Is the promoter found on coding or template strand?
Promoters are about 100-1000 base pairs long and are adjacent and typically upstream (5′) of the sense or coding strand of the transcribed gene.
Is the terminator on the coding strand?
It is a DNA sequence that provides a binding site for RNA polymerase. On the contrary, the terminator is located towards the 3-end of the coding strand and it usually defines the end of the process of transcription.
Is the promoter on the top or bottom strand?
The bottom strand is used as a template for transcription, thus containing the promoter region. RNA polymerase binds at the promoter and moves forward. RNA can be made only in the 5′ to 3′ direction, antiparallel and complementary to the template.
What are the template and coding strands of DNA?
DNA is double-stranded, but only one strand serves as a template for transcription at any given time. This template strand is called the noncoding strand. The nontemplate strand is referred to as the coding strand because its sequence will be the same as that of the new RNA molecule.
In which Strand is promoter present?
sense strand
Promoters are located near the transcription start sites of genes, upstream on the DNA (towards the 5′ region of the sense strand).
Is promoter on both strands?
The promoter will be a double stranded sequence at the end of the gene where RNA polymerase starts (= on 3′ end of template strand = on 5′ end of sense strand). Going along the sense strand, the way the gene is usually written (5′ to 3′, left to right) the promoter is “upstream” of the gene.
What strand is the promoter located on?
The promoter will be a double stranded sequence at the end of the gene where RNA polymerase starts (= on 3′ end of template strand = on 5′ end of sense strand). Going along the sense strand, the way the gene is usually written (5′ to 3′, left to right) the promoter is “upstream” of the gene.
What is the difference between the coding strand and template strand?
The key difference between these two strands is that template strand possesses the opposite base sequence of RNA while coding strand possesses the same base sequence of RNA (with the exception of thymine instead uracil). Not all DNA strands in a cell are transcribed into RNA.
