Students have asked these similar questions
Which of the following statements is not true?
O RNA contains ribose and DNA contains deoxyribose
O RNA contains uracil and DNA contains thymine
RNA is single strand while DNA is double strand
RNA contains nucleosides and DNA contains nucleotides
Cle
RNA molecules are more easily broken down than DNA at a high pH. This can be attributed to the fact that:
RNA has a higher melting temperature than DNA.
RNA contains uracil that helps break down the RNA, whereas DNA contains thymine.
RNA is single stranded but DNA is double stranded.
RNA is a smaller chain than DNA, which makes RNA easier to break apart than DNA.
RNA contains an oxygen at the 2' carbon of its ribose sugar whereas DNA does not.
Which of the following are true statements about DNA and RNA? Select all that apply.
RNA contains the base uracil and the sugar ribose
RNA contains the base thymine and the sugar deoyribose
The monomer (repeating subunit) of both DNA and RNA is a nucleotide (a sugar, a
phosphate group and a nitrogenous base)
RNA has two strands, while DNA is single stranded
DNA has two strands, while RNA is single stranded

- Which of the following is a way to distinguish between DNA and RNA? The number of carbon atoms in the ribose of DNA is 5; it is only 4 in the ribose of RNA. The nitrogenous bases of RNA form hydrogen bonds with one another, but those of DNA do not. There is a -OH group on the 2' carbon of the RNA sugar but not on the 2' carbon of the DNA sugar.arrow_forwardWhich 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.arrow_forwardWhich of the following is true of an RNA molecule? the number of purines always equals the number of pyrimidines the number of thiamines may or may not equal the number of adenines the number of purines may or may not equal the number of and pyrimidines the number of cytosines always equals the number of guaninesarrow_forward
- Which of the following are TRUE for RNA compared to DNA? Please select ALL correct answer options. Select 4 correct answer(s) Question 6 options: RNA contains the bases A, G, C, and U, whereas DNA contain the bases A, G, C, and T. RNA can catalyze biological reactions, but DNA cannot. DNA but not RNA can bind proteins RNA has ribose sugar in its nucleotides, rather than the deoxyribose found in DNA. RNA is usually single stranded and can make more complex three-dimensional molecular shapes than double-stranded DNA.arrow_forwardWhich of the following is a DNA nucleotide? a phosphate group, guanine and deoxyribose a diphosphate group and uridine thymine and deoxyribose a phosphate group, adenine and ribosearrow_forwardWhich of the following is cytidine? cytosine + guanine ribose + cytosine + phosphate group ribose + cytosine cytosine + deoxyribosearrow_forward
