-3) If cells are grown in a medium containing radioactive 35S, which of these molecules will be 3) labeled? A) proteins B) amylose C) nucdeic acids D) phospholipids E) both proteins and nucleic acids 4) -4) The basic structure of a nucleotide includes A) phosphorus and sulfur B) amino acids ) base, sugat, and phosphate D) mRNA, IRNA, and tRNA ) tryptophan and leucine 5) -5) Which of the following statements best summarizes the differences between DNA and RNA A) DNA nucleotides contain a different sugar than RNA nucleotides. B) The bases in DNA form base-paired duplexes, whereas the bases in RNA do not. DNA encodes hereditary information, whereas RNA does not the b different sugar than RNA nucleotides. DNA contains the base uracil, whereas RNA contains the base th ases in DNA form duplexes, whereas the bases in RNA do not and DNA nucleotides contain a D DNA encodes hereditary information, whereas RNA does not. ymineExplanation / Answer
3. Option A is the correct answer. Proteins contain sulphur while rest all do not contain sulphur and thus only proteins will be labelled.
4. Option C is the correct answer. A nucleotide consist of a nitrogenous base (adenine, guanine, thymine, cytosine and uracil) a sugar (ribose or deoxyribose) and a phosphate.
5. Option A is the correct answer. DNA nucleotide contain deoxyribose sugar while RNA nucleotide contain ribose sugar. Deoxyribose sugar contain an extra OH group. DNA and RNA (some viruses) both act as genetic material. Both DNA and RNA form base pair duplexes.
