How can a chromosomal rearrangement cause an increase in the expression level of a gene?
The gene could be moved behind a stronger promoter, the gene could be duplicated, occasionally changes in the 3' and 5' UTRs can result in increased mRNA stability. Chromosomal rearrangement could also influence levels of enhancers and repressors.
What is meant by gene knockout testing?
Gene knockout testing is a technique used to study the function of a specific gene by inactivating or "knocking out" the gene from an organism's genome. This is typically achieved through genetic engineering methods such as CRISPR-Cas9 to create organisms that lack the target gene. By observing the effects of the gene knockout on the organism, researchers can learn more about the gene's normal function and its role in biological processes.
What is the normal function of the retinal blastoma gene?
tumor suppresser gene which codes for a protein that regulates E2F protein which is a cell cycle controller
Molecules that interact with DNA to alter gene expression are?
Transcription factors are molecules that interact with DNA to regulate gene expression by binding to specific DNA sequences. These proteins can promote or repress the transcription of target genes by influencing the recruitment of the transcriptional machinery. Additionally, epigenetic modifications, such as DNA methylation and histone acetylation, can also alter gene expression by affecting the accessibility of the DNA to transcription factors and RNA polymerase.
How are the knockout mice useful in determining the function of genes?
Knock out mice are produced by impairing or deleting a particular gene expression. Thus the gene function (which was deleted) can be tracked by studying this knock out and the control mice. Lets say a gene is suspected to trigger immune response against a pathogen, one can study this by infecting the wild type(normal) and knock out(specific gene deleted) mice and study the role of the gene.
When lactose is present in bacterial cell's it prevents the blocking effect of the repress or protein and allows the transcription of lactose metabolizing gene true or false?
false
What is the past tense of repress?
The past tense of repress is repressed.
When was The Private Repress created?
The Private Repress was created in 2003.
What is the definition of microbial genetics?
it is the study of gene and gene function in micro organisms.
What is the role of transcription factors in regulating gene expression by binding to enhancers?
Transcription factors are proteins that control the activity of genes by binding to enhancers, which are specific DNA sequences that enhance gene expression. By binding to enhancers, transcription factors can either activate or repress the transcription of genes, thereby regulating gene expression.
A sentence with the word repress?
When Aurora saw the A on her history paper, she couldn't repress her delight.
How is it possible for a point mutation to have no effect on the function of gene?
If the point mutation does not change the protein to be translated in the 3-letter sequence, then it will have no effect on the gene's function.
Who determines gene function?
genetic engineer
How does a somatic mutation in a gene alter the function of a cell?
A somatic mutation in a gene can alter the function of a cell by changing the instructions encoded in the gene, leading to abnormal protein production or function. This can disrupt normal cellular processes and potentially contribute to diseases like cancer.
What is null allele?
A null allele is a mutant copy of gene that completely lacks that gene's normal function. This can be the result of the complete absence of the gene product (protein, RNA) at the molecular level, or the expression of a non-functional gene product. At the Phenotypic level, a null allele is indistinguishable from a deletion of the entire locus.
What is an antimorph?
An antimorph is a gain of function mutation which acts in opposition to the normal gene's function.
What is the the function of a vertabrate?
Assuming you mean vertebrate and not vertabrate, its function is to propagate its gene line.
