The two polynucleotide chains in DNA molecule are attracted to each other by what?
Between nucleotides, there is a phosphodiester bond between the phosphate group of one nucleotide and the sugar of another nucleotide. Nucleotides (such as Adenine and Thymine) are held together on two strands of DNA through hydrogen bonding. This doesn't keep nucleotides together in a strand, but helps in the structure of two corresponding strands of DNA.
How many polynucleotide chains are in each DNA molecule?
hundreds and thousands =) : im looking at my book right now because i also needed this answer.
What nucleotides can be held together by weak hydrogen bonds?
DNA contains four nucleotide bases, which are adenine, thymine, cytosine and guanine. The pairs of nucleotides that can be held together by weak hydrogen bonds are purines and pyrimidines.
Are nucleotides pieces that form the dna molecule?
DNA is composed of nucleotides. DNA is essentially a polymer made up of nucleotide monomers
What are the long chains that DNA make up?
DNA is made of two strands (chains) of DNA nucleotides that are twisted, forming a double helix, often compared to a twisted ladder. The two strands are held together by hydrogen bonds between the nitrogen bases.
Are the colvalent bonds that hold nucleotide chains of DNA together polar or non polar?
nonpolar

What scientist put nucleotide chains?
Watson, Crick, and Wilkins were the three scientists that won the Nobel Prize in 1962 for Physiology or Medicine for their model of the structure of the nucleotide chains in DNA.
What type of bond holds a nucleotide together and connects each nucleotide in a DNA strand?
The backbone of the nucleotides are composed of repeating ribose (in RNA) or deoxyribose (in DNA) and phosphates held together by phosphodiester bonds between the 5's and 3's of the ribose/deoxyribose.

Which is the subunit of DNA that links together to form strands of DNA?
a nucleotide

How are nucleic acids held together?
Through covalent and hydrogen bonds. The covalent bonds hold the pentose sugar-phosphate backbone together and are alternatively called phosphodiester bonds. The hydrogen bonds are between the nitrogen bases and hold the "rungs" of the ladder together.
What links together to form strands of dna?
a nucleotide

What catalyzes the linking together of nucleotide subunits?
DNA Polymerases
