Gene mutations can be positive, negative, or neutral. Suppose that the normal gene in Model 2 produced a polypeptide that was necessary for cellular respiration.

A) Choose a mutation from those in Model 2 that might be positive for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.

B) Choose a mutation from those in Model 2 that might be negative for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.

The abbreviation in the gene normal gene sequence that leads to the formation of abnormal protein is called genetic mutations.

The correct answer is all of them, the mutation can be positive, negative, and neutral. The solution is as follows.

The answer to the first question is as follows:-

Gene present in the DNA is responsible for the formation of the protein via a process called transcription.  The substance that is required for translation is mRNA, ribosome, and etc.

The process of formation for RNA from the DNA is called transcription.

A mutation is the abbreviation of the sequence of the normal DNA from the infected protein is called a mutation. The reason for the mutation is the addition, deletion, and insertion of the base pair.

The difference in the population is due to variation in the genes. The reason for the variation is cell division. The cell division leads to the mixing of a gene by the process of crossing over.  Crossing over occurs only in meiosis.

There are three types of mutation.

When mutation leads to the formation of a new character that helps in surviving in the environment is called positive mutations.

When mutation leads to the formation of a new character that does not help in surviving in the environment is called negative mutations.

When mutation does not have any effect on the gene and does not form any new character is called a neutral mutation.

The answer to the second question is as follows:-

During the metabolism, the errors of genes can lead to the formation of abnormal characters.

Gene mutations can be positive, negative, or neutral. Suppose that the normal gene in Model 2 produced a polypeptide that was necessary for cellular respiration.

A) Choose a mutation from those in Model 2 that might be positive for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.

Genes encoded in our DNA result in the production of proteins that perform specific functions  within human's cells and various environmental factors and spontaneous events can lead to changes in genes, these changes are called mutations, can lead to alterations in the structure and activity of the proteins in the cells use. Mutations are the source of all new alleles in nature and arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Therefore,a gene mutation is a change in the sequence of nucleotides that occurs during cell replication  (mitosis and meiosis) within a single coding section of DNA. Variations in alleles lead to variations in organisms  within a population, cellular respiration, i.e. the reduction of inspired oxygen to water, which powers cell function, also generates highly reactive oxygen species that can damage DNA, with the purine bases G and A being particularly susceptible to this kind of attack,so Positive mutations lead to the organism having a better chance of survival, which  means the mutation may be passed on to the offspring.

B) Choose a mutation from those in Model 2 that might be negative for a cell. Explain your reasoning by relating the mutation to the cellular respiration process.

Due to one's metabolism, the human body replaces every cell within the cellular respiration process and any mistakes can also occur in the  transcription of mRNA or the translation of a polypeptide. However, these changes are considered to be negative mutations, because they are not permanent changes to the cell, however such mutations may lead to an early death probably before the organism can produce offspring.
