Answer:

The correct answer would be 5' capping, 3' polyadenylation , and intron splicing.

In eukaryotes, transcription results in the formation of pre-mRNA which needs to be processed in order to become mRNA (messenger ribonucleotide).

The pre-mRNA processing include:

  • Addition of 5'cap (usually modified guanine nucleotide) at the 5'-end of the RNA. It prevents the RNA degradation and also help in the attachment of ribosome for translation.
  • Addition poly-adenine (poly-A) tail at the 3'-end of the RNA. It increases the stability of the RNA and helps in its export out of the nucleus.
  • Lastly, splicing takes place which removes the introns and joins the exons. Alternative splicing can also take place in order to produce many mRNA from a single gene.

How was the knowledge of ecological succession applied to the reclamation of land damaged due to mining?
Mandarinka [93]

After mining, to reclaim the land, the depression is filled with rocks then the top is filled with loosely graded soil. Introduction of early succession plants is important before big trees can grow. The early succession plants help in the breaking down of the rocks into soil hence making the topsoil deeper to support trees.

How genetic variations in a population increase some individual’s probability of surviving and reproducing in a specific environ
Keith_Richards [23]

Answer:

Any population in a given environment contains a variety of available, inheritable genetic traits. ... In a population, there is a cause-and-effect relationship between the variation of traits and the probability that specific organisms will be able to survive and reproduce.
