A . mitosis
Explanation:
The cellular process that would be directly affected by this catalyst is the mitosis.
Mitosis is as form of cell division in body cells. It ensures that restores the number of chromosomes in the daughter cell.
- During mitosis, chromosomes are replicated and are facilitated by certain catalysts.
- If a catalyst blocks off the separation of chromosomes, the process of mitosis will be affected and might not occur.

Answer:
<h2>EGFR will activate other proteins without dimerization, causing uncontrolled cell growth.</h2>
Explanation:
EGFR gene
:
Epidermal growth factor receptor,
-which spans the cell membrane so that one end of the protein remains inside the cell and the other end located outer surface of the cell. This causes receptor to attach ligands, and to receive signals ,by which cell respond to its environment. Epidermal growth factor receptor binds to many different type of receptors. The binding of a ligand to receptor allows the receptor to attach to another nearby epidermal growth factor receptor protein (dimerize), activating the receptor complex. As a result, signaling pathways within the cell are triggered that promote cell growth and division and cell survival. If there is abnormlty in the expression of EGFR gene , then the cell show uncontrolled growth.
Explanation:
Genetic alternations include chromosomal abnormalities and gene mutations. Chromosomal abnormalities generally arise during cell division. ... Gene mutations are permanent changes in DNA gene sequence. They can arise during normal DNA replication or in response to environmental factors.
The answer is:
<span>processing of exons in mRNA that results in a single gene coding for multiple proteins.

RNA splicing is an important stage in gene transcription. mRNA transfers the information from DNA to proteins. In many cases, this process creates multiple proteins from the same gene by varying the exon composition. This is called alternative splicing and can happen because exons are extended or skipped, or introns can be retained instead of being removed.
Answer:
false
Explanation:
The scientific name of a species tells you the genus and the species name of an organism.
