The answer would be
older peopleshould be vaccinated because elderly individuals are more susceptable to diseases and proper vaccinations can help prevent this matter. some may even think the answer could be antibiotics but antibotics taken repetitively can lose its potency and the body will be immune to its once helpful purpose. hope this helped love
What is a virus ?
Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.
Answer:
<em>make a gene from the given mRNA without the introns.</em>
Explanation:
Introns can be described as the non- coding regions of DNA. As they are non- coding, they are spliced out from the mRNA so that only the coding regions can be translated.
If we know a nucleotide sequence, then we can make a gene from it without added the introns. We can consider an mRNA strand and make a complementary strand from it, excluding the intron regions. Then from the DNA produced, we can make an mRNA without the introns and insert it into a bacterium.
