Which part of a nucleotide is involved in the bonding that holds DNA double helix together? Select one: O a. The nitrogenous base of a nucleotide being repelled by the surrounding water O b. The nitrogenous base of a nucleotide hydrogen bonds with the nitrogenous base of another nucleotide on the complementary strand. O c. The nitrogenous base of a nucleotide hydrogen bonds with the nitrogenous base of another nucleotide on the same strand O d. Interactions amongst deoxyribose sugars with phosphates on the same strand O e. Interactions amongst adjacent phosphate backbones

If 22% of the nucleotides in a sample of DNA contain the base adenine (A), then 22% of the nucleotides in the same sample of DNA contain the base guanine (G). True or False True False

Question 39- ( PLEASE show your work and explain your answer so I understand going forward.) What is the sequence of bases in mRNA produced from a section of the template strand of DNA that has the following sequence of bases? — G — A— T— T — C—A —

What is the length, in nm, of a linear fragment of a double-stranded DNA composed of 855 bp and in B-form?

1. Draw the two Watson-Crick Bases Pairs and show how G- C and A-T recognize each other by hydrogen bonding. 2. Draw the full structure of two nucleotides - one from DNA and one from RNA. Point out the key difference between the two. 3. Write out an example of a condensation reaction forming a phosphate-sugar bond. 4. Write out an example of a condensation reaction between a nucleic acid base and a sugar. 5. State the "Central Dogma" of biochemistry.

Deoxyadenosine monophosphate (dAMP) and guanosine monophosphate (GMP) are nucleotides. The similarities between dAMP and GMP are that they both have? -an alpha (central) carbon.-the same R group.-a phosphate group.-a pentose (5 sided) sugar-an amino group-a nitrogenous base.
