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.

allochka39001 [22]

Answer:

The correct answer is - c) Pathology.

Explanation:

Mycology is the branch of biology in which students study fungi and their characteristics including their biochemistry, taxonomy, and genetics.

Agronomy is the other branch of biology that deals with agriculture and its practices and work to improve the crops.

Phycology is the study of algae and their characteristics including their biochemistry, taxonomy, and genetics.

The disease and its causes are studied under the pathology branch o  biology therefore, red rust would be studying in this discipline.

Explain ​how​ scientists got the space station up in space. What ​problem​ did they
natta225 [31]

Answer:

scientists got the space station up in space in to small pieces.

Explanation:

The main problem which was faced by the scientist was that there was no powerful rocket which has the ability to lift the whole space station due to its more weight and carry it to the space against the powerful force of gravity. So for solving this problem, space station is taken into pieces into the space and then these pieces should be join to build the space station.
