What is the attachment site for RNA polymerase?
according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA. The factor 'sigma' will only attach itself to the complex DNA / RNA polymerase when the RNA polymerase is attached to a promoter. Another hypothesis is that the factor sigma attaches to RNApol anyway and the enzyme is then able to slide along the DNA until it finds a promoter. It prevents detaching and speeds up promoter location, and decreases the affinity of RNApol for general regions of DNA. " Therefore, the answer seems to be, RNA attaches to DNA through a small protein called the factor sigma once the RNA polymerase attaches itself to a chain sequence called a "promoter". according to information from http://www.rothamsted.ac.uk/notebook/courses/guide/trans.htm " if the RNA polymerase attaches to a special sequence called a promoter, an additional small protein, the factor sigma, will also attach to the polymerase and lock it on the DNA.

Actually there are many promoter and many genes but which gene to be transcribed is decided by sigma factor.
What attaches to DNA to start the process of transcription?
RNA polymerase attaches to specific regions of DNA called promoters to initiate the process of transcription. This enzyme unwinds the DNA double helix and synthesizes a complementary RNA molecule based on the nucleotide sequence of the DNA template strand.
What must happen to a DNA molecule before RNA polymerase can make RNA?
The DNA molecule must first unwind and separate into two strands. This process is called transcription, during which RNA polymerase can then read and transcribe one of the DNA strands to synthesize RNA.
How is DNA transcribed into RNA?
During transcription, the enzyme RNA polymerase binds to a specific region of DNA called the promoter. The DNA double helix unwinds, and RNA polymerase reads the DNA template strand and synthesizes a complementary RNA strand by adding nucleotides. This process continues until a termination signal is reached, resulting in the formation of a single-stranded RNA molecule that is complementary to the DNA template.
What is theProcess by which a molicule of DNA is copied into a stran of rna?
The process by which a molecule of DNA is copied into a strand of RNA is called transcription. During transcription, the enzyme RNA polymerase binds to a specific region of DNA called the promoter, unwinds the DNA strand, and synthesizes a complementary RNA molecule using one of the DNA strands as a template. This results in the formation of messenger RNA (mRNA), which carries the genetic information from DNA to the ribosomes for protein synthesis.

What is the process called that involves RNA polymerase?
The process is called transcription. In transcription, RNA polymerase synthesizes a complementary RNA molecule based on a DNA template.
What is an enzyme that attaches a phosphate group to another molecule is called?
A kinase is an enzyme that attaches a phosphate group to another molecule through a process known as phosphorylation.
The location where DNA polymerase attaches to the DNA strand?
DNA polymerase attaches to the DNA strand at a specific region called the origin of replication. This is where the double-stranded DNA is unwound, creating two template strands for DNA synthesis to occur. DNA polymerase then begins replicating the DNA in a 5' to 3' direction.
An enzyme that attaches a phosphate group to another molecule is called a?
kinase
What attaches to DNA to start the process of transcription?
RNA polymerase attaches to specific regions of DNA called promoters to initiate the process of transcription. This enzyme unwinds the DNA double helix and synthesizes a complementary RNA molecule based on the nucleotide sequence of the DNA template strand.
What happens during the transcription of a given portion of a DNA molecule?
During transcription, an enzyme called RNA polymerase binds to the promoter region of the DNA molecule. The polymerase then unwinds the DNA double helix and synthesizes a complementary RNA strand using one of the DNA strands as a template. This process results in the formation of a single-stranded RNA molecule that carries the genetic information encoded within the DNA onto mRNA.
What is the reaction called that attaches fatty acids tails together?
The reaction that attaches fatty acid tails together is called esterification. Esterification involves a condensation reaction between a carboxylic acid group of one fatty acid and an alcohol group of another fatty acid to form an ester bond, resulting in the formation of a lipid molecule.
Where does transcription being in DNA?
Transcription begins in the nucleus of a cell, where the DNA molecule unwinds and the enzyme RNA polymerase binds to a specific region of the DNA called the promoter. RNA polymerase then synthesizes a copy of the DNA sequence into a messenger RNA molecule.
What process results in the formation of an mrna molecule?
The formation of an mRNA molecule occurs through a process called transcription. During transcription, the enzyme RNA polymerase binds to a specific region of DNA and synthesizes a complementary strand of RNA by reading the DNA template strand. This newly formed mRNA strand undergoes processing, which includes capping, polyadenylation, and splicing, before it is transported out of the nucleus for translation into a protein.
What must happen to a DNA molecule before RNA polymerase can make RNA?
The DNA molecule must first unwind and separate into two strands. This process is called transcription, during which RNA polymerase can then read and transcribe one of the DNA strands to synthesize RNA.
When transcription begins the enzyme is called?
the RNA polymerase attaches to the promoter and transcribes the gene in messenger RNA, or mRNA
