Characteristic(s) of most DNA is / are:
A. A pairs with T by 2 hydrogen bonds.
B. Antipolarity of complementary chains
C. 20Ao diameter
D. 10 bps / turn
(a) A, C (b) A, B, C, D (c) B, C, D (d) A, B, C
The two chains of DNA have anti-parallel polarity. It means, if one chain
has the polarity 5’ ----> 3', the other has 3’ ----> 5'. This leads to the
formation of one leading and one lagging strand. Also replication is
bidirectional due to this.
