There are two strands of DNA in a somatic cell. One is derived from each parent. They lie next to each other. Looking from left to right one strand will be 3' to 5' the other will be 5' to 3' thus the strands are antiparalell. ( 3' to 5' is read as 3 primed to 5 primed, and 5' to 3' is the reverse)

There r 2 strands in a single DNA of a human being.Shape of the DNA molecule was first studied by Rosalinde Franklin in & the structure was finally worked out by Watson & Crick in the same yr.

Every DNA has two strands fool. Human's or yours.
This was established by Watson and Crick.

The 'strands' are called chromosomes and we have 46. You count then with a microscope during cell division.

2 complementary strands. You dont need to count them, its a standard number.

each DNA molecule is composed of 2 strands, they are reverse complements of each other at the sequence level.

2 strands - it's a double helix

i think it is limitless and you need a powerful microscope to count
