Question

The phenomenon in which RNA molecules in a cell are destroyed if they have a sequence complementary to an introduced double-stranded RNA is called RNA interference. RNA obstruction. RNA blocking. RNA targeting. RNA disposal. CDKs form complex with to control cell cycle. Histone acetyl transferase Histone methyltransferase Cyclins Transcription factors Ethidium bromide causes mutation by: inserts between paired bases competes with natural bases removes amino groups from bases cause strand break form thymine dimmers Base analog causes mutation by: inserts between paired bases competes with natural bases removes amino groups from bases cause strand break form thymine dimmers Ultraviolet light causes mutation by: inserts between paired bases competes with natural bases removes amino groups from bases cause strand break form thymine dimmers Frameshift mutation causes: alteration of reading frame of entire protein from the point of mutation change of

Explanation / Answer

19).Cyclins

20). forms thymine dimers

21). chemical that can substitute for a normal nucleobase in nucleic acids

competes with natural bases

22). Mutation caused by ultraviolet light is a CC to TT mutation,caused when a CC dimer is mispaired with two adenine bases during replication

form thymine dimers

23). Alteration of reding frame of entire protein from the point ofmutation.
