When the adhesin gene of Neisseria gonorrhoeae were mutated, the pathogen will be unable to attach to the host cells.
<h3>What do you mean by Pathogens?</h3>
Pathogens may be defined as disease-causing agents. These are mostly microorganisms that infect the body of animals as well as humans.
Adhesin gene plays a very vital role in the attachment of pathogens to the host cells. It is the site where pathogen attack and attaches to host cells and then enters the body to play their function i.e. replication, a decline in the host immune system, and finally disease caused.
Therefore, when the adhesin gene of Neisseria gonorrhoeae were mutated, the pathogen will be unable to attach to the host cells.

Answer: Option (3) is the correct answer.
Explanation:
When a linear chain of carbon and hydrogen atoms is attached by single bonds only then it is known as alkane.
When a linear chain of carbon and hydrogen atoms contains a double bond then it is known as alkene.
When a linear chain of carbon and hydrogen atoms contains a triple bond then it is known as alkyne.
Therefore, in the given description there is a double bond between third and fourth carbon. Hence, the IUPAC name of given compound is 3-heptene.
Yes it is always changing, as time moves on new technological advancements are made. This makes it possible for new ideas to be created. For example the depiction of an atom went through many stages throughout the years in order to find out our current final version. New scientists and new ideas can add on to older ones, making explanations that make more scientific sense.
In SN1 reaction, the products will be formed as a racemic mixture.
<h3>What is racemic mixture?</h3>
Racemic mixture also called racemate, a mixture of equal quantities of two enantiomers, or substances that have dissymmetric molecular structures that are mirror images of one another.
<h3>What is SN1 reaction?</h3>
SN1 reaction corresponds to unimolecular nucleophilic substitution reaction. The order of reaction is one. The hydrolysis of tert-butyl bromide with aqueous NaOH solution is an example of SN1 reaction.
<h3>Why in SN1 reaction products will be formed as a racemic mixture?</h3>
The carbocation and its substituents are all in the same plane, meaning that the nucleophile can attack from either side. As a result, both enantiomers are formed in an the SN1 reaction, leading to a racemic mixture of both enantiomers.
