The COP1-SPA complex acts as a positive regulator as well as acts as negative regulator  by shown in statements;

a) Act as negative regulator−that targets transcription factors for degradation during phytochrome and cryptochrome responses

b) Acts as a positive regulator−that targets transcription factors for degradation during phytochrome and cryptochrome responses

c) Acts as a negative regulator− during UV-B signaling by interacting with the C-terminal region of UVR8 in the nucleus UVR8- COP1-SPA complex then activates the major transcription factor HY5, which controls the expression of many of the genes induced by UV-B

d) Acts as a positive regulator during UV-B signaling by interacting with the C-terminal region of UVR8 in the nucleus UVR8- COP1-SPA complex then activates the major transcription factor HY5, which controls the expression of many of the genes induced by UV-B

Whichof the following combination from avbove statements of UVR8 is true?

#Unit 8. Inheritance Biology

You have isolated two temperature-sensitive mutations in phage l that you suspect may be in the same gene. These phage mutants are called ts-1 and ts-2. Each mutant will form plaques at 35˚C but not at 42˚C. You cross ts-1 to ts-2 phage by coinfecting E. coli at the permissive temperature of 35˚C. When the resulting phage lysate is plated at 35˚C you count 10,000 plaques per ml of phage lysate, but when the same phage lysate is plated at 42˚C, there are only 80 plaques per ml.  
If the total size of the phage is 5 x 104 bp and the total genetic map length of the phage is 100 m.u., about how far apart are the mutations in base pairs?
