Which one of the following pairs of codons is correctly matched with their function or the signal for the particular amino acid?
1 AUG, ACG - Start/Methionine
2 UUA, UCA - Leucine
3 GUU, GCU - Alanine
4 UAG, UGA - Stop
Explanation:
In the genetic code, a stop codon is a sequence of 3 nulceotides in DNA or mRNA that signals a half to protein synthesis in the cell. Stop codons signal the termination of this process by binding release factors, which causes the ribosomal units to disassociate, releasing the amino acid chain. Examples are UAA, UGA and UAG.

m-RNA is synthesised on DNA template in which direction . -
1 5' \( 3^{}\)
2 3' \( 5^{}\)
3 Both
4 Any
Explanation:
\(5^{} 3^{}\) is the direction of synthesis of mRNA on DNA template. mRNA is synthesized on DNA template in \(5^{} 3^{}\) direction. Synthesis of mRNA exhibits several features that are synonymous with DNA replication. RNA synthesis requires accurate and efficient initiation elongation proceeds in the \(5^{} 3^{}\) direction and RNA synthesis requires distinct and accurate termination. Transcription exhibits several features that are distinct from replication.

Which of the following cut the DNA from specific places . -
1 Restriction endonuclease (E-Co-RI)
2 Ligase
3 Exonuclease
4 Alkaline phosphate
Explanation:
Restriction endonucleases recognize the specific sequences and cut the DNA at specific places. They are known as molecular scissors and are used in recombinant DNA technology. - Ligase enzymes are used to join the two molecule by bond formation such as DNA ligase. - Exonculease removes nucleotides from the end of the polynucleotide chain, where as alkaline phosphataes removes a phosphate group from a molecule by hydrolysis.
