What bond DNA forms a double helix?
The base pairs are held together by hydrogen bonds.
What holds to strands of DNA molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.
How are the strands held together in the double helix?
On a single strand of DNA the nucleotides are held together by covalent bonding between the phosphate group bonded to the 5' end of the deoxyribose, which bonds to another deoxyribose molecule attached to the next nucleotide on the strand at the 3' end of the sugar. This is what holds together a single strand. When two strands of DNA that have exactly complementary base pairing (Adenine bonds with only Thymine, and Cytosine with Guanine) the base forms a hydrogen bond to the base on the opposite strand, only if the base pairing is complementary. So, in short the double helix form is held together by hydrogen bonds between the bases present on the strand.
Which bases are complementary to one another how are they held together in the double helix of DNA?
Adenine binds to Thymine Guanine binds to Cytosine Hydrogen bonding holds the bases together.
The purpose of the hydrogen bonds in double-strand DNA?
DNA consists of two long chains of nucleotides twisted into a double helix and joined by hydrogen bonds between the complementary bases adenine and thymine or cytosine and guanine. The sequence of nucleotides determines individual hereditary characteristics.
. How are complementary strands of DNA held together?
Complementary strands of DNA are held together by hydrogen bonds connecting complementary bases.
The two strands of a DNA molecule are held together by?
The strands of the DNA double helix are held together by hydrogen bonds
How are DNA molecules bound together to form a double helix?
The DNA strands are held together by hydrogen bonds between complimentary base pairs.
What is the shape of a DNA molecule formed when two twisted DNA strands are coiled into a springlike structure and held together by hydrogen bonds between the bases?
double helix
What type of bond holds together 2 strands of DNA?
Hydrogen bonding holds together the two strands of a double stranded DNA. Hydrogen bonding exists between the nitrogen base pairs.
How are the two chains of a double helix held together?
hydrogen bonds hold it together
What bond DNA forms a double helix?
The base pairs are held together by hydrogen bonds.
Did the Watson and Crick model of DNA say two strands of the helix were held together by covalent bonds?
Not covalent, hydrogen-bonds.
What holds to strands of DNA molecule to each other?
The two strands of DNA are held together by hydrogen bonds between the nitrogen base pairs.

Which type of chemical bonding holds the two strands of DNA together in the double helix?
When two strands of DNA that have exactly complementary base pairing (Adenine bonds with only Thymine, and Cytosine with Guanine) the base forms a hydrogen bond to the base on the opposite strand, only if the base pairing is complementary. So, in short the double helix form is held together by hydrogen bonds between the bases present on the strand. This means as the two strands are split apart, a new complimentary strand is formed against each, resulting in two identical double helices where there was just one before. It is by this means that the instructions for the code of life are copied and passed on.
How is DNA put together?
DNA is put togehter by series of sequence of the nucleotides.
