The intron acting in this scenario is A carbohydrate. <u>Option A.</u>
<u />
The most important function of introns is to allow alternative splicing, allowing multiple proteins to be made from a single gene. Some introns are spliced and further processed to encode functional RNA molecules. The first stage is the genomic intron, which is the DNA sequence of the introns.
Introns are regions within a gene that do not remain in the final mature mRNA molecule after transcription of the gene and do not code for the amino acids that make up the protein encoded by that gene. Most protein-coding genes in the human genome consist of exons and introns. Introns are nucleotide sequences in DNA and RNA that do not directly code for proteins and are removed during mRNA maturation by RNA splicing during the precursor messenger RNA stage.
<span>The second statement is correct. Viruses can infect all cellular life forms, but each cellular species
can be infected by own limited specific range of viruses. Most viruses that harm
animals can not harm humans. But, some viruses can infect different species of mammals, for example both
bats and humans can be infected be rabies.</span>
