Chemical analysis shows that a nucleic acid sample contains A, U, C, and G. Is this DNA or RNA? Why?
DNA contains many hydrogen bonds. Are hydrogen bonds stronger or weaker than covalent bonds? What are the consequences of this difference in strength?
Which of the following statements is correct A Adenine and cytosine are pyrimidines Adenine and guanine are both purines. Adenine is a purine and uridine is a pyrimidine D Thymidine is a pyrimidine
In the DNA structure, a purine molecule always binds with a pyrimidine molecule. How would you expect the structure to differ if Adenine forms base pairing with Guanine and Cytosine forms base pairing with Thymidine? Instead of A-T, G-C; can it be A-G, C-T? Justify your answer within five sentences
Which of the following is true of DNA but not RNA? It can polymerize by adding monomers onto either the 5' or the 3' end. It forms intermolecular base pairs, forming stable double-stranded structures. Release of PPi from the monomer provides the energy for polymerization. It has secondary structure.
What are the consequences of having pyrimidine dimers in DNA? They prevent the transcription of the DNA into RNA. These dimers distort the DNA structure and result in errors during DNA replication. They form an extra phosphodiester bond between them. They create an apyrimidinic site
DNA has unique properties that allow it to accurately retain genetic information, even after multiple rounds of replication. One aspect of DNA that allows it to accurately store genetic information is the base pairing from Chargaff's first rule of the four nucleotide bases. If the A content of a DNA molecule is 18%, what are the percentages of the remaining bases? T = G = C = % % %
All the following statements about DNA are true, EXCEPT: O DNA is a double-helix, consisting of a sugar-phosphate backbone. O DNA is made up on nucleotides, which consist of one sugar, one phosphate, and one base. O DNA consists of 4 bases - adenine, uracil, cytosine, and guanine. The two main functions of DNA are to replicate itself and to create proteins (by providing the template for protein synthesis). O The sugar in DNA is deoxyribose.
Which of the following statements about double-stranded DNA is false? * The backbone contains alternating ribose sugar and phosphate groups. The strands are formed by nucleotides linked together via phosphodiester bonds. The helix has two grooves called the major groove and the minor groove. The bases are on the outside of the helix.
Which of the following combinations is nucleotide molecule? The nitrogenous base uracil bonded to ribose and phosphate complemented with the addition of a water molecule A nucleoside resulting from the dehydration reaction between two phosphates, glycerol, and an unsaturated fatty acid. The DNA backbone consisting of three phosphate groups, a 5-carbon nitrogenous base, and a nitrogen-containing sugar residue An ATP molecule is formed by combining adenine, ribose, and three inorganic phosphate groups
Which of the following properties applies to DNA structure? Contains A, C, G, and U base pairs Single stranded Contains the sugar deoxyribose Has an extra hydroxyl (OH) group on the 2' carbon of the sugar
