Which of the following enzymes are used to join bits of DNA . -
1 Ligase
2 Primase
3 DNA polymerase
4 Endonuclease
Explanation:
Ligases are used to join bits of DNA. - Primase:- Primase is the enzymes that synthesizes RNA primers, oligonucleotides that are complementarily bound to a nucleic acid polymer. - DNA polymerase:- DNA polymerase III holoenzymes is the primary enzymes involved in DNA replication in E. coli and belong to family C polymerases.

If \(A\) and \(C\) make \(30 \%\) and \(20 \%\) of DNA, respectively, what will be the percentage composition of \(T\) and \(G\) ?
1 \(\mathrm{T}. 20 \%, \mathrm{G}. 30 \%\)
2 \(\mathrm{T}. 30 \%, \mathrm{G}. 20 \%\)
3 \(\mathrm{T}. 30 \%, \mathrm{G}. 30 \%\)
4 \(\mathrm{T}. 20 \%, \mathrm{G}. 20 \%\)
Explanation:
Chargaff's nitrogen base pairing rule states that amount of adenine is equal to thymine and guanine is equal to cytosine. Thymine- \(30 \%\), Guanine- \(20 \%\) and cytosine also- \(20 \%\).

If Adenine makes \(30 \%\) of the DNA molecule, what will be the percentage of Thymine, Guanine and Cytosine in it ?
Here \([\mathrm{A}]=30 \%\), Therefore \(\%\) of \([\mathrm{T}]\) is also \(30 \%\). Thus \([\mathrm{G}]+[\mathrm{C}]=100-60=40 \%\), \([\mathrm{G}]=20 \%\) and \([\mathrm{C}]=20 \%\)

When the centromere is situated in the middle of two equal arms of chromosomes, the chromosome is referred as :
1 Acrocentric
2 Metacentric
3 Telocentric
4 Sub-metacentric
Explanation:
When the centromere is situated in the middle of two equal arms of chromosomes, the chromosomes is called metacentric. - When the centromere is present slightly away from the middle, it is called sub-metacentric chromosome. - When the centromere is present very close to one end of the chromosome, it is known acrocentric chromosome. - When the centromere is present at terminal position, chromosome is refers as telocentric.
