Weekly Quiz Competition

Question 1
1 / -0

Which of the following is/are the characteristic(s) of genes?

A
Replication and transmission to progeny

B
Mutability

C
Storage of hereditary information

D
All of the above

Solution

All are the characteristics of genes.
Genetic material must be replicated and passed from parent to progeny cell at each cell division. Mutations are changes in the genetic sequence. Each person has enough genetic information, which is stored within the chemical structure of the molecule DNA.
Question 2
1 / -0

Which of the following does not define the transcription unit in DNA?

A
Terminator

B
Promoter

C
Intron

D
Structural gene

Solution

Introns are non-coding sections of an RNA transcript, or the DNA encoding it, which are spliced out before the RNA molecule is translated into a protein. The sections of DNA (or RNA) that code for proteins are called exons.
Question 3
1 / -0

Which of the following RNA polymerase enzymes catalyse(s) the synthesis of all types of RNA?

A
RNA polymerase I

B
RNA polymerase II

C
RNA polymerase III

D
All of the above
Question 4
1 / -0

In a genetic code, some codons do not code for amino acids that function as stop codons. Which of the following does not belong to this group?

A
UAG

B
UAA

C
UUU

D
UGA

Solution

Yes, it is correct. UUU do not code for amino acids that function as stop codons.
Question 5
1 / -0

Which of the following codons has a dual function?

A
AUG

B
UUU

C
UGA

D
UAA

Solution

AUG has a dual function. It codes for methionine (met) and it also acts as a start (or initiator) codon to start protein synthesis.
Question 6
1 / -0

In point mutation, how many base pairs are inserted or deleted?

A
Three

B
Multiples of three

C
Two

D
One
Question 7
1 / -0

Which of the following shows the correct type of mutation that takes place on insertion of three bases?

A
Inserts multiple codons

B
Inserts one codon

C
Alters the reading frame from the point of insertion

D
Inserts multple amino acids

Solution

Yes, it is correct. Insertion of three bases inserts one codon.
Question 8
1 / -0

How many loops does tRNA of a stop codon have?

A
There is one loop; an anticodon loop.

B
There are two loops; an anticodon loop and an amino acid acceptor end.

C
There are three loops; an anticodon loop, an amino acid acceptor end and ribosomal binding loop.

D
There are no tRNAs.

Solution

Yes, it is correct. tRNAs are specific for each amino acid, but there are no tRNAs for stop codons.
Question 9
1 / -0

Which of the following sequences of the steps involved in the process of polymerisation of amino acids to form a polypeptide is correct?

(1) Activation of amino acids, Termination of polypeptide synthesis, Elongation of polypeptide synthesis, Initiation of polypeptide synthesis
(2) Initiation of polypeptide synthesis, Activation of amino acids, Elongation of polypeptide synthesis, Termination of polypeptide synthesis
(3) Termination of polypeptide synthesis, Elongation of polypeptide synthesis, Activation of amino acids, Initiation of polypeptide synthesis
(4) Activation of amino acids, Initiation of polypeptide synthesis, Elongation of polypeptide synthesis, Termination of polypeptide synthesis

A
(1)

B
(2)

C
(3)

D
(4)

1.	Splicing	a.	Addition of methyl guanosine triphosphate at 5'–end
2.	Capping	b.	Addition of adenylate residues at 3'–end
3.	Tailing	c.	Removal of non-coding introns
