mRNA is read by the cellular machinery during protein synthesis through a process called translation. Ribosomes attach to the mRNA and move along it, reading the genetic code in groups of three nucleotides called codons. Each codon corresponds to a specific amino acid, which is added to the growing protein chain. This process continues until a stop codon is reached, signaling the end of protein synthesis.
What else can I help you with?
What is rRNA?
Ribosomal RNA (rRNA) is a type of RNA that forms part of the ribosome, the cellular machinery responsible for protein synthesis. It helps in the binding and positioning of ribosomal proteins and mRNA during translation. rRNA plays a crucial role in the process of protein synthesis within cells.
What is the significance of the tryptophan codon in genetic coding and how does it affect protein synthesis?
The tryptophan codon is important in genetic coding because it signals the incorporation of the amino acid tryptophan into a protein during protein synthesis. This codon acts as a specific instruction for the cell's machinery to add tryptophan to the growing protein chain. If there is a mutation in the tryptophan codon, it can lead to errors in protein synthesis, potentially affecting the structure and function of the resulting protein.
Why must RNA be made during protein synthesis?
RNA is required during protein synthesis because it serves as the intermediary between DNA, where genetic information is stored, and proteins, which perform cellular functions. Messenger RNA (mRNA) carries the genetic code from DNA to ribosomes, where proteins are synthesized. Transfer RNA (tRNA) and ribosomal RNA (rRNA) also play essential roles in facilitating protein synthesis.
What binds to the mRNA during the process of protein synthesis?
During the process of protein synthesis, ribosomes bind to the mRNA to read and translate the genetic code into a protein.
Why can't DNA carry the code?
DNA is fundamentally a molecule containing genetic information, not a vehicle for carrying out actions. Its role is to store and transmit genetic information for various cellular functions, such as protein synthesis. In order for DNA to be used to carry out a specific code, additional cellular machinery and processes are required.
Where cycloheximide inhibit protein synthesis?
Cycloheximide inhibits protein synthesis in eukaryotic cells by blocking translocation on the ribosome. It binds to the 60S subunit of the ribosome and prevents the elongation of the polypeptide chain during translation. This stops the synthesis of new proteins, leading to the disruption of cellular processes that rely on protein production.

What has the author Honoree Mary Fleming written?
Honoree Mary Fleming has written: 'Protein synthesis during cellular differentiation in Nostoc muscorum'
WHAT DOES During protein synthesis messengers RNA?
Messenger RNA molecules are fed through the ribosomes during protein synthesis.
Where does protein synthesis occurs?
Protein synthesis occurs in the cytoplasm by the ribosomes.

Does protein synthesis occur during replication?
No, protein synthesis does not occur during replication. Replication is the process of copying DNA, while protein synthesis occurs during transcription and translation, where DNA is used as a template to create proteins.
What is made during initiation of protein synthesis?
During initiation phase of protein synthesis , most important thing formed is initiation complex .
In what direction does the ribosome read mRNA during protein synthesis?
The ribosome reads mRNA in the 5' to 3' direction during protein synthesis.
