Where does translation occur in eukaryotes ribosomes?
Translation occurs on ribosomes in the cytoplasm or rough endoplasmic reticulum.
Does transcription and translation occur at the same time in eukaryotes?
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.
Where does transcription replication and translation occur?
Making a Protein, Part 2: Translation
|Replication||Nucleus||Duplicate a full strand of DNA|
|Transcription||Nucleus||Use a strand of DNA to build a molecule of mRNA|
|Translation||Cytoplasm||Use mRNA to build an amino acid chain|
Where do transcription and translation occur in bacteria and eukaryotes respectively?
Bacterial transcription and translation occurs in the cytoplasm. In eukaryotes, transcription occurs in the nucleus and translation in the cytoplasm.
Where does translation process start?
Translation begins when an initiator tRNA anticodon recognizes a codon on mRNA. The large ribosomal subunit joins the small subunit, and a second tRNA is recruited. As the mRNA moves relative to the ribosome, the polypeptide chain is formed.
In 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?
If translation was faster than transcription, it would cause the ribosome to “collide” with the RNA polymerase in prokaryotes where the two processes can happen concurrently. Such co-transcriptional translation has become textbook material through images such as Figure 1.
What are the 3 main steps of transcription?
Transcription occurs in the three steps—initiation, elongation, and termination—all shown here.
- 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.
Where does the start of translation occur in eukaryotes vs bacteria?
In a prokaryotic cell, transcription and translation are coupled; that is, translation begins while the mRNA is still being synthesized. In a eukaryotic cell, transcription occurs in the nucleus, and translation occurs in the cytoplasm.
Where does transcription take place in the nucleus?
Transcription takes place in the cytoplasm (prokaryote) or in the nucleus (eukaryote). The transcription is performed by an enzyme called RNA polymerase. To make mRNA, RNA polymerase : Binds to the DNA strand at a specific sequence of the gene called a promoter. Unwinds and unlinks the two strands of DNA.
Why does transcription take place?
Transcription is the process by which the DNA molecule makes an RNA molecule using enzyme RNA polymerase and other proteins. The mRNA is then used to generate proteins by a process called translation which occurs in the cytoplasm. Transcription occurs in the nucleus because DNA cannot leave the nucleus. 0.0.
What is made in transcription?
Transcription is the process of making an RNA copy of a gene sequence. Translation is the process of translating the sequence of a messenger RNA molecule to a sequence of amino acids during protein synthesis.
When does transcription occur?
Transcription occurs in three distinct phases: initiation, elongation and termination. During initiation, the RNA polymerase finds the specific part of the DNA that it going to read. This part of the sequence is known as the promoter region.
