Before leaving the nucleus, the pre-mRNA transcript formed through transcription undergoes a series of enzyme-regulated modifications. Part of the process is illustrated below. Without this modification, why would mRNA be translated into a nonfunctional protein?

Answers

Post transcription

Explanation:

Before leaving the nucleus, the pre-mRNA transcript formed through transcription undergoes a series of enzyme-regulated modifications which includes: 5'capping,splicing,3' cleavage(polyadenylation) and RNA editing

  • 5' capping is the first modification event in the pre mRNA that occurs after 20-30 nucleotide addition,in capping a 7 methyl guanosine(cap) is added to the 5' end of pre-mRNA
  • Splicing is the second modification event of pre-mRNA occurs in nucleus just after transcription but before the RNA moves to the cytoplasm
  • In RNA splicing non coding regions of pre-mRNA called introns are removed and coding regions called exons are religated
  • If this modification does not occur then introns will be copied from DNA that will interrupt the genetic code
  • Most of mature eukaryotic mRNA have 50-250 adenine residue at the 3'end called Poly A tail
  • These nucleotides are not encoded by the genome but are added after transcription,process is called polyadenylation
  • Polyadenylation is both template and primer independent process catalysed by polyadenylate polymerase and protects mRNA from exonuclease at 3'end
  • RNA editing is defined as the change of nucleotide sequence of RNA which is carried out in two different ways: site specific base modification and insertional or deletion type of RNA editing

Answer:

Introns are regions of pre-mRNA copied from DNA that interrupt the genetic code.

Explanation:

1. DNA is first transcribed into pre-mRNA, then this pre-mRNA further go series of modification, like 5' capping, 3' polyadenylation and RNA splicing.

2. Through splicing, introns are removed and exons are joined together to form a mature RNA known as mRNA.

3. If without these modifications, RNA is translated, it would encode non-functional protein because all the codons in the pre-mRNA would translated and introns would code a non-functional protein.

A puffy white cloud with a flat bottomA. Cumulus

B. Fog

C. Stratus

D. Cumulonimbus

Answers

The correct answer is Cumulus.

These clouds look puffy and is flat in bottom. They look like cauliflower and  are white colored too.

These forms of clouds floats in the sky and seems to be like floating cotton. They are located at 3300 feet above the ground.

They always grow in upward direction and can sometimes form giant structures which are known a the giant cumulonimbus which is responsible for thunderstorms.
The cloud is a cumulus cloud

What is the scientific definition of energy? A. the ability to use the stored potential of an object B. the ability to use the change in direction of an object C. the ability to use an applied force in order to make an object move D. the ability to use the change in temperature of an object

Answers

Correct answer: C). The ability to use an applied force in order to make an object move

The energy can be defined as the capacity to move an object by the application of the force. It can exist in various forms such as chemical, electrical, mechanical and nuclear. It can not be created but it can be transformed from one form to another form of energy. It is the driving force of the universe.

Hence, the correct answer would be option C.
the answer is C. The ability to use an applied force in order to make an object move.

b. desensitizing.
c. nurturing.
d. habituation.

Answers

The answer is option D. Habituation. Habituation is the process of filtering out sights, scents, and sounds that have little effect on survival. Habituation is the diminished response of animals to certain stimuli that are deemed unnecessary or irrelevant in the process of of survival.
