What best describes the process of transcription?

Key points: Transcription is the process in which a gene’s DNA sequence is copied (transcribed) to make an RNA molecule. RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule. Transcription ends in a process called termination.

What does the process of transcription occur?

Transcription takes place in the nucleus. It uses DNA as a template to make an RNA molecule. RNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. It is the transfer of genetic instructions in DNA to messenger RNA (mRNA).

Which process is part of transcription quizlet?

Transcription is the process of producing RNA and DNA and translation is the process by which polypeptides are assembled from the information encoded in mRNA. A codon is a series of three nucleotides in mRNA that code for a specific amino acid and an anticodon is a set of three bases complementary to the codon.

What is the main goal of transcription?

Overview of Transcription. Transcription uses the sequence of bases in a strand of DNA to make a complementary strand of mRNA. Triplets are groups of three successive nucleotide bases in DNA. Codons are complementary groups of bases in mRNA.

Is DNA replicated in transcription?

The mechanism of transcription has parallels in that of DNA replication. Unlike DNA replication, in which both strands are copied, only one strand is transcribed. The strand that contains the gene is called the sense strand, while the complementary strand is the antisense strand.

What is the first step in transcription?

Transcription Initiation. The first step in transcription is initiation, when the RNA pol binds to the DNA upstream (5′) of the gene at a specialized sequence called a promoter (Figure 2a). In bacteria, promoters are usually composed of three sequence elements, whereas in eukaryotes, there are as many as seven elements …

What are the 5 steps of transcription?

Transcription is the name given to the process in which DNA is copied to make a complementary strand of RNA. RNA then undergoes translation to make proteins. The major steps of transcription are initiation, promoter clearance, elongation, and termination.

What are the three stages of transcription?

Stages of Transcription. The process of transcription can be broadly categorised into 3 main stages: initiation, elongation & termination.

The first step of transcription is called pre-initiation. RNA polymerase and cofactors (general transcription factors) bind to DNA and unwind it, creating an initiation bubble. This space grants RNA polymerase access to a single strand of the DNA molecule.

Which process is part of transcription?

Transcription is the process by which DNA is copied (transcribed) to mRNA, which carries the information needed for protein synthesis. Transcription takes place in two broad steps. First, pre-messenger RNA is formed, with the involvement of RNA polymerase enzymes.
