Answer:
DNA has double helical structure in which the two strands run antiparallel and are connected through complementary base pair
Explanation:
Some of the physical properties of DNA are
a) It comprises of two strands that attaches with each other in a spiral helical manner thereby giving it a double-stranded helical structure
b) The two strand join each other through complementary base pairing in which A pairs with T and C pairs with G.
c) There is a phosphate group at 5' end and a hydroxyl group at 3' end.
d) Strands are antiparallel as one of the strand run in 5′to 3′direction and the other runs in a 3′ to 5′ direction.
Double cross in genetics is when which each parent is the product of a single cross.
I would say all of the above
Is that an option?
