Question

Arrange the steps involved in protein synthesis in the correct order:

I. Amino acids bond together to form a polypeptide chain.
II. A specific anti-codon on Transfer RNA bonds to a specific codon on Messenger RNA.
III. Messenger RNA attaches to a ribosome.
IV. Messenger RNA is produced using DNA as a template.

A) IV, III, I, II
B) IV, II, III, I
C) III, IV, I, II
D) II, IV, III, I

Answer 1

The correct order of steps in protein synthesis is IV (mRNA production), III (mRNA attachment to ribosome), II (tRNA anticodon binding to mRNA codon), and I (amino acids forming a polypeptide chain), which is option A: IV, III, II, I.

Step-by-step explanation:

The correct order of the steps involved in protein synthesis is as follows:

1. Messenger RNA is produced using DNA as a template.
2. Messenger RNA attaches to a ribosome.
3. A specific anti-codon on Transfer RNA bonds to a specific codon on Messenger RNA.
4. Amino acids bond together to form a polypeptide chain.

Therefore, the correct sequence is IV (Messenger RNA is produced using DNA as a template), III (Messenger RNA attaches to a ribosome), II (A specific anti-codon on Transfer RNA bonds to a specific codon on Messenger RNA), and I (Amino acids bond together to form a polypeptide chain). This corresponds to option A: IV, III, II, I.
