Which of the following mRNA can be transcripted as
1 AUG.UGA.UUU
2 UAA.UAG.UGA
3 UAG.UGA.UUU
4 UGA.UUU.UAG
Explanation:
mRNA can be transcripted as AUG, UGA, UUU. Because AUG, UGA, UUU is only the sequence which have initiation codon AUG. Rest of the sequences start with the stop codon that is UAA, UAG, and UGA therefore, these sequences can not be transcribed.

During translation initiation in prokaryotes, a GTP molecule is needed in. -
1 Formation of formyl-met-tRNA
2 Binding of \(30 \mathrm{~S}\) subunit of ribosome with mRNA
3 Association of \(30 \mathrm{~S}-\mathrm{mRNA}\) with formyl mettRNA
4 Association of \(50 \mathrm{~S}\) subunit of ribosome with initiation complex
Explanation:
. During translation intiation in prokaryotes, a GTP molecule is required along with \(30 \mathrm{~S}\) ribosome, \(\mathrm{m}\) RNA with formyl met-t-RNA GTP provides energy and ribosome provide site for translation.

During DNA replication, the strands separate by
1 DNA polymerase
2 Topoisomerase
3 unwindase/helicase
4 Gyrase
Explanation:
The initiation of DNA replication occurs in two steps. First, a so-called initiator protein unwinds a short stretch of the DNA double helix. Then, a protein known as helicase attaches to and breaks apart the hydrogen bonds between the bases on the DNA strands thereby pulling apart the two strands.

In a eukaryotic transcription and translation take place
1 Only in cytoplasm
2 In nucleus and cytoplasm
3 In cytoplasm and ribosomes
4 Only in nucleus
Explanation:
In eukaryotic transcription occurs in the nucleus and translation occurs in the cytoplasm of cell..

During DNA replication, the addition of nucleotides on the lagging strand occurs
1 Towards the replicating fork
2 At a faster rate than leading strand
3 Continuosly
4 Discontinuously
Explanation:
During replication both leading and lagging strands are synthesized in \(5^{\prime} \rightarrow 3^{\prime}\) direction. Leading strand is synthesized continuously whereas lagging strand synthesized in small pieces on DNA template. So, the addition of nucleotides on the lagging strand occurs in discontinuously during DNA replication.
