Why do cells carry out 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.
What carries out the process of transcription?
Transcription is carried out by an enzyme called RNA polymerase and a number of accessory proteins called transcription factors. Transcription factors can bind to specific DNA sequences called enhancer and promoter sequences in order to recruit RNA polymerase to an appropriate transcription site.
What part of the cell carries out translation?
Where Translation Occurs. Within all cells, the translation machinery resides within a specialized organelle called the ribosome. In eukaryotes, mature mRNA molecules must leave the nucleus and travel to the cytoplasm, where the ribosomes are located.
Which organelle carries out transcription in any cell?
For creating proteins there is a special organelle in the cell called the ribosome. The ribosome is found in the cytoplasm of the cell.
Is DNA directly involved in transcription?
In transcription, the DNA code is transcribed (copied) into mRNA. However, DNA is not directly involved in the translation process, instead mRNA is transcribed into a sequence of amino acids.
Where does translation take place within a cell?
Translation itself can be broke down into three steps: initiation, elongation, and termination. The majority of these processes take place in the cell cytoplasm or in the endoplasmic reticulum .
Where does the process of transcription occur within the cell?
Depending on the type of cell, transcription takes place in either the nucleus or the cytoplasm. Within eukaryotes – cells that contain membrane-bound organelles – transcription occurs in the nucleus. In prokaryotes – cells that do not contain organelles – the process takes place in the cytoplasm.
Where do transcription and translation take place in the cell?
In eukaryotes, transcription and translation take place in different cellular compartments: transcription takes place in the membrane-bounded nucleus, whereas translation takes place outside the nucleus in the cytoplasm.
Where does mRNA Travele to in a cell?
Messenger RNA (mRNA) then travels to the ribosomes in the cell cytoplasm , where protein synthesis occurs (Figure 3). The base triplets of transfer RNA (tRNA) pair with those of mRNA and at the same time deposit their amino acids on the growing protein chain.
