What is a promoter in DNA?
A promoter is a sequence of nitrogenous bases in DNA that signals the enzyme complex "DNA-polymerase" to begin unwinding the gene to transcribe it. A promoter is usually referred to as a "TATA (thymine, adenine, thymine, adenine) box" or a "CAAT (cytosine, adenine, adenine, thymine) box". As DNA polymerase makes its way down a section of DNA and comes across TATA box, or a CAAT box, that is the signal to begin transcription.
Does transcription begin at a promoter region and continue until RNA polymerase reaches a stop codon?
yes,
What is first located on a gene?
A promoter <--- Gradpoint/NovaNet A promoter is located at the beginning of a gene. A promoter functions by facilitating transcription of that gene
What role do transcription factors play in cell?
By binding to a plasma membrane receptor it initiates a cascade in a signal transduction pathway. They can activate yet more genes.
What is the sequence of nucleotides on DNa to with ran polymerase will attach to start transcription?
A promoter is a segment of DNA that helps RNA polymerase recognize the start of a gene.
What is the name of the process where RNA codon is read and the tRNA anti-codon brings amino acids to the codon?
Transcription
What is the sequences in the?
RNA polymerase attaches and initiates transcription.
What is the function to stop a codon?
the stop codon uaa, uag, or uga triggers the ending of the transcription process
What process begins at the promoter of DNA?
The promoter is the sight at which the transcription machinery binds the DNA and initiates the transcription of the gene.
Does translation always begin with a AUG codon?
No, sometimes alternate translation starts at GUG.
What does AUG mean in biology?
AUG is a start codon. It starts transcription, which is the synthesis of mRNA
What code tells a cell to stop making a protein?
A codon at the end of RNA signals the end of transcription. This is encoded by the codon sequence UAA, UGA, or UAG.
What is non sense codon?
A nonsense codon is nucleotide triplet that does not code for an amino acid, but rather it promotes the stop of transcription. These codons include UAA, UGA, and UGA.

Why do promoters need to be transferred along with desired genes in gene technology?
to ensure the genes are identical
