What would be the resulting strand of mRNA?

The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule. Figure 1: A gene is expressed through the processes of transcription and translation.

What strand is mRNA transcribed?

Visualizing Transcription 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.

What would be transcribed into mRNA?

Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). This complex initiates transcription, and the RNA polymerase begins mRNA synthesis by matching complementary bases to the original DNA strand.

How does RNA know which strand to transcribe?

RNA polymerase binds to the promoter, which orients it on the correct strand and in the correct direction, after which it can proceed to transcribe the gene.

Is the coding strand transcribed?

2.3 RNA Synthesis is Gene Transcription During transcription, the coding strand of DNA serves as a template for synthesis of a complementary RNA molecule. The sequence of the RNA molecule is determined by complementary-base pairing so that the RNA is a complementary transcript (copy) of the coding strand of DNA.

How is RNA transcribed?

It involves copying a gene’s DNA sequence to make an RNA molecule. Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template). Transcription is controlled separately for each gene in your genome.

How do you know which strand is the template strand?

The template strand is one of the DNA strands whose base sequence helps in building mRNA through complementary base sequencing. Template strand or “Antisense strand” runs in 3′- 5′ direction, opposite to the coding strand.

What is the DNA strand that corresponds to mRNA?

The DNA strand that corresponds to the mRNA is called the coding strand. The objective of transcription is to make a copy of RNA from the DNA sequence. The RNA transcript carries the information which is then used to encode a protein. Transcription takes place in three distinct steps.

How many strands of DNA are copied during transcription?

During the process of transcription, only one strand of DNA is copied. This strand undergoing the process is known as the template strand. The RNA molecules thus produced are single-stranded RNA called the messenger RNA or mRNA. The DNA strand that corresponds to the mRNA is called the coding strand.

How is information transferred from DNA to mRNA?

In the first step, the information in DNA is transferred to a messenger RNA ( mRNA) molecule by way of a process called transcription.

Why are RNA molecules released from DNA template as single strands?

Instead, just behind the region where the ribonucleotides are being added, the RNA chain is displaced and the DNA helix re-forms. Thus, the RNA molecules produced by transcription are released from the DNA template as single strands.
