What is Watson and Crick's DNA model?
DNA is a double helix made of two strands linked together with hydrogen bonds.
How many strands of nucleotides make up DNA double helix?
In dna there are 4 strands which join each part of the dna together, these are t and a , and g and c each one of these contains 200-3000 atoms depending on wether it dna or mrna
How many nucleotides are in 1 nanogram of DNA?
2, one on each side of the double helix
How many bases are found in one turn of the DNA double helix model?
In molecular biology, the term double helix[1] refers to the structure formed by double-stranded molecules of nucleic acids such as DNA and RNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure. The term entered popular culture with the publication in 1968 of The Double Helix: A Personal Account of the Discovery of the Structure of DNA, by James Watson.The DNA double helix is a spiral polymer of nucleic acids, held together by nucleotides which base pair together.[2] In B-DNA, the most common double helical structure, the double helix is right-handed with about 10-10.5 nucleotides per turn.[3] The double helix structure of DNA contains a major groove and minor groove, the major groove being wider than the minor groove.[2] Given the difference in widths of the major groove and minor groove, many proteins which bind to DNA do so through the wider major groove.[4]
How do nitrogen bases along a gene serve as a genetic code?
Yes, it is found in pairs Adenine with Thymine and Guanine with Cytosine...they are directly across from each other (horizontally) on the DNA line ( also known as a double helix) there can be many of these on one double helix
What is Watson and Crick's DNA model?
DNA is a double helix made of two strands linked together with hydrogen bonds.
How has double helix of DNA helped the world?
The double helix of DNA has explained many functional aspects of this genetic molecule. It has enabled the task of identification by DNA fingerprinting.
How many bases does a double helix have after the complementary strand is added?
double the amount of bases (or x2)

What is a strand of DNA?
it is a ladder like structure Improvement by REAP3R11210: DNA stands for Deoxyribonucleic acid, and contains many different chemicals. (Ribose, Phosphate groups, Thymine, Guanine, Cytosine, and Adenine) Its structure is like a twisted ladder-like structure, called a double helix.
How many DNA strands do have in most cells?
DNA consists of two strands of nucleotides twisted into a double helix.
How many sugar phosphate backbones does a double helix have?
It has two, the reason being is that it has to form into the famous "twisting" pose.
Is nucleus contains a double helix supercoiled DNA?
Chromosomes are build like that.Nucleus is a large organell with many components.

Why is DNA called polynucleotide?
This means " many " nucleotides strung together in the famous double helix. Like this, though actually spiral. AATGCCTTAGC TTACGGAATCG
How many DNA molecules are in a chromosomes?
There is one double helix DNA molecule per chromosome.
