Question

Which of the following is the correct order of the steps in translation?

activation, elongation, initiation, termination

initiation, activation, elongation, termination

activation, initiation, elongation, termination

elongation, activation, initiation, termination

Answer 1

The correct steps in translation are initiation, followed by elongation, and ending with termination.

Step-by-step explanation:

The correct order of the steps in translation is initiation, elongation, and termination. During initiation, the small ribosomal subunit binds to the mRNA template. Following this, tRNA brings the first amino acid methionine to the start codon AUG, assembling the initiation complex. Elongation involves sequential addition of amino acids carried by tRNAs matching the mRNA codons. Termination occurs when a stop codon is reached, signaling the release of the complete polypeptide chain and disassembly of the translation components.

Answer 2

The correct order of steps in translation is activation, Initiation, elongation and termination. 1.Activation- The correct amino acid is joined to the correct transfer RNA (tRNA). Though in strict sense this is not a step in translation, nevertheless it is required for translation to proceed. 2.Initiation- the small subunit of the ribosome binds to the 5' end of mRNA with the help of initiation factors. 3. Elongation- next tRNA in line binds to the ribosome. 4. Termination- Occurs when the A-site of the ribosome faces a stop codon
