What transcribes DNA into RNA in eukaryotes?
Once the virus infiltrates one of your cells, the polymerase enzyme synthesizes mRNA transcripts for each of the genes in its genome. It then commandeers your own ribosomes and uses them to build its own proteins.
Where does translation take place in the?
Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.
Is RNA single stranded or double stranded?
single-stranded molecule
Although RNA is a single-stranded molecule, researchers soon discovered that it can form double-stranded structures, which are important to its function.
What is transcription in prokaryotes and eukaryotes?
Both prokaryotes and eukaryotes perform fundamentally the same process of transcription, with the important difference of the membrane-bound nucleus in eukaryotes. With the genes bound in the nucleus, transcription occurs in the nucleus of the cell and the mRNA transcript must be transported to the cytoplasm.
What is transcription and transcription in prokaryotes?
Prokaryotic transcription is the process in which messenger RNA transcripts of genetic material in prokaryotes are produced, to be translated for the production of proteins. Prokaryotic transcription occurs in the cytoplasm alongside translation. Prokaryotic transcription and translation can occur simultaneously.
Where does transcription and translation occur in prokaryotes?
the cytoplasm
(a) In prokaryotes, the processes of transcription and translation occur simultaneously in the cytoplasm, allowing for a rapid cellular response to an environmental cue.
Why is transcription regulated?
Transcriptional regulation is a critical biological process that allows the cell or an organism to respond to a variety of intra- and extra-cellular signals, to define cell identity during development, to maintain it throughout its lifetime, and to coordinate cellular activity.
How does transcription take place in prokaryotic cells?
Transcription in prokaryotes (and in eukaryotes) requires the DNA double helix to partially unwind in the region of mRNA synthesis. The region of unwinding is called a transcription bubble. Transcription always proceeds from the same DNA strand for each gene, which is called the template strand.
