does the presence of introns exons in eukaroytic cells provide more potentia diversity in gene products than is possible in pork
Leona [35]

Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.

Explanation:

DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.

<u>Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA.</u> In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).

In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.

Your left wrist is what anatomical direction from your left elbow?
Norma-Jean [14]

Answer:

The correct answer will be- distal

Explanation:

In anatomy, the anatomist defined the standard position and movement of the bones of the skeletal system by universal anatomical terminologies.

The directional position of the bones of arms and legs is represented by the proximal and distal plane.

The proximal direction represents the bone closest to the point of origin or reference while distal represents the bone closest to the farthest away from the reference.  Since the left wrist is farther from the reference or the elbow therefore, it is considered distal to the elbow.

Thus, distal is the correct answer.

mr Goodwill [35]

Answer:

It is true

Explanation:

Use the DNA for the identification of suspects, it has been classified among secretors and non-secretors. In the category of secretors are individuals whose body fluids can be classified, through the determination of their blood group, with saliva being the most suitable substance.

Non-secretors can be classified but blood particles cannot be detected in the fluids.
