Fill in the following blanks with appropriate options.

(A) Information present in the DNA is transcribed in the form of codons in ____(i)______ for protein synthesis.

(B) __(ii)_______is a constituent of ribosomes.

(C) Around 80% of the total cellular RNA is ___(iii)____.

(D) ____(iv)______ carries amino acids to the ribosomes and mRNA to carry out protein synthesis.

Q. Match the types of RNAs with their corresponding functions.
$\begin{array}{cc}\text{Types of RNA}& \text{Functions}\\ \text{i. tRNA}& \text{a. Primary component of ribosomes}\\ \text{ii. mRNA}& \text{b. Carries amino acid to the ribosomes}\\ \text{iii. rRNA}& \text{c. Carries information for protein synthesis}\end{array}$

Q. Fill in the blanks in the table given below.
$\begin{array}{cc}\text{Cell organelle}& \text{Function}\\ \text{Nucleolus}& \text{(i)\_\_\_\_}\\ \text{(ii)\_\_\_\_}& \text{Synthesis and transport of proteins and fat}\\ \text{(iii)\_\_\_\_}& \text{Synthesis and secretion of enzymes and hormones}\\ \text{Ribosomes}& \text{(iv)\_\_\_\_}\\ \text{(v)\_\_\_\_}& \text{Intracellular digestion}\end{array}$

Q. The following is a list of events in synthesis of protein from a DNA template.
I. mRNA attaches to the ribosome.
II. The amino acid is attached to the growing polypeptide by a peptide bond.
III. mRNA migrates from the nucleus to the cytoplasm.
IV. An aminoacyl tRNA binds to its specific codon on mRNA.
V. mRNA is transcribed from its DNA template.
Identify the correct sequence from the following options.

Q. Name the type of RNA that carry amino acids to ribosomes during proteins synthesis.

Q. Assertion :Amber codon is a termination codon. Reason: If in an mRNA, a termination codon is present, the protein synthesis stops abruptly whether the protein synthesis is complete or not.
