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.
Answer: Self awareness
Explanation:
Drinking alcohol and using drugs are common means used by the people to escape from self awareness. One cannot be conscious after drinking alcohol or taking drugs.
If someone does not wants to face the reality and live in his virtual world then he should drink alcohol and take drugs.
The self awareness makes the person realize what he is doing is right or not but due to the effect of alcohol there is no self realization.
Answer: A. It is liquid and weighs two pounds.
Explanation:
A provides the most details and includes a quantitative measurement however an actual cup of gasoline does not weigh 2 pounds.
