Question 1

compare and contrast prokaryotic vs eukaryotic transcription

Answer 1

prokaryotic - in cytoplasm, RNA polymerase recognizes -10 and -35 regions in promoter, initiates transcription, RNA

Question 2

DNA complementary base pairs with

Answer 2

mRNA during transcription (in prokaryotes), pre mRNA in eukaryotes, all RNAs, self

Question 3

mRNA complementary base pairs with

Answer 3

self, DNA (transcription), snRNA (splicing in eukaryotes), rRNA (SD box - translation), tRNA (translation)

Question 4

rRNA complementary base pairs with

Answer 4

self, DNA (transcription), mRNA (SD box - transcription in prokaryotes)

Question 5

tRNA complementary base pairs with

Answer 5

self, DNA (transcription), mRNA (translation)

Question 6

snRNA complementary base pairs with

Answer 6

self, DNA (transcription), pre mRNA (splicing in eukaryotes)

Question 7

proteins complementary base pair with

Answer 7

nothing - no nucleotides

Question 8

why can transcription and translation occur simultaneously in prokaryotic cells but not in eukaryotic cells
