Where does the transcription of DNA into mRNA occur in eukaryotes?
the nucleus
Transcription occurs in the nucleus. During transcription, a copy of mRNA is made that is complementary to a strand of DNA. In eukaryotes, mRNA may be modified before it leaves the nucleus.
What happens when DNA is 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). The newly formed mRNA copies of the gene then serve as blueprints for protein synthesis during the process of translation.
What do eukaryotic cells do after transcription?
In eukaryotic cells, the DNA is contained inside the cell’s nucleus and there it is transcribed into RNA. The newly synthesized RNA is then transported out of the nucleus into the cytoplasm, where ribosomes translate the RNA into protein.
What is the process of RNA transcription in eukaryotes?
Eukaryotic transcription is carried out in the nucleus of the cell and proceeds in three sequential stages: initiation, elongation, and termination. Eukaryotes require transcription factors to first bind to the promoter region and then help recruit the appropriate polymerase.
Which enzyme is responsible for copying DNA into an RNA transcript?
RNA polymerase
RNA polymerase (green) synthesizes RNA by following a strand of DNA. RNA polymerase is an enzyme that is responsible for copying a DNA sequence into an RNA sequence, duyring the process of transcription.
How does transcription generate mRNA that is a copy of the coding strand?
Key points: Transcription is the first step in gene expression. 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).
Is the copied model of RNA similar to the DNA strand from which it was copied?
The RNA product is complementary to the template strand and is almost identical to the other DNA strand, called the nontemplate (or coding) strand. However, there is one important difference: in the newly made RNA, all of the T nucleotides are replaced with U nucleotides.
What is transcription explain the process of transcription in eukaryotes?
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of RNA. It 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.
What happens during transcription in eukaryotes quizlet?
During transcription, RNA polymerase seperates DNA strands and uses one of the strands as a template to assemble nucleotides into a complementary strand of RNA. DNA sequences bind in the regulatory regions of eukaryotic genes and transcription factor ps control the expression of those genes.
