All of the following are true statements about nucleic acids except one. select the exception. dna and rna are nucleic acids atp is a nucleic acid the sugar in dna has one more oxygen than the sugar in rna nucleic acids include a 5 carbon sugar and a phosphate group which of the following statements about dna is correct? thymine is a pyrimidine guanine pairs with thymine an adenine - thymine pair are bound by three hydrogen bonds guanine has one n-containing ring adenine is a smaller molecule than thymine which chemical bonds are involved in the folding of proteins? mark all that apply. hydrogen van der waals ionic covalent which functions below represent possible functions of a protein? mark all that apply. storing hereditary information in the sequence of nucleotides catalyzing biochemical reactions serving as the subunits of structureal components of the cell such as cytoskeletal elements (e. g. microtubules, actin and intermediate fibers) organizing like amphipathic lipids to form biological membranes being the end-product of photosynthesis forming structural entities such as nucleosomes, small spheres made of histones around which dna winds forming components of the ribosome, along with ribosomal rna molecules facilitating process such as dna replication, transcription and translation (example: dna replication involves an enzyme called dna polymerase that adds nucleotides to a growing strand of deoxyribonucleic acid)

1. The sugar in DNA has one more oxygen than the sugar in RNA

2. Thymine is a pyrimidine

3. All

4. catalyzing biochemical reactions; serving as the subunits of structureal components of the cell such as cytoskeletal elements; forming structural entities such as nucleosomes, small spheres made of histones around which DNA winds; forming components of the ribosome, along with ribosomal RNA molecules; facilitating process such as DNA replication, transcription and translation

Explanation:

1. The sugar in DNA is deoxyribose sugar with one oxygen less at 2nd carbon than the sugar in RNA which is ribose sugar. Nucleic acids are made up of repeats of nucleotide which consists of three units: a phosphate, a sugar and a nitrogenous base.

2. Purines are adenine and guanine. Pyrimidines are cytosine and thymine. Adenine pairs with thymine by two hydrogen bonds whereas cytosine pairs with guanine with three hydrogen bonds. Purines have two nitrogen containing rings whereas pyrimidines have only one such ring.

3. All of these bonds are involved in the folding of protein from primary to secondary to tertiary structure. Bonds such as hydrogen bonds, ionic bonds, covalent bonds and vanderwaals forces.

4. All enzymes are protein in nature which catalyze the reactions. Micro tubules, actin and intermediate fibers are also made up of protein sub-units.   Nucleosomes contain histone proteins. Ribosomal RNA associate with proteins to form ribosomes.  DNA polymerase is an enzyme which is nothing but protein in nature.
