What is protein synthesis in prokaryotes?
In prokaryotes, protein synthesis, the process of making protein, occurs in the cytoplasm and is made of two steps: transcription and translation. In transcription, sections of DNA called operons are transcribed to mRNA in the cytoplasm by RNA polymerase.
Where do protein synthesis occur in prokaryotes?
the cytoplasm
For instance, protein synthesis in prokaryotes occurs in the cytoplasm. In eukaryotes, the first step (transcription) occurs in the nucleus. When the transcript (mRNA) is formed, it proceeds to the cytoplasm where ribosomes are located. Here, the mRNA is translated into an amino acid chain.
How is protein synthesis different in prokaryotic cells?
1. In eukaryotes protein synthesis occurs in the cytoplasm. In prokaryotes protein synthesis begins even before the transcription of mRNA molecule is completed.
How is protein synthesis regulated in prokaryotes?
Regulation of protein synthesis in prokaryotes occurs mainly at the transcriptional level, and involves genetic units known as operons. An operon is a set of genes that are adjacent to one another in the genome and are coordinately controlled; that is, the genes are either all turned on or all turned off.
Which of the following component is required in prokaryotic protein synthesis?
Hence, the correct answer is ‘Ribosomes’.
What are the steps of protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm. Translation occurs at the ribosome, which consists of rRNA and proteins.
What is the structure of protein synthesis?
Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell’s ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein …
What is the importance of protein synthesis?
Definition of Protein Synthesis Without them, our cells couldn’t do their jobs and we would die. Like the furniture in your house, proteins wear out over time, so our cells are continuously making new proteins through the process of protein synthesis.
What are the stages of protein synthesis?
It includes three steps: initiation, elongation, and termination. After the mRNA is processed, it carries the instructions to a ribosome in the cytoplasm.
