ra credit This question is optional and wor In a random long DNA sequence comprising all 4 nucleotides A T G C there are 44 256 different four nucleotide sequences and there are theoretically 46 4096 possible six nucleotide sequences Therefore theoretically assuming completely random sequence DNA any particular 4 base pair recognition site restriction enzyme will cut 1 in 256 4 base pair long sequences or once every 256 base pairs while a 6 base pair recognition site restriction enzyme will cut once every 4096 bp Assuming this to be true how many restriction fragments do you hypothesize might be obtained when digesting genomic DNA from an organism with a genome of 409 6 mbp with EcoRI no calculator needed 5 pt

Why did it turn out to be important that the researchers ran the legume nodule study for more than 10 days O Because the root nodules are initiated in the first 10 days after germination Because plants don t reproduce until they are at least ten days old Because ten days worth of data was not enough to produce statistically significant results Because it takes plants and bacteria at least two weeks to learn to work together
