All of the following are true about RNA, except: RNA is not a double-helix RNA has thymine as a base. RNA does not contain deoxyribose RNA has Uracil as a base In RNA, Cytosine and Guanine are base pairs.
The following statements best describe the RNA structure EXCEPT they are double stranded because many bases are complementary to each other they are closely associated with protein synthesis they can either form secondary or tertiary structures there are three predominant forms
Which of the following statements regarding RNA is NOT true Group of answer choices a.RNA is predominantly double stranded b.RNA nucleotides are connected by phosphodiester bonds c.RNA contains the nitrogen base uracil d.RNA contains the sugar ribose
Which of the following is not a difference between RNA and DNA? a. RNA has Uracil, DNA has Thymine b. RNA is single stranded, DNA is double stranded c. RNA has Thymine, DNA has Uracil d. RNA has ribose sugar, DNA has deoxyribose sugar
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 is NOT found in RNA? A. thymine B. adenine C. uracil D. cytosine E. guanine

Which of the following is true about heterogeneous nuclear RNA? it is more common in prokaryotes than in eukaryotes it contains introns, but no exons it contains more exons than introns it contains exons, but no introns it contains more introns than exons
Which of the following is not true with respect to RNA? a). A single-stranded chain of alternating phosphate and ribose units with the bases Adenine, Guanine, Cytosine, and Thymine bonded to the ribose. b). RNA molecules are involved in protein synthesis and sometimes in the transmission of genetic information. c). The helix geometry of RNA is of A-Form. RNA strands are continually made, broken down and reused. RNA is more resistant to damage by Ultra-violet rays. d). Ribose sugar is more reactive because of C-OH (hydroxyl) bonds. Not stable in alkaline conditions.
