Eukaryotic transcripts (mRNA) have to undergo capping and splicing before it can be translated.
<h3>RNA processing:</h3>
1. An RNA transcript is first produced in a eukaryotic cell as a pre-mRNA, which needs to be converted into a messenger RNA (mRNA).
2. The RNA transcript is given a 5' cap at the start and a 3' poly-A tail at the end.
3. The process of splicing involves cutting out some RNA transcript segments (introns), then joining the remaining segments (exons) back together.
4. Some genes have the ability to alternate splices, which produces various mature mRNA molecules from the same beginning transcript.
The introns not only do not contain the information necessary to construct a protein, but they also need to be cut off in order for the mRNA to create a protein with the correct sequence. An mRNA with extra "junk" in it will be created if the spliceosome fails to remove an intron, and the translation process will result in the production of the incorrect protein.

Answer:
False
Explanation:
Correct answer would be Exocytosis. Here's how to remember...
EXOcytosis = EXIT
ENDocytosis = ENTER

Answer: The producers refers to green plants that carry out the process of photosynthesis in order to produce food for themselves and others. The principal function of producers is to manufacture food for themselves and all other living organisms.
The consumers refers to those living organisms that can not produce their own food and have to depend on the food produce by others. Consumers can be categorized into primary, secondary and tertiary consumers depending on where they are located on the trophic levels. They can also be classified as herbivores, carnivores and omnivores depending on the type of food they eat. The major function of consumers is transference of energy. Consumers transfer the energy they obtain from the food they eat to those animals that feed on them.
The decomposers are those micro organisms that are majorly found in soils.The principal function of decomposers is to break down dead organic matters so that they can be absorbed by the roots of plants. The broken down organic substances serve as nutrients, which the plants used to grow and develop.
These three types of organisms work together in the ecosystem to maintain the balance of the ecosystem.
