The Proteinaceous structure of the virus can mutate over time and lead to the development of new strains.
<h3>What is Mutation?</h3>
The mutation may be defined as the phenomenon of altering the sudden, stable, and inheritable genomic sequences of the organisms.
The outer layer of the virus is made of proteins and is hence known as a capsid. This layer is responsible for the allocation of mutations over time and leads to the development of new strains with respect to protein structures.
The changes in protein structures alter the whole physiology, metabolic, and anatomy of viruses accordingly.
Therefore, it is well described above.

<span>The answer is:
Penicillin was so heavily prescribed by doctors that it led to certain, more fit, strains of bacteria to be able to survive.

Okay, I can't upload a picture (my phone is broken so I'll try to explain the answer for problem number 7. Here you go: top left box EE, top right box Ee, bottom left box Ee, bottom right box ee. Also, you know to add two capital E's on top of the two top boxes like in the example for problem number 9 it has two lowercase n's (I hope I explained that in a way you can understand). on the left side of the top and bottom boxes, you should have E (top) and e (bottom). Draw it and I can tell you if it's correct.
RNA nucleotides have a uracil base instead of thymine.
