What is DNA molecule composed of?

two strands of nucleotides linked to each other by their bases

What are the bonds of nucleotides in DNA?

- Phosphate to deoxyribose/sugar is covalent bond - Between bases (A,T,C,G) is hydrogen bond

Pentose sugar in DNA has nucleotides that are __________

Deoxyribose (Deoxygenated pentose sugar)

What type of shape is DNA?

Helical and coiled. Because of two strands, it's a double helix

Because DNA strands are antiparallel _____________

One strand ends with the phosphate group of a nucleotide One strand ends with a deoxyribose (deoxygenated pentose sugar)

How are nucleotides linked together in RNA and DNA?

RNA - Condensation Reaction DNA - Hydrogen Bonds

How are the strands of nucleotides arranged in DNA?

They are parallel but because they run in opposite directions, they are ANTI-parallel

A and T, C and G are ___________

complementary base pairs
