Why is it important that a signal to stop translation be part of protein synthesis?

They signal to stop protein synthesis and release the amino acid chain. Stop codons are important because they signal the end of synthesis. Sometimes, mRNA is longer than what is needed for the amino acids so without stop codons, synthesis would continue until the end of the strand of RNA, leaving you with an incorrect amino acid chain.

What is the function of a signal-recognition particle?
Guide the signal sequence to the appropriate site on the rough endoplasmic reticulum for protein synthesis.
Which mRNA condon usually signals the beginning of protein synthesis?
Methionine is always the first amino acid in a protein, therefore the codon for Met would signal the beginning of protein synthesis. This codon is AUG.
A certain protein is made up of 100 amino acids What is the smallest number of bases in the messenger RNA molecule that is needed to carry the code for the synthesis of this protein?
for mRNA, it takes 3 bases (A codon) to signal that a specific amino acid should be used. In this case you would need 100x3 = 300 bases.
When a signal molecule binds to a receptor protein the receptor protein may change the?
shape.
What binds to a signal molecule enabling the cell to respond to the signal molecule?
receptor proteins bind to signal molecules

When the Golgi complex finish where do the proteins go?
The ER and Golgi complex serves a place for protein maturation. Polypeptide chain after synthesis undergoes folding events and post translation modification such as acylation, glycoscylation. Golgi vesicles secrete the protein to extracellular space if the proteins is a secretory proteins. It all depends on the destination signal in the proteins.
How are G linked protein receptors made?
G-Linked protein receptors are proteins whose N-Terminus faces the cytosol. They are threaded to a translocon and begin with a Signal anchor sequence and alternate 7 times between a signal anchor sequence and a stop transfer anchor sequence before finally finishing synthesis in the cytosol.
How is phosphorylation important in a signal transduction cascade?
Phosphorylation will turn an inactive protein into an active one, which triggers another response in the cell.
The regulation of heterotrimeric G-proteins is similar to the regulation of which one of the following processes?
The regulation of heterotrimeric G-proteins is similar to the regulation of signal transduction. Just like in signal transduction, the activation and deactivation of heterotrimeric G-proteins involve different regulatory mechanisms such as phosphorylation, nucleotide binding, and protein-protein interactions. Both processes play crucial roles in cellular signaling and control various physiological functions.
What does a protein phosphatase actually do to end a signal transduction?
Protein phosphates turn off signal transduction pathways by removing the phosphate groups from the protein kinase, making them reusable and making the kinase inscribe stopping the signal transduction pathway.
When a signal molecule binds to a receptor protein the receptor protein may change the?
shape.

What are the best nucleotide triplets that best represent a codon?
The best nucleotide triplets that represent a codon are Adenosine, Cytosine, Guanine, and Uracil (A, C, G, and U). These nucleotides form RNA molecules, which are used during protein synthesis to encode the sequence of amino acids in a protein. Each triplet of nucleotides, or codon, corresponds to a specific amino acid or a signal to start or stop protein synthesis.
What is the role of a G-protein?
They initiate signal transduction which consists of converting extracellular hormone signal to intracellular signal that creates an action.
What do you understand by frequency translation?
Suppose that a signal is bandlimited to the frequency range extending from f1 to f2.The process of frequency translation is one in which the orignal signal is replaced with a new signal whose specteal range extends from f1' to f2' and which new signal bears in recoverable form ,the same information as was borne by orignal signal.
