The human genome contains approximately 20,000 protein-coding genes, yet it has the capacity to produce several hundred thousand

gene products. What can account for the vast difference in gene number and product number? The human genome contains approximately 20,000 protein-coding genes, yet it has the capacity to produce several hundred thousand gene products. What can account for the vast difference in gene number and product number? Alternative splicing occurs. There are more introns than exons. There are more exons than introns. Much of the DNA is in the form of trinucleotide repeats, thus allowing multiple start sites for different genes. Every gene can be read in both directions, and each gene can have inversions and translocations.

Answer:

Alternative splicing occurs.

Explanation:

The human genome comprises of a large number of introns or no protein-coding sequence interspersed between the exons or the protein-coding sequence.

After transcription in eukaryotes, an event takes place called splicing which removes all the introns from the mRNA and joins exons and additionally alternative splicing takes place which joins together many exons in many combinations which produce a variety of processed mRNA and thus a variety of proteins.

The process of alternative splicing produces a lot more than proteins from a single gene product.

Thus, alternative splicing is correct.

Answer:

The correct answer is (b) epinephrine.

Explanation:

Epinephrine, also known as <em>Adrenaline</em>, is a hormone secreted by the medulla of the adrenal glands.

In medicine, epinephrine is used as a stimulant in cardiac arrest, as a vasoconstrictor in shock and as a bronchodilator and antispasmodic in bronchial asthma.

When epinephrine is inhaled in small doses, it causes short-term relief from the symptoms by widening the bronchial tubes allowing air to pass through.

I hope it helps!
