What else can I help you with?
What area of a gene carries the code used to make a protein?
The coding region of a gene that carries the instructions for making a protein is called the "coding sequence" or "exon." This segment of the gene is transcribed into a messenger RNA (mRNA) molecule, which is then translated by ribosomes into a specific protein.
Which method is utilized by eukaryotes to control their gene expression that is not used in bacteria?
Eukaryotes utilize mechanisms such as chromatin remodeling, alternative splicing, and RNA interference to regulate gene expression, which are not commonly used in bacteria. These mechanisms allow for more complex and nuanced control of gene expression in eukaryotic cells.
Which are used more often in prokaryotes and eukaryotes activators or repressors?
Both activators and repressors are used in both prokaryotes and eukaryotes to regulate gene expression. However, activators are more commonly used in eukaryotes, while repressors tend to be more prevalent in prokaryotes.
What is a cell making a copy of a gene called?
It is called gene replication or gene duplication.
How is protein synthesis different in prokaryotes and eurkaryotes?
One way that protein synthesis differs between prokaryotes and eukaryotes is that gene groups that produce proteins are organized into operons in prokaryotes, but they are not organized into operons in eukaryotes. Also, protein synthesis in eukaryotes involves more protein and is a more intricate process than in prokaryotes.
Why are most mutations in eukaryotes recessive?
Most mutations in eukaryotes are recessive because they typically involve changes in a single gene, and the presence of a normal copy of the gene can often mask the effects of the mutated gene. This means that the mutated gene is only expressed when both copies of the gene are mutated, resulting in a recessive trait.
What region of prokaryotic gene is analogous to the enhancer region of a eukaryotic gene?
In prokaryotes, the regulatory region of a gene where transcription factors bind to enhance gene expression is called the promoter region. While prokaryotes do not have enhancer regions like eukaryotes, they can have operator regions where repressor proteins bind to downregulate gene expression.
In eukaryotes gene expression is related to the coiling and uncoiling of what?
In eukaryotes, gene expression is related to the coiling and uncoiling of DNA around histone proteins, forming chromatin. When DNA is tightly coiled around histones, it is less accessible for transcription, leading to reduced gene expression. When DNA is unwound, gene expression is more likely to occur.
In a eukaryote what is a segment of a gene that codes for a protein?
A segment of a gene that codes for a protein is called an exon. Exons are the parts of a gene that are ultimately expressed as proteins after being transcribed and translated. They are interspersed with non-coding regions called introns.
What is the main purpose of gene regulation in eukaryotes?
The main purpose of gene regulation in eukaryotes is to control which genes are turned on or off in response to internal and external signals. This allows for precise control of gene expression, ensuring that the right genes are expressed at the right time and in the right amount for proper cell function and development.
What area of a gene carries the code used to make a protein?
The coding region of a gene that carries the instructions for making a protein is called the "coding sequence" or "exon." This segment of the gene is transcribed into a messenger RNA (mRNA) molecule, which is then translated by ribosomes into a specific protein.
What role do introns play in the gene expression process of eukaryotes?
Introns are non-coding sections of DNA that are removed during the process of gene expression in eukaryotes. They do not code for proteins but play a crucial role in regulating gene expression by affecting how the coding regions (exons) are spliced together. This process, known as alternative splicing, allows a single gene to produce multiple protein variants, increasing the diversity of proteins that can be produced from a single gene.
How do eukaryotes cells regulate gene expression?
the molecules of the bolecules conjogulate with the dna polymers, which disattches with the conjolecules.
Why do most mutations in eukaryotes exhibit a recessive inheritance pattern?
Most mutations in eukaryotes exhibit a recessive inheritance pattern because they typically involve changes in a single gene, and the presence of a normal copy of the gene can often mask the effects of the mutated gene. This means that individuals with one normal and one mutated copy of the gene will not show the effects of the mutation, leading to a recessive inheritance pattern.
Which method is utilized by eukaryotes to control their gene expression that is not used in bacteria?
Eukaryotes utilize mechanisms such as chromatin remodeling, alternative splicing, and RNA interference to regulate gene expression, which are not commonly used in bacteria. These mechanisms allow for more complex and nuanced control of gene expression in eukaryotic cells.
Which are used more often in prokaryotes and eukaryotes activators or repressors?
Both activators and repressors are used in both prokaryotes and eukaryotes to regulate gene expression. However, activators are more commonly used in eukaryotes, while repressors tend to be more prevalent in prokaryotes.
Why do eukaryotes have introns in their genetic material?
Eukaryotes have introns in their genetic material because they allow for alternative splicing, which enables a single gene to code for multiple proteins, increasing genetic diversity and complexity.
