Unformatted text preview: 5´. 3) The RNAs of all genes are always synthesized 5´ 3´ off the same DNA strand of the double helix. 4) The RNAs of all genes are always synthesized 3´ 5´ off the same DNA strand of the double helix. 5) Different genes can be transcribed off either strand of the double helix, for this reason some RNA are synthesized in the 5´ 3´ direction and some are synthesized in the 3´ 5´ direction. 6. Consider the sugar molecule pictured. a) What is the name of the sugar pictured? _____deoxyribose_____________ b) Circle and label the carbon that a nitrogenous base would be bound to. c) Circle and label the carbons that phosphate groups would be bound to in a polynucleotide chain. 7. The yeast tRNA Ala has the anticodon sequence 3’ CGI 5’ (where I = inosine which by wobble rules can base pair with U, C, or A). List all codons this tRNA Ala can recognize (label 5’ and 3’ ends): 5’ GCU 3’ 5’ GCC 3’ 5’ GCA 3’...
