The pieces of a split gene in eukaryotes are called exons and introns. Exons are the coding regions that are expressed and ultimately translated into proteins, while introns are non-coding regions that are removed during mRNA processing to produce the final mRNA transcript.

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.
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.
How do eukaryotes cells regulate gene expression?
the molecules of the bolecules conjogulate with the dna polymers, which disattches with the conjolecules.
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 makes the beginning of a new gene on DNA in eukaryotes?
The beginning of a new gene on DNA in eukaryotes is marked by the promoter region, which is a specific sequence of nucleotides that initiates the process of transcription by binding to RNA polymerase. This binding signals the start of gene transcription, allowing the RNA polymerase to begin synthesizing a complementary RNA molecule from the DNA template.
In the binding of RNA polymerase to a gene requires the aid of a transcription factor?
Yes, transcription factors are proteins that help RNA polymerase bind to specific sites on the DNA, known as promoter regions, to initiate transcription of a gene. They help regulate gene expression by promoting or inhibiting the binding of RNA polymerase to the gene.
A general scheme for genetic engineering is?
obtain DNA with the desired gene, cut the DNA into pieces, copy the pieces of DNA, identify copies of the desired gene, and transfer the desired gene to the recipient organism. for Plato the answer is A. not B. C. or D.
In eukaryotes what is active transcription generally associated with?
Active transcription in eukaryotes is generally associated with the unwinding of DNA and the recruitment of RNA polymerase to transcribe a specific gene into messenger RNA (mRNA). This process involves the assembly of transcriptional machinery at the promoter region of the gene and the initiation of RNA synthesis.
