Statement I:	The codon AUG' codes for methionine and phenylalanine.
Statement II:	AAA' and 'AAG are both codons that code for the amino acid lysine.

In light of the above statements, choose the correct answer from the options given below:

1.	Statement I is correct but Statement II is false.
2.	Statement I is incorrect but Statement II is true.
3.	Both Statement I and Statement II are true.
4.	Both Statement I and Statement II are false.

Identify the correct statement:

During translation initiation in prokaryotes, a GTP molecule is needed in: 

In Meselson and Stahl experiment, DNA extracted from the culture, one generation after the transfer from 15N to 14N medium, had a hybrid or intermediate density. With each subsequent round of replication, the percentage of hybrid or intermediate-density DNA molecules extracted from the culture:
1. will remain same
2. will get reduced by half
3. will get increased by half
4. will get doubled

As opposed to DNA replication, transcription:
I. results in an RNA complement that includes the nucleotide uracil (U) in all instances where thymine (T) would have occurred in a DNA complement.
II. creates complementary RNA in 3’ – 5’ direction
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect

A cup has ${10}^5$ bacterial cells. Each bacterial cell divides in 35 minutes. What shall be the number of bacteria after 175 min?

Consider the given two statements:

1. Both I and II are correct and II explains I.
2. Both I and II are correct but II does not explain I.
3. Only I is correct.
4. Both I and II are incorrect

Only two people have twice won the Nobel Prize in the same category. One was John Bardeen in Physics and the other in Chemistry. Identify this other person whose contributions are listed below:
(i) for his work on the structure of proteins, especially that of insulin
(ii) for contributions concerning the determination of base sequences in nucleic acids [genome sequencing]

The RNA world is a hypothetical stage in the evolutionary history of life on Earth, in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. The properties of RNA make the idea of the RNA world hypothesis conceptually plausible and include:
I. RNA is known to form efficient catalysts
II. Its similarity to DNA makes clear its ability to store information

Consider the given statements regarding replication of DNA:
I. DNA is read by DNA polymerase in the 5′ to 3′ direction, meaning the new strand is synthesized in the 3' to 5' direction.
II. The leading strand is the strand of new DNA that is synthesized in the same direction as the growing replication fork.
III. The lagging strand is the strand of new DNA whose direction of synthesis is opposite to the direction of the growing replication fork.
1. Only I and II are correct
2. Only I and III are correct
3. Only II and III are correct
4. I, II and III are correct
