Classify each description as true of introns only, exons only, or both.A-present in eukaryotic genomesB-generally absent from ba

maxonik [38]

The right answers are:

A-present in eukaryotic genomes ==> Both exons and introns

B-generally absent from bacterial genomes ==> Introns

C-part of the final mRNA strand ==> Exons

D-code for an amino acid sequence ==> Exons

E-removed from initial mRNA strand prior to translation ==> Introns

F-present in the DNA used as the template for transcription ==> Both exons and introns

In the genes of eukaryotic organisms, the exons are the segments of an RNA precursor that are conserved in the RNA after splicing and that are found in mature RNA in the cytoplasm. The segments of the RNA precursor that are removed during splicing are called in opposition to introns. Exons are mainly found in messenger RNAs (mRNAs) encoding proteins. Some mRNAs may sometimes undergo an alternative splicing process in which one or more exons may be excised or some introns preserved in rare cases.

Not one of the ways that bacteria have adapted to become resistant to antimicrobial agents.

Dominik [7]

Answer:

Explanation:

An antimicrobial agent is a natural or synthetic chemical that kills or inhibits the growth of microorganisms. Bacteria have a mechanism of transferring genomic material called horizontal gene transfer, the movement of genes between cells that are not direct descendants of one another. Horizontal gene transfer allows cells to quickly acquire new characteristics and drives metabolic diversity. One of the characteristics usually acquired is the resistance to antibiotics.

Three mechanisms of genetic exchange are known in prokaryotes:

(1) transformation, in which free DNA released from one cell is taken up by another; (2) transduction, in which DNA transfer is mediated by a virus; and (3) conjugation, in which DNA transfer requires cell-to-cell contact and a conjugative plasmid in the donor cell.

Examples of genes transferred by transducing bacteriophages include multiple antibiotic resistance genes among strains of Salmonella enterica serovar Typhimurium, Shiga-like toxin genes in Escherichia coli, virulence factors in Vibrio cholerae, and genes encoding photosynthetic proteins in cyanobacteria.

Conjugative plasmids use a mechanism to transfer copies of themselves and the genes they encode, such as those for antibiotic resistance, to new host cells.
