What else can I help you with?
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.
What is the repeating structural unit that forms RNA and DNA?
The repeating structural unit that forms RNA and DNA is a nucleotide. Each nucleotide consists of a sugar molecule, a phosphate group, and a nitrogenous base (adenine, thymine, cytosine, or guanine). These nucleotides link together to form the long chains of RNA and DNA molecules.
How does nucleotide dehydration synthesis contribute to the formation of DNA and RNA molecules?
Nucleotide dehydration synthesis is a process where nucleotides join together to form DNA and RNA molecules. During this process, a water molecule is removed, allowing the nucleotides to bond together. This contributes to the formation of DNA and RNA by creating the long chains of nucleotides that make up these molecules.
How are the two chains of a double helix held together?
The two chains of a DNA double helix are held together by hydrogen bonds between complementary base pairs. Adenine pairs with thymine, and cytosine pairs with guanine. These hydrogen bonds form the base pairs that hold the two strands of DNA together.
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.
Nucleotide chains of DNA are held together by covalent bonds are they nonpolar or polar?
The nucleotide chains of DNA are held together by covalent bonds, specifically phosphodiester bonds. Covalent bonds are generally considered nonpolar because electrons are shared equally between atoms, resulting in no partial charges along the molecule.
Are the colvalent bonds that hold nucleotide chains of DNA together polar or non polar?
nonpolar
How are the backbones of DNA held together?
The backbones of DNA are held together by covalent bonds, specifically phosphodiester bonds. These bonds form between the phosphate group of one nucleotide and the sugar group of another nucleotide, creating a strong polymer structure that makes up the backbone of the DNA molecule.

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.
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.

Which is the subunit of DNA that links together to form strands of DNA?
a nucleotide
How is the sugar phosphate backbone held together?
The sugar-phosphate backbone in DNA is held together by covalent bonds called phosphodiester bonds. These bonds link the 5' phosphate group of one nucleotide to the 3' hydroxyl group of the next nucleotide, forming a strong sugar-phosphate backbone that gives DNA its structural stability.
How are the two chains of a double helix held together?
The two chains of a DNA double helix are held together by hydrogen bonds between complementary base pairs. Adenine pairs with thymine, and cytosine pairs with guanine. These hydrogen bonds form the base pairs that hold the two strands of DNA together.
What links together to form strands of dna?
a nucleotide
