From Pollution you know smokes
In human gene therapy, a genetically modified virus (a.k.a. a viral vector) can alter the genetic variation of a cell, but not all viral vectors do.
The process often begins with the delivery of or creation of a segment of viral double stranded DNA (containing the gene you want to introduce). Then typically an enzyme known as an integrase cuts the ends of the segment of viral DNA and also cuts open the cell's DNA. Then the viral DNA is integrated/ inserted into the cell's DNA. The connecting ends are ligated together and adjusted so that the nucleotide base pairs match up.
This in the future may affect the gene pool for instance if the viral DNA (your gene) was inserted in the middle of another gene or important regulatory sequence of the cell DNA, and this alteration may be passed on into offspring and become present in the gene pool, which could have bad effects.
The effects on the gene pool really depends on what the virus ends up doing. For example, it may fix the function of a damaged gene which is the goal, and allow for a working gene to be in the gene pool, which would be good. The problem with gene therapy is that it's difficult to predict 100% what the virus will do every time it is given to a patient.
But it's very important to consider that it will only affect the gene pool if the virus is able to enter and alter germ cells (reproductive cells). If the virus, enters somatic cells (regular body cells) this will not be passed on to future generations. So viruses can be designed to avoid germ cells and avoid this gene pool issue. Also, some viral vectors use viruses that do not integrate their DNA, the cells just express the viral DNA (create the desired protein from it) and over time the viral DNA is degraded/ lost which wouldn't pose this threat.

T2 virus is also known as Enterobacteria phage T2. This virus is a bacteriophage, which means that infects and kills E. coli. It consists of DNA and protein: the genome is linear double-stranded DNA, with repeats at either end and the protective coat is protein.</span>
Answer:
Ego
Explanation:
In 1923, Sigmund Freud's personality theory was structured into three different parts viz: Id, ego and superego
The id is the instinctive and unconscious part of the personality which responds directly to urges, needs and desires. The id operates on the pleasure principle that every wishful impulse should be satiated instantly regardless of the resulting effect.
The ego is the part that mediates between the unreasonable id and societal beliefs. It is the reasoning and decision-making component of the psyche.
The superego is the part that acts as a self critical conscience, reflecting the social standards that has been learnt
In this scenario involving Cecil, the id part of his personality is responsible for the sexual attraction to his English teacher but the ego part of his personality is making him realize that is socially unreasonable for his teacher to respond to his sexual advances. His ego, which operates with the reality principle is restraining him from acting from his feelings in consideration of social realities.
Therefore, his ego is restraining him from expressing his feelings of sexual attraction (Id) considering societal consequences.
