Base substitutions, deletions, and insertions are the three different forms of DNA mutations.

A mutation is a long-lasting alteration to the DNA's nucleotide sequence that can occur during replication and/or recombination. Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.

Different Mutations

Base substitutions, deletions, and insertions are the three different forms of DNA mutations.

1. Base Replacements

Point mutations are single nucleotide replacements; you may recall the point mutation Glu ——-> Val is the culprit of sickle cell anemia. There are two types of point mutations, the most prevalent of which are.

Transition and Transversion.

lana [24]

Answer:

There are many features that make bacteria survive in harsh conditions. Bacteria are found almost everywhere. There are various types of features found in bacteria. They can survive in harsh conditions because of the energy-generating enzymes, protein synthesis mechanism, biodegradative enzymes, and cell membranes. This adaptation helps them to survive in extreme conditions.

Answer: Confirm the presence of alcohol in an individual.

All of the above

Determine the role that tolerance may play in a case.

Explanation:

The field sobriety test is a standard field test which is done by the police officer to determine whether the person suspected of impaired driving is intoxicated with drugs or alcohol. This confirms the presence of alcohol in an individual driver.

Metabolism is a process of conversion of complex food particles or drugs or alcohol into water soluble metabolites so that these can be excreted out from the body readily. The metabolism process deactivates the potent drug, it converts the drug into substances which can be used for producing energy for metabolic reactions. The ethyl alcohol is also converted into acetic acid which is less potent metabolite, which can be excreted out from the body.

A forensic toxicologists is a scientists who performs the laboratory based tasks for identify the origin and concentration of drugs. They also determine the conversion of drug into metabolites in the body. Such a scientists have no role in observing and determining the tolerance of drug in a particular case this is the role of forensic psychologists.
