Answer:
Explanation:
Type of gene(s) found in cancer cells -------------- oncogene
type of gene(s) found in normal cells and cancer cells ----- oncogene, proto-oncogene
gene(s) that could code for a normal growth factor ---------------- proto-oncogene
gene(s) whose absence can cause cancer --------- tumor suppressor gene (anti-oncogene)
type of gene(s) found in normal cells ----------- oncogene and proto-oncogene
gene(s) whose presence can cause cancer ------------- oncogene
type of gene(s) found only in cancer cells ------- oncogene
Oncogene are the switch off of proto-oncogene and are responsible for abnormal cell growth. Oncogene are found in all normal cells. They are mutated proto-oncogene.
Answer: The claim that gene regulation results in differential gene expression and influences cellular products (albumin or crystalline) is best supported by t<u>he specific transcription factors made in a cell.</u>
Explanation:
Genes store deoxyribonucleic acid or DNA that makes up the genome. The genetic information within genes is expressed through a process called transcription followed by translation.
During this, the genotype of the organism is changed into its phenotype or physical characteristics genes are controlled or regulated through certain molecular mechanisms These essentially determine transcription and translation and whether gene products is active or in active genes are turned on when they are able to transcribe the genome.
gene expression may be regulated
via
- modulation before or after the transcription process
- modulating translation
- modulation after translation
A control for the transcription process is called a transcription factor. These are DNA sequence specific proteins that are capable of activating or suppressing transcription at certain sites. In different cell types, different combinations of transcription factors contribute to gene expression.
Fermentation is a metabolic process in which an organism converts a carbohydrate, such as starch or sugar, into an alcohol or an acid. For example, yeast performs fermentation to obtain energy by converting sugar into alcohol. Bacteria perform fermentation, converting carbohydrates into lactic acid
Answer:
a) Astrocytes
Explanation:
The astrocytes are components of the central nervous system that provide the necessary supports that the brain needs to perform vital tasks such as learning and other daily activities. They are typical cell types in the central nervous system that aid blood flow in the brain as well as the migration of neurons.
