false
true or false: transcription is the process of duplicating the DNA molecule
true
true or false: protein synthesis occurs at ribosomes
true
true or false: before it divides a cell makes a copy of all its genes
true
true or false: cytokinesis is the division of a cell's cytoplasm and organelles
true
true or false: watson and crick worked out a model of DNA
false
true or false: RNA is a double-sided chain that looks something like a twisted ladder
false
true or false: in the RNA molecule uracil always pairs with cytosine
