What is the function of a consensus sequence in transcription initiation?

∙ 12y ago
Definition:Consensus sequences are the repeated nucleotide's sequence e.g TATA box,GC-rich region etc.
Function:And these sequences can be start,stop,promoters' attachment sequences,etc.
So they are the cis-acting elements of DNA,with which the trans-acting elements interact.

The correct sequence of the events of transcription is?
RNA polymerase reaches the beginning of a gene.
What is the function of the TATA box?
The TATA box assists in directing RNA polymerase II to the initiation site downstream on DNA. RNA polymerases bind to regions of DNA known as promoters. Promoter regions are comprised of the initiation site and numerous nucleotides upstream from the initiation site. The TATA box is necessary for transcription because RNA polymersase II cannot recognize the initiation sites on its own.
If a strand of DNA has the sequence aagctc transcription will result in?
If a strand of DNA has the sequence aagctc, transcription will result in a mRNA molecule with the complementary sequence uucgag. Transcription is the process of creating a mRNA molecule using DNA as a template.
What is transcription and what are the main steps involved in this process?
Do your own lab report. Jk. Transcription is the process in which DNA is converted into a complementary RNA. Before transcription, the splicing of introns has already occurred. Transcription takes place the nucleus. RNA polymerase begins the elongation of the RNA while the DNA template is unwound and rewound. Transcription responds to the termination signal and disassembles, terminating the process. The RNA is then processed with 5' G cap and poly A tail, and exits the nucleus, heading into the cytoplasm.
What amino acid would be produced if transcription took place from the DNA sequence CAT?
Transcription of the DNA sequence CAT would produce the messenger RNA sequence CAU. This mRNA sequence would then be translated by ribosomes to produce the amino acid histidine.
What event in transcription initiation likely occurs last?
The binding of RNA polymerase to the promoter sequence is the likely event that occurs last in transcription initiation. This binding allows for the initiation of RNA synthesis and the subsequent elongation of the RNA molecule.
The correct sequence of the events of transcription is?
RNA polymerase reaches the beginning of a gene.
What is initiation in transcription?
Initiation in transcription is the beginning stage where RNA polymerase binds to the promoter region of a gene and starts unwinding a section of DNA to synthesize a complementary RNA molecule. This process is crucial for the initiation of gene expression and the production of mRNA.
What is the function of the TATA box?
The TATA box assists in directing RNA polymerase II to the initiation site downstream on DNA. RNA polymerases bind to regions of DNA known as promoters. Promoter regions are comprised of the initiation site and numerous nucleotides upstream from the initiation site. The TATA box is necessary for transcription because RNA polymersase II cannot recognize the initiation sites on its own.
A DNA sequence that signals a gene's start is?
The DNA sequence that signals a gene's start is called a promoter region. This region is crucial for the initiation of transcription, where an enzyme called RNA polymerase binds to the promoter and begins the process of copying the gene into messenger RNA. Promoter regions are typically located near the gene's transcription start site.
What determines where on the DNA molecule transcription begins and ends?
Transcription begins at a specific DNA sequence called the promoter region, which signals the RNA polymerase enzyme where to start transcribing. Transcription ends at a specific DNA sequence called the terminator region, which signals the RNA polymerase to stop transcribing. These regions, along with other regulatory elements, help determine the initiation and termination points of transcription.
What is the name of the process whereby a DNA sequence is converted into a RNA sequence?
transcription
What refers to translating the sequence of nucleic acids to the sequence of amino acids?
Transcription.

The making of RNA based on the sequence of nucleotides in DNA is called?
The making of RNA based on the sequence of nucleotides in DNA is called transcription. During transcription, an enzyme called RNA polymerase binds to a specific region of DNA, called a promoter, and synthesizes a complementary RNA molecule using one of the DNA strands as a template.
If a strand of DNA has the sequence aagctc transcription will result in?
If a strand of DNA has the sequence aagctc, transcription will result in a mRNA molecule with the complementary sequence uucgag. Transcription is the process of creating a mRNA molecule using DNA as a template.
Rna molecules are produced by copying part of the nucleotide sequence of DNA into a complementary sequence in rna?
transcription
