Question
Who first coined the use of the term "cells" to describe the biological compartments found in organisms? [You will need to choose from a list] The formation of a bond from a condensation reaction always generates a by-product molecule of what? [You will need to choose from a list] Lois Learn lot was reading up about nucleic acids and noticed that in books and articles that strands of nucleic acids have a denoted directionality, with one end designated 5' and the other end designated 3'. But she couldn't quite figure out what they stood for. Can you help her? a) Using the diagram below, determine which are structures on the nucleotide that the 5' and 3' stand for and b) state which reason best explains why these notations are used to discuss the directionality of a nucleic acid strand.Explanation / Answer
5. Term cell was coined by Robert Hooke for the compartments organisms are made of. Cell means empty, little room.
6. The most common byproduct of condensation reactions is water molecule ie H20
7. Nucleic acids consist of sugar phosphate chain having two ends 5' end and 3' end.
a. [No diagram visible in question] Structures on nucleotides for 5' and 3' are Carbon at position 3 and position 5 of pentose sugar.
b.Reason: 5' means that carbon-5 is free for bonding in pentose sugar at this end. Whereas, on other end of sugar phosphate chain, carbon 3 of pentose sugar is free for bonding.
