name the 3 dimensional shape of the DNA molecule. what is the term that means "base pairing"?

Answer 1

The 3D shape of a DNA molecule is a double helix. Base pairing is the pairing of the bases. There are 4 different bases in DNA:

adenine, guanine, thymine, cytosine

Adenine ALWAYS pairs with thymine.

Guanine ALWAYS pairs with cytosine.

Answer 2

Double Helix. Base Pairing=two nucleotides on opposite complementary DNA or RNA strands that are connected via hydrogen bonds

Answer 3

The 3D shape is known as a double helix. "Base Pairing" is what is meant when one refers to which bases (A,G,C or T - the four deoxyribonucleosomes that make up DNA) pairs up, or bonds to, its counter base on the opposite helix.

So, two helices are wrapping around each other to make the double helix. Now, what keeps them together as they wrap around each other are corresponding base pair. The "A" nucleosome on helix 1, pairs to a "T" nucleosome on helix 2 - and vice versa. Similarly, a "C" nucleosome will bind to a "G" nucleosome on the opposite strand of the double helix.

It is base-pairing that holds the two strands of the double helix in place.

Answer 4

The 3 dimensional shape is called the "Double Helix" and base pairing has to do with the pairing of chromosomes.

Answer 5

Hi. The second part: From the web "The hydrogen bonding of complementary nitrogenous bases, one purine and one pyrimidine, in DNA and in hybrid molecules joining DNA and RNA."

Answer 6

Double helix.

Base pairing is two nucleotides joined together by hydrogen bonding in DNA or RNA. This is sometimes refered to as just bp.

Answer 7

I often spend my half an hour to read this blog's posts daily along with a mug of coffee.

Answer 8

This is a really good question

Answer 9

double helix.

Answer 10

I do not consider that to be true
