Gene Control chart

Question 1

Dna Chromatin prokaryotic

Answer 1

circular Dna, no histones, no functional groups, no heterochromatin, no nucleus, no transcripting processing control, no introns. Less DNA, less options

Question 2

eukaryotic DNA chromatin

Answer 2

chromatin structure regulation, inactivates 75 percent into chromatid. Heterochromatin- tightly compacted, lineazr DNA, have histones which have acetyl group to make easier to copy, DNA gets methylated to slow down

Question 3

Coordinate functionally related genes for prokayotic

Answer 3

Operons- use genes functionally relateed that use same promotor, one promotor with several genes

Question 4

Coordinate functionally related genes for eukaryotic

Answer 4

no operons, RNA polymerase with GTF binds to proximal C. e. . RNA poly binds to promotor, GTF binds to control elements.

Question 5

Positive control Prokaryotic

Answer 5

speeds up production, enhancers bind to promotor, allosteric

activators bind to promotor

Question 6

positive control eukaryotic

Answer 6

activator STF- speeds up- binds to CE distal, enhancer

Question 7

default for prokaryotic

Answer 7

on

Question 8

default for eukaryotic

Answer 8

off

Question 9

negative control prokaryotic

Answer 9

slows or stops function, feedback inhibition allosteric enzymes, repressors blocking transcription,
repressors made by regulatory genes

Question 10

negative control, when repressors made an active form

Answer 10

gene off, so inducible, Lac, Catabolic

Question 11

negative control, when repressors made an in active form

Answer 11

usually on, repressible, trp available, anabolic

Question 12

negative control eukaryotic

Answer 12

STF- repressor

goes with DCE, slows process down to regular, have to remove ALL transcription factors to stop
