What else can I help you with?
A string of triplets that specifies a particular protein?
A gene is the string of triplets that specifies a particular protein.
A group of DNA nucleotides that contains the information to produce a single protein is a?
A gene is the segment of DNA with the information for a protein/proteins.
Which best describes the relationship between genes and proteins?
Basically, one gene gives the instructions for making one protein. I'm not sure how much detail you want, here, but a gene is a segment of DNA and the sequence of bases in the DNA determine the sequence of amino acids that make up the protein.
What hormones regulate protein synthesis?
Steroid hormones pass through the cell membrane and bind to a specific steroid hormone receptor protein. The combined steroid and receptor protein then bind to a specific sequence of bases in the DNA molecule. This sequence of bases is part of the promotor of a gene. Binding of the steroid - receptor complex either activates (switches on) or represses (switches off) the gene which is controlled by that promotor. If the gene is switched on then it will produce mRNA (transcription) which will lead to the sysnthesis of protein (translation). If the gene is switched off then mRNA will not be produced and no protein will be synthesised. In summary, steroid hormones can act to operate 'switches' for genes, switching protein synthesis on or off.

Through gene expression the messages encoded in the DNA contained in a cell direct the cells activity Which of the following sentences best defines gene expression?
Gene expression is the activation of a gene that results in the formation of a protein.
A typical gene consists of regulatory sites?
A typical gene consists of regulatory sites such as promoters and enhancers, which dictate when and how much the gene is expressed. These regulatory elements interact with transcription factors to control gene expression and play a critical role in determining the level of protein produced by the gene. Mutations in regulatory sites can lead to dysregulation of gene expression, causing disease.
What is difference between a structural gene and a nonstructural gene?
The difference between a structural gene and a nonstructural gene can be explained that structural gene is a gene encoding the amino acid sequence of a protein. Non-regulatory gene. A structural gene is a gene that codes for any RNA or protein product other than a regulatory element (i.e. regulatory protein)and then it makes proteins in the cell. However, the nonstructural gene is different from structure gene, for example (nonstructural gene)NS1 Influenza Protein is created by the internal protein encoding, linear negative-sense, single stranded RNA, NS gene segment; which found in Influenzavirus A, Influenzavirus B and Influenzavirus C;
In the control of gene expression in bacteria a regulatory gene a has its own promoter?
The regulatory gene a has its own promoter to enable transcription of the gene. This promoter allows for the synthesis of the regulatory protein encoded by gene a, which can then regulate the expression of target genes in response to specific signals or conditions in the bacterial cell. By controlling the production of this regulatory protein, bacteria can fine-tune their gene expression patterns for adaptation and survival.
The operon segment composed of the gene that codes for a protein repressor is called the?
The operon segment composed of the gene that codes for a protein repressor is called the regulatory gene. This gene produces the repressor protein that can bind to the operator region of the operon, preventing transcription of the structural genes when the repressor is bound.
What happens when there are changes in a gene?
The protein that the gene codes for changes or may even cease to be produced, depending on the change to the gene.
How is protein synthesis related to gene expression?
Protein synthesis is the process where proteins are produced based on the information encoded in genes. Gene expression involves the process where the information in a gene is used to produce a functional product, such as a protein. Protein synthesis is a key component of gene expression, as it is the step where the genetic information in the gene is translated into a functional protein.
What is the relationship between a cognate protein and its corresponding gene in the process of protein synthesis?
A cognate protein is a protein that is produced by a gene with a matching sequence. In the process of protein synthesis, the gene serves as a template for the production of the cognate protein through transcription and translation. The gene provides the instructions for the sequence of amino acids that make up the protein, which is then synthesized by the cell.
What is the smallest segment of DNA needed to produce a polypeptide or protein?
The smallest segment of DNA needed to produce a polypeptide or protein is a gene. A gene contains the instructions for making a specific protein through the process of transcription and translation. The gene includes sequences that code for the protein as well as regulatory regions that control its expression.
Each gene is composed of a regulatory chemical called?
Each gene is composed of a regulatory chemical called DNA. DNA contains the instructions for making proteins, which are essential for various functions in the body. The sequence of DNA within a gene determines the specific protein it will produce.
Can a mutation cause a protein to be overexpressed?
Yes, mutations can potentially lead to overexpression of a protein by altering the regulation of gene expression or by affecting the stability of the protein. Mutations that occur in the regulatory regions of a gene can disrupt the normal control mechanisms, resulting in increased production of the protein.
Why do the introns have to br removed?
Introns are the non-coding parts of the gene. If you didn't remove introns, the wrong protein may be produced because they allow more than one protein to be produced from a single gene.
What protein is produced when gene is activated through transcription and translation?
The protein coded for in the DNA transcribed ad then translated.
