What does transcribed mean in biology?
In biology, transcription is the process by which genetic information encoded in DNA is copied into RNA. This RNA molecule can then be used to produce proteins through a process called translation. Transcription is a crucial step in gene expression and is tightly regulated in cells.
What mechanisms are used to coordinately control the expression of multiple related gebes in eukaryoutic cells?
Eukaryotic cells use transcription factors, which are proteins that bind to specific DNA sequences, to coordinately control the expression of multiple related genes. These transcription factors can either activate or repress the expression of multiple genes at once through binding to common regulatory sequences, such as enhancers or silencers. Additionally, chromatin structure and modifications play a crucial role in regulating the accessibility of DNA to transcription factors and the transcription machinery.
What is a small section of a chromosome that controls the production of proteins called?
A small section of a chromosome that controls the production of proteins is called a gene. Genes contain the instructions for making specific proteins through a process called gene expression, which involves transcription and translation of the genetic information.
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.
The code for the synthesis of proteins is contained in?
The code for the synthesis of proteins is contained in the DNA molecule. Genes, which are specific sequences of DNA, provide the instructions for making proteins through the process of transcription and translation. During transcription, messenger RNA (mRNA) is synthesized from a gene. Then, during translation, the mRNA is used as a template to assemble a specific protein.
Do proteins code for genes in the process of genetic expression?
Yes, proteins do not code for genes in the process of genetic expression. Genes code for proteins through the process of transcription and translation.
What is a length of DNA that codes for a protein?
A length of DNA that codes for a protein is called a gene. Genes contain the instructions for making specific proteins through a process called gene expression. This process involves transcription of the gene into messenger RNA (mRNA) and translation of mRNA into protein.

How are cells able to produce the proteins required under specific conditions?
Cells are able to produce proteins required under specific conditions through a process called protein synthesis. This process involves the transcription of DNA into messenger RNA (mRNA) and the translation of mRNA into proteins by ribosomes. Cells can regulate protein production by controlling the expression of specific genes in response to external signals or environmental cues.

DNA passes information to RNA during what process?
Transcription. DNA serves as the template for the synthesis of RNA molecules through transcription. During transcription, the information encoded in the DNA is transcribed into a complementary RNA sequence by RNA polymerase.
What is a small section of a chromosome that controls the production of proteins called?
A small section of a chromosome that controls the production of proteins is called a gene. Genes contain the instructions for making specific proteins through a process called gene expression, which involves transcription and translation of the genetic information.
The process of making an RNA version of a gene is?
The process of making an RNA version of a gene is called transcription. During transcription, the DNA sequence of a gene is used as a template to synthesize a complementary RNA molecule. This RNA molecule can then be used to produce proteins through the process of translation.
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.
Do lipids control the activity of genes?
No, lipids do not directly control the activity of genes. Gene expression is primarily regulated by transcription factors and other proteins that bind to specific gene sequences. Lipids can influence gene expression indirectly through signaling pathways that affect gene transcription.
How do cells control gene expression?
The promoter allows the gene to be transcribed. It helps RNA polymerase find where a gene starts. An operator is a DNA segment that turns the gene "on" or "off." It interacts with proteins that increase the rate of transcription or block transcription from occurring.
The code for the synthesis of proteins is contained in?
The code for the synthesis of proteins is contained in the DNA molecule. Genes, which are specific sequences of DNA, provide the instructions for making proteins through the process of transcription and translation. During transcription, messenger RNA (mRNA) is synthesized from a gene. Then, during translation, the mRNA is used as a template to assemble a specific protein.
