Chronic injuries usually result from overusing one area of the body while playing a sport or exercising over a long period of time. Example: pain when performing an activity, a dull ache when at rest and swelling.
RNA splicing was first discovered in 1970s in viruses and subsequently in eukaryotes. Not long after, scientists discovered alternative patterns of pre-mRNA splicing that produced different mature mRNAs containing various combinations of exons from a single precursor mRNA. The first example of alternative splicing of a cellular gene in eukaryotes was identified in the IgM gene, a member of the immunoglobulin superfamily. Alternative splicing (AS) therefore is a process by which exons or portions of exons or noncoding regions within a pre-mRNA transcript are differentially joined or skipped, resulting in multiple protein isoforms being encoded by a single gene. This mechanism increases the informational diversity and functional capacity of a gene during post-transcriptional processing and provides an opportunity for gene regulation
Answer:
The correct option is d. confer passive immunity.
Explanation:
An antitoxin is an antibody formed in an organism in response to the presence of a bacterial toxin inside, which it can neutralize. We speak of passive immunity, when it is obtained by the passage of antibodies (antitoxins) to the individual in a natural or artificial way, having as main feature that it is short-lived, since they remains only until the transferred antibodies or lymphocytes disappear.
