The following is a sample segment of a $DNA$ strand. What does the sequence of bases on the opposite strand show? Is there anything special about it?
$5' -GAATTC -3'$
$3' -CTTAAG -5'$

Identify the correct features of $DNA$ from the following statements:
$(i)$ It is made of two polynucleotide chains.
(ii) The backbone is constituted by sugar and phosphate.
(iii) The two chains have anti-parallel polarity.
(iv) The bases in the two strands are linked through $H$-bonds.
$(v)$ Both chains are coiled in a right-handed fashion.

Select the incorrect match with respect to genetic material.

Histones are enriched with $-$

The two strands of $DNA$ are

$A$ given double-stranded $DNA$ molecule is $1,00,000$ base pairs long. The length of this $DNA$ molecule will be:
