Transcription requires
the DNA double helix to partially unwind such
that one strand can be used as the template for RNA synthesis. The region of unwinding is called a transcription bubble.
What is required for transcription quizlet?
Transcription requires
an RNA polymerase, a DNA template and 4 ribonucleoside triphosphates (ATP, GTP, UTP, and CTP)
. Transcription requires DNA strands to be opened to allow the RNA polymerase to enter and begin making RNA. Transcription starts near special DNA sequences called promoters. You just studied 28 terms!
What is needed for transcription and translation?
Transcription and translation take
the information in DNA and use it to produce proteins
. Transcription uses a strand of DNA as a template to build a molecule called RNA. … During translation, the RNA molecule created in the transcription process delivers information from the DNA to the protein-building machines.
What is required for transcription in eukaryotes?
Eukaryotes require transcription factors to
first bind to the promoter region
and then help recruit the appropriate polymerase. RNA Polymerase II is the polymerase responsible for transcribing mRNA.
What are the 3 main steps of transcription?
Transcription takes place in three steps:
initiation, elongation, and termination
. The steps are illustrated in Figure 2. Figure 2. Transcription occurs in the three steps—initiation, elongation, and termination—all shown here.
What are the 3 processes of central dogma?
Replication, Transcription, and Translation
are the three main processes used by all cells to maintain their genetic information and to convert the genetic information encoded in DNA into gene products, which are either RNAs or proteins, depending on the gene.
What is the main goal of transcription?
The goal of transcription is
to make a RNA copy of a gene’s DNA sequence
. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.
Which of the following is not required for transcription?
RNA primers
are not required for transcription.
What happens in transcription?
Transcription is the process by which
the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA)
. … The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
Which is an example of a catabolic interconversion?
Which is an example of a catabolic interconversion?
GTP, FADH2, and NADH
. … How is free energy that is captured in the molecules NADH and FADH2 passed on in the cell? It is used to establish a proton gradient across a membrane.

What are the 6 steps of transcription?
- Initiation. Transcription is catalysed by the enzyme RNA polymerase, which attaches to and moves along the DNA molecule until it recognises a promoter sequence. …
- Elongation. …
- Termination. …
- 5′ Capping. …
- Polyadenylation. …
- Splicing.
What are the steps of translation?
Translation of an mRNA molecule occurs in three stages:
initiation, elongation, and termination
. Initiation: The ribosome assembles around the target mRNA and the start codon 5′ AUG is recognized.
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 is the start of transcription?
Transcription begins
when RNA polymerase binds to a promoter sequence near the beginning of a gene
(directly or through helper proteins). 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 are the 4 steps of translation?
Translation happens in four stages:
activation (make ready), initiation (start), elongation (make longer) and termination (stop)
. These terms describe the growth of the amino acid chain (polypeptide). Amino acids are brought to ribosomes and assembled into proteins.
