When does the most important step in gene regulation occur?
The most important step in gene regulation typically occurs during transcription, where RNA polymerase binds to the promoter region of a gene to initiate the synthesis of messenger RNA (mRNA). This step determines whether a gene will be expressed or not, and is crucial for controlling the levels of gene expression within a cell.
Is an expressed gene turned off?
No. If a gene is expressed, it is turned on.
How is the type of cell into which a new gene is inserted important in gene therapy?
The type of cell is important because it determines how the gene will be expressed and whether the inserted gene will function properly. Different cell types have different mechanisms for processing and utilizing genetic material, so selecting the correct cell type is crucial for a successful outcome in gene therapy. Additionally, the choice of cell type can impact the distribution and longevity of gene expression in the body.
Which parts of a gene are expressed as protein?
Coding sequences of a gene are expressed as protein
An expressed gene is one that what?
a gene being expressed means it is shown, for example if you have the gene for brown eyes and the gene for blue eyes, only one can be expressed. if you have brown eyes that gene is expressed, if not the blue-eye gene is expressed.
What factor determines whether a particular phenotype occurs more frequent than others in certain population?
Gene frequency
What does it mean for a gene to be off?
How is a gene not expressed
What gene that is always expressed and will produce a trait?
The gene that is always expressed and will produces a trait is a genetic statistic. This statistic is what is created when the gene is dominant.
Can everyone smell asparagus in their pee?
No. Strangely enough it is a single gene that determines whether the asparagus produces smelly pee - so it is an inherited thing. Some people have the gene, some don't.
How does epistasis explain the coat color in a labrador retriever?
Epistasis explains coat color in Labrador Retrievers through interactions between different genes. Specifically, two genes are involved: one gene determines the pigment (black or brown), while another gene (the E gene) controls whether the pigment is expressed. If a dog has two recessive alleles for the E gene (ee), it will be yellow, regardless of the alleles for the pigment gene. Thus, the presence or absence of the E gene masks the effect of the pigment gene, illustrating epistasis in action.
A gene that is not expressed in the heterozygous condition is called?
A recessive gene.
Do alleles control phenotype?
Yes, alleles are variations of a gene that can affect the phenotype of an organism. The combination of alleles an individual carries determines specific traits or characteristics that are expressed.
