Thus, in eukaryotes, while transcription occurs in the nucleus , translation occurs in the cytoplasm.
Where does transcription and translation take place?
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 do transcription and translation occur inside a living cell?
Transcription occurs in the nucleus , whereas translation occurs in the cytoplasm.
Where does translation occur in the cell?
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.
Where does transcription and translation occur quizlet?
Replication and transcription occur in the nucleus , while translation occurs in the cytoplasm.
What are the 3 main steps of transcription?
- Step 1: Initiation. Initiation is the beginning of transcription. ...
- Step 2: Elongation. Elongation is the addition of nucleotides to the mRNA strand. ...
- Step 3: Termination.

What are the 4 steps of transcription?
- Initiation. The DNA molecule unwinds and separates to form a small open complex.
- Elongation. RNA polymerase moves along the template strand, synthesising an mRNA molecule.
- Termination. In prokaryotes there are two ways in which transcription is terminated.
- Processing.
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.
What occurs during translation?
What happens during translation? During translation, a ribosome uses the sequence of codons in mRNA to assemble amino acids into a polypeptide chain . The correct amino acids are brought to the ribosome by tRNA.
What are the 3 stages of translation?
Translation of an mRNA molecule by the ribosome occurs in three stages: initiation, elongation, and termination .
What is the final product of translation?
The amino acid sequence is the final result of translation, and is known as a polypeptide. Polypeptides can then undergo folding to become functional proteins. All enzymes are proteins, but not all proteins go on to become enzymes; some serve other functions.
What is the difference transcription and translation?
Hint: Transcription is the process of copying a gene’s DNA sequence to make an RNA molecule and translation is the process in which proteins are synthesized after the process of transcription of DNA to RNA in the cell’s nucleus.
What is the process of transcription and translation together?
Together, transcription and translation are known as gene expression . During the process of transcription, the information stored in a gene’s DNA is passed to a similar molecule called RNA (ribonucleic acid) in the cell nucleus.
Where does the 2nd step of protein synthesis occur?
Translation is the second step in protein synthesis. It is shown in Figure below. Translation takes place at a ribosome in the cytoplasm . During translation, the genetic code in mRNA is read to make a protein.
Where does transcription take place in eukaryotes quizlet?
In a eukaryotic cell, transcription occurs in the nucleus , and translation occurs in the cytoplasm. Transcription and translation are spatially and temporally separated in eukaryotic cells; that is, transcription occurs in the nucleus to produce a pre-mRNA molecule.
