Answer to Question #190466 in Biochemistry for Paul Hackman

Question

1. What are the one letter and three lettter abbriviation for the following amino acids

a.glutamine

b.lyptophan

c.lysine

2.What are forces that stabilize the double stranded DNA?

3.Give the structural differences between RNA and DNA

Answer 1

1. The one letter and three-letter abbreviation:

a. glutamine: Q and gln

b. tryptophan: W and trp

c. lysine: K and lys

2. The structure of the DNA helix is stabilized by van der Waals forces, hydrogen bonds between complementary organic bases (a base pair), and hydrophobic interactions between the nitrogenous bases and the surrounding sheath of water.

3. The three main structural differences between RNA and DNA are as follows: RNA is single-stranded while DNA is double-stranded. RNA contains uracil while DNA contains thymine. RNA has the sugar ribose while DNA has the sugar deoxyribose.
