The eukaryotic nucleus therefore provides a distinct compartment within the cell, allowing transcription and splicing to proceed prior to the beginning of translation. Thus, in eukaryotes, while transcription occurs in the nucleus, translation occurs in the cytoplasm.
Where does replication transcription and translation occur in prokaryotes?
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 replication transcription or translation occur in the nucleus?
In eukaryotic cells, replication and transcription take place within the nucleus while translation takes place in the cytoplasm. In prokaryotic cells, replication, transcription, and translation occur in the cytoplasm.
In what direction does DNA replication transcription and translation occur?
DNA biosynthesis proceeds in the 5′- to 3′-direction. This makes it impossible for DNA polymerases to synthesize both strands simultaneously. A portion of the double helix must first unwind, and this is mediated by helicase enzymes.
What two places in the cell can translation occur?
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. In prokaryotes, the two processes are closely coupled (Figure 28.15).
Is transcription or translation faster?
Interestingly, since every 3 base pairs code for one amino acid, the rates of the two processes are nearly matched and as noted above, this is probably not accidental. Translation that is faster than transcription would cause the ribosome to “collide” with the RNA polymerase.
Does DNA replication occur before protein synthesis?
DNA replication occurs in the S-phase in interphase when the cell gets signal to start preparing for division. DNA transcription and DNA translation are part of protein synthesis. DNA transcription occurs by copying a length of DNA template (gene coding for a polypeptide) to form mRNA (messenger RNA).
How is replication related to transcription and translation?
Replication/Transcription/Translation. Replication is the process in which a cell makes an exact copy of its own DNA (copy DNA -> DNA).
Where does DNA transcription occur in the cell?
DNA transcription occurs by copying a length of DNA template (gene coding for a polypeptide) to form mRNA (messenger RNA). DNA translation occurs when mRNA sequence is converted into complementary amino acid sequence with help of tRNA (transfer RNA) molecules and enzymes like peptidyl transferase at the ribosomes.

Where does replication take place in the cell?
Replication/Transcription/Translation Replication is the process in which a cell makes an exact copy of its own DNA (copy DNA -> DNA). Replication occurs in the S-fase in preparation to cell division during which the genetic information for the synthesis of proteins is transfered from the mothercell to the daughtercell.
Where does translation take place in the cell?
The translation follows the transcription up: in the cytoplasm, more precisely in ribosomes located in polyribosomalcomplexes or in the rough endoplasmatic reticulum, a rRNA unit binds a single-strand mRNA chain, which enhosts the genetic code as mirror of the DNA template.
