Where does transcription and translation occur in the cell?
Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
Where does DNA transcription begin and end?
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.
Does DNA transcription occur in the nucleolus?
Explanation: The nucleolus is a special structure within the nucleus that is responsible for the transcription of rRNA genes and the formation of ribosomal subunits. Transcription of mRNA, tRNA, and miRNA occurs in other regions of the nucleus.
How is DNA transcription done?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors.
Where does DNA transcription occur?
the nucleus
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. Translation reads the genetic code in mRNA and makes a protein.
How does transcription take place in eukaryotic cells?
Eukaryotic transcription is carried out in the nucleus of the cell by one of three RNA polymerases, depending on the RNA being transcribed, and proceeds in three sequential stages: Initiation. Elongation. Termination.
Which of the following takes place during transcription?
Which of the following events occurs during transcription? A molecule of RNA is formed based on the sequence of nucleotides in DNA. During transcription, RNA nucleotides line up with their complementary DNA partners, transcribing the information in DNA into RNA.
Where does DNA replication occur in the cell?
nucleus
DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication. Each side of the double helix runs in opposite (anti-parallel) directions.
Where does transcription take place in prokaryotic cells?
the cytoplasm
Prokaryotic transcription occurs in the cytoplasm alongside translation. Prokaryotic transcription and translation can occur simultaneously. This is impossible in eukaryotes, where transcription occurs in a membrane-bound nucleus while translation occurs outside the nucleus in the cytoplasm.
Does DNA polymerase transcribe DNA?
The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. RNA polymerase synthesizes an RNA strand complementary to a template DNA strand.
What is produced during transcription?
A strand of RNA is produced during the process of transcription from a strand of DNA. The RNA nucleotides that are complementary to the nucleotides of the DNA strand get added to the RNA polymerase. RNA polymerase forms the RNA sugar-phosphate backbone for the formation of the RNA strand.
Where does transcription of a gene begin on the DNA?
To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter . Basically, the promoter tells the polymerase where to “sit down” on the DNA and begin transcribing. The promoter region comes before (and slightly overlaps with) the transcribed region whose transcription it specifies.
What is the process where DNA is turned into RNA?
Transcription is the first step of gene expression, in which a particular segment of DNA is copied into RNA (especially mRNA) by the enzyme RNA polymerase. Both DNA and RNA are nucleic acids, which use base pairs of nucleotides as a complementary language.
Where does the DNA go after the transcription process?
DNA is transcribed to make an RNA inside the nucleus . The initial RNA transcript is processed into a mature mRNA before exportation to the cytosol. The mRNA contains just one coding sequence (specifying one polypeptide).
What are the steps of DNA transcription?
Some of the major steps of DNA transcription are as follows: (i) RNA Polymerase binds to DNA (ii) Elongation of DNA takes place (iii) Termination of DNA takes place. A process that involves the transcribing of genetic information from DNA to RNA is DNA transcription. Colored image 4.9 explains DNA transcription.
