Biology
1 answer:
cluponka [151]3 years ago
5 0

Answer: B) mRNA processing events that lead to different types of exons being spliced together

Explanation:

When DNA is transcribed into mRNA, a primary RNA or pre-mRNA transcript is obtained that includes introns and  exons. For this pre-mRNA to give way to an mRNA it must undergo a maturation process of the mRNA, which

is basically to eliminate all introns primary transcript and then binding exons.

So RNA splicing is a post-transcriptional process of maturing RNA from which certain sequential fragments are removed. This process is very common in eukaryotes, and can occur in any type of RNA, although it is more common in mRNA.

Removal of introns and binding of exons in the mRNA occurs before leaving the nucleus. This process is known as splicing. <u>The alternative splicing of identical RNA transcripts into different cell types can produce different molecules of mature mRNA that are translated into different polypeptides.</u>

Some of the potential side effects of steroids are that in males it can cause reduction in sperm count, and shrinkage of testicles. While in women, it can cause the growth of body hair and can reduce the size of breasts.

Diuretics help to reduce the amount of fluid in the blood vessels, which further helps to lower the blood pressure. Some of the side effects of diuretics are fatigue, muscle cramps, irregular heartbeat, dehydration, and even death.  

Creatine assists in making muscles to produce more ATP and delay muscle fatigue. Some of the side effects are stomach and muscle cramps, diarrhea, nausea, weight gain, and water retention.  

Stimulants help to reduce fatigue, better alertness and suppress appetite. Some of the side effects are nervousness, irritability, increased blood pressure, insomnia, hallucinations, and heart attack.  

Boron is used in the treatment of osteoarthritis, enhances the levels of testosterone, and for better muscle coordination and better-thinking skills. Some of the side effects of boron are diarrhea, dermatitis, discoloration of feces, vomiting, nausea, and upper abdominal pain.  

Vanadium is used to treat low blood sugar, diabetes, heart issue, high cholesterol, water retention, syphilis, and better athletic performance in weight training, and even prevents cancer. However, it can cause some side effects like green tongue, and diarrhea.
