Which of the following statements is/are TRUE about nucleic acids? 1. Nucleic acids are found in the nucleoid region of prokaryotes. II. The 5' end of a nucleotide has a free OH group on the 5' carbon atom. Neither I nor II O I only

a e HOCH O OH d b OH C For the following sugar in DNA, the base would be attached to which group? a. a b. b C. C d. d e. e

3

Which is not true of both ribonucleotides and deoxyribonucleotides?     Both have a phospoether bond.     Both have 3' OH groups.     Both contain nitrogenous bases     Both have a 5-membered sugar as part of the molecule.     Both have 2' OH groups

The RNA World theory states that RNA preceded DNA as the primary information-storing molecule, and life on early earth consisted entirely of RNA molecules. Which of the following provides the most direct support for this theory? A B с D The ribose sugar on the RNA nucleotide contains a hydroxyl group that increases its chemical stability. RNA molecules do not usually form a complementary double helix and therefore require less biomolecular resources to synthesize. RNA molecules consist of only four nucleotides, making their synthesis and replication relatively simple. The chemical versatility of RNA molecules allows them to store information as well as to fold into different functional shapes.

Which type of nucleic acid contains ribose sugars?     RNA     neither DNA nor RNA     both DNA and RNA     DNA

Name 3 differences between RNA and DNA.

Nucleic acids are (choose all that apply) polymers of amino acid chains M if in the form of DNA, are primarily found in the nucleus of eukaryotes V the way that organisms store their genetic "blueprints" the independent variable O composed of a nitrogen-containing base, a 5-carbon sugar, and a phosphate group polymers of nucleotides such as adenine, cytosine, guanine, thymine

The following are the four bases found in DNA. Which base pair can form three hydrogen bonds? * NH2 NH2 CH3. N. NH 'N. NH N, NH2 O. adenine (A) guanine (G) cytosine (C) thymine (T) A-C O A-T G-C O G-T

Adenine and thymine form hydrogen bonds between them, while cytosine and guanine form bonds. O 3.2 O21 O 22 O 33 O 23
