Which of the following $rRNA$ acts as a ribozyme in prokaryotic cells?

The first phase of translation is:

Which of the following statements is $INCORRECT$ for the elongation of the polypeptide chain during protein synthesis?

For every single amino acid incorporated in a peptide chain,$1$ $ATP$ and $2$ $GTP$ molecules are used.

Give scientific reasons: It is essential that $tRNA$ binds to both amino acids and $mRNA$ codon during protein synthesis.

Read the following statements and choose the correct set of statements:
$(a)$ $\text{tRNA}$ has an anticodon loop that has bases complementary to the code.
$(b)$ The $\text{tRNA}$,also called $\text{sRNA}$,was known before the genetic code was postulated.
$(c)$ For termination codon,there is a specific $\text{tRNA}$ that is referred to as terminator $\text{tRNA}$.
$(d)$ The secondary structure of $\text{tRNA}$ has been depicted that looks like an inverted $L$.
Choose the correct answer from the options given below:
