Question 8 (1 point) Which statement is incorrect regarding Translation? a. There are three stages in translation: Initiation, Elongation and Termination b. The first amino acid that is carried by a tRNA to the P-site is formyl- methionine (f-met). Oc. The growing peptide will be synthesized until it reaches a termination factor. d. The order in which the amino acids are added during translation is important for the function of the mature protein. Oe. A truncated protein can made during translation as a result of a frameshift mutation in the DNA.

Answer 1

provided I swer The most appropriate answer to the provide questön iso option C. BE SURE Reason in The optione is the most appropri nes for the given question because i is the only statement that is incorrect en to the demand of the question. growing peptide Syntha to take place when aches a stop termination e the stop codons that recogethe branslation The statement is en correct he termination of the growing up Synthesis will only! the ribosome reaches a stop codon in the mRNA. There are special prolecns called Red factors that recognize the ston and then disrupt the bran machinery.. 1. Bacteria has a na has 3 types of release ppes factors ix RF1 recognize stop codon - UAA & i RF2 - recognize " - UAAL - VAG UGA main factor and recognize no RF3 - Stunulate dissociation of RF1 and RF2 from the ribosome. In Eukaryote 2 ruote. 2 release factors are present a CRFI and eRF2. e RFQ is the main factor anda all 3 stop codons. So, accordingly, b the option is fall because translation is stopped when stop stop codon codon is reached not any fermination factor orer. Termination factor is recruited after recognition of stop codon Except option all other

In question 8 option a is correct as translation consists of the 3 stages mentioned,hence it cannot be the answer.

Option b is correct as the first amino acid added in prokaryote is Formyl methionine,so it cannot be the answer.

Option d is also correct because without correct sequence the protein formed would not fold into its actual form and will be biologically inactive.Hence this option cannot be the answer.

option e is also correct as a frameshift mutation may cause premature termination of translation forming a truncated protein.Hence this option also cannot be the answer.

The correct reason for all the answers are provided in the pictures above.
