Collin often experiences a runner's high during his daily 3-mile run. This is most likely produced by neurotransmitters in his brain called endorphins.

Endorphins: They are the neurotransmitters or peptide hormones released in the brain and nervous system when exposed to some stress or intensive exercises.

They are often released in the brain to help relieve pain, reduce stress, and improve the sense of well-being. They are the kind of neurotransmitters that attach to opioid receptors in the brain and carry signals across the nervous system. They work by blocking the nerve cells that receive the pain signals.

People often feel a "runner's high" after a long run. Other forms of exercise can also help you to release endorphins and relieve pain. These include swimming, dancing, hiking, power walking, massage, etc.

To know more about endorphins, refer to the following link:

Compare and contrast polysaccharides and nucleic acids in terms of monomer diversity and how they monomers are joined together
harkovskaia [24]

The monomer units of the carbohydrates vary in their total numbers extensively. Moreover, positions of the carbonyl groups along with the orientation of the hydroxyl groups also vary in the carbohydrates' monomers. The presence of any modification is also variable.

On the other hand, the nucleic acids have only 4 monomeric units. The linkages between the nucleic acid residues have less geometry than the glycosidic linkages.

A geneticist isolates a gene for a specific trait under study She also isolates the corresponding mRNA Upon comparison, the mRNA
olga nikolaevna [1]

Answer:

C) no, the final mRNA contains only exons, the introns were removed

Explanation:

Exons are the coding areas while the introns are non-coding areas. Both of these are the sequences of nucleotide within a gene.

RNA splicing is a process which usually occurs as the RNA matures, causing the removal of introns ( non coding areas of the RNA ) i-e they will not be expressed in the final messenger RNA, while exons continue to form covalent bonds with one another to form a  mature mRNA.

So in the given scenario, Upon comparison, the mRNA is found to contain 1,000 fewer bases than the DNA sequence because the introns were removed by RNA splicing.

Hence option C) no, the final mRNA contains only exons, the introns were removed is correct.
