Does peptidyl transferase require GTP?
∑ EF-Tu and EF-Ts are required for binding aminoacyl-tRNAs to the ribosome; EF-Tu/Ts requires GTP to bind to the ribosome (F18. 21); Proofreading also occurs after binding by releasing an aminoacyl-tRNA from the A site before peptide bond formation has occured, described by k4 (F18.
What are the two steps of protein synthesis called?
Protein synthesis is the process in which cells make proteins. It occurs in two stages: transcription and translation. Transcription is the transfer of genetic instructions in DNA to mRNA in the nucleus. It includes three steps: initiation, elongation, and termination.
What’s another word for protein synthesis?
Translation is another term for protein synthesis because this is the phase during which the protein molecule is formed.
Is DNA directly involved in protein synthesis?
Protein synthesis is a two-step process that involves two main events called transcription and translation. However, DNA is not directly involved in the translation process, instead mRNA is transcribed into a sequence of amino acids.
Where is the information for protein synthesis stored?
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm. Translation, the second step in getting from a gene to a protein, takes place in the cytoplasm.
How DNA directs protein synthesis?
A gene directs the synthesis of a protein by a two-step process. First, the instructions in the gene in the DNA are copied into a messenger RNA (mRNA) molecule. The sequence of nucleotides in the gene determines the sequence of nucleotides in the mRNA. This step is called transcription.
Which type of DNA does not direct the production of proteins?
Genes consist of Exons which are DNA segments transcribed into messenger RNA (mRNA) that code for specific amino acids and Introns which are DNA sequences not expressed during protein synthesis.
