there are multiple answers correct
MS Which of the following events occur during prokaryotic translation termination? The small ribosomal subunit binds with a specific tRNA to the mRNA and scans for a start codon. A tRNA recognizes the stop codon and the ribosome dissociates from the mRNA A protein recognizes the stop codon and the ribosome dissociates from the mRNA. A tRNA binds a codon and the ribosome adds amino acids from each tRNA to the polypeptide chain. Codons in...

Please explain
Why is a cap added to MRNA, but not to 1RNA or RRNA? Each of the three types of RNA are transcribed by different RNA polymerases. Only RNA polymerase II, involved in mRNA synthesis, contains a domain capable of interacting with enzymes that form the cap. Transcription and processing of MRNA occur in the nucleus, where cap binding proteins are found. These proteins, which add and modify the cap, are not found in the cytoplasm, where tRNA and...

15. Translation (RNA protein) has three main stages: initiation, elongation, and termination. a. Initiation occurs when the small ___________________ subunit binds to the ____ end of mRNA and is then joined by the large _________________ subunit (which has three sites called the A, P, and E sites). Once the complex is formed, the _______________ begins to read the mRNA in a ____ to ____ direction. When it reaches the first start codon (_________) a tRNA carrying the amino acid ______________________...

The genetic code is read in groups of three (3) nucleotides called codons. Some mutations are silent because they have no effect on the phenotype. How is that possible? Since there was a mutation in one of the codons, that gene will not be expressed. o It is not possible, mutations are always expressed and always have an effect The mutation changed the codon but the new codon codes for the same amino acid The ribosome knows there was a...
