for the further steps (e.g. translation).

Sometimes some genes are alternatively spliced.

Answer:

Biome 1: Arctic Tundra

Organism 1: Arctic Fox

Explanation:

1. This organism can be found in a cold, snowy ecosystem with long winters and short summers.

How is it possible that functionally infinite variations of antibodies can be made from one set of genes?
Degger [83]
The practically boundless varieties of antibodies can be produced using one arrangement of qualities is introns and exons take into account one quality coding to really code for a wide range of antibodies. Amid the procedure of RNA grafting, introns are evacuated and exons joined to frame a bordering coding succession.
