In DNA, what nitrogenous base complementarily pairs with T (thymine)? Adenine Cytosine Guanine Thymine Uracil A group of students was asked to describe one difference between DNA and RNA Angela said that DNA was double stranded and RNA was single stranded Brett said that DNA contains the sugar deoxyribose and RNA contains the sugar deoxyribose Charles said that both DNA and RNA are information molecules but RNA can also catalyze some biological reactions while DNA cannot. Danielle said that DNA uses the nucleotides A C, G and T, while RNA uses A, C, G, and U Elizabeth said that because RNA is only single stranded, it can only form secondary structure but since DNA is double stranded, it can form tertiary and quaternary structure If you were asked to grade these students responses, who is right and who is wrong? __Angela __Brett __Charles __Danielle __Elizabeth Right Wrong

Solution

1. In DNA, thymine always pairs with Adenine

2. Angela 1.

Brett 2. (DNA contains the sugar deoxyribose, while RNA contains ribose)

Charles 1

Danielle 1

Elizabeth 2 (like proteins RNA structure can be described as primary, secondary (e.g., hairpins), tertiary (e.g., A-minor motif) and quaternary structure (supermolecular organisation )
