How does mutation, random fertilization, and crossing over contribute to genetic variation?
yaroslaw [1]
Mutation are two types somatic and germ cell mutation...as there is mutation in germ cell it will alter the normal behavior and produce variation !

random fertilization also causes variation as different setup of genes meets with another different...so chances of variation increases !

and third crossing over is in meiosis when chiasmata forms....so in this two homologous chromosome attach to each other and on separation ... some part exchange so leads to variation !

A student observes 5,000 RFUs in a 200μl aliquot from a G3-500 ml culture. How many total RFUs will be present in a G3-15ml samp
natka813 [3]

Answer:

The maximum no. of RFUs collected in the purification procedure = 3.05 \times 10^5 RFUs

Explanation:

No. of RFUs in a 200 ul (0.2ml) aliquot = 5000 RFUs

So, No. of RFUs in G3-500 ml culture = 5000 \times \frac{500 ml}{0.2 ml} RFUs

                                                               = 5000 \times 2500 RFUs  

                                                                = 1.25 \times 10^7 RFUs

Similarly, No. of RFUs in a G3-15ml sample = 5000 \times \frac{15 ml}{0.2 ml} RFUs

                                                                          = 5000 \times 75 RFUs

                                                                          = 3.75 \times 10^5 RFUs

The maximum no. of RFUs collected in the purification procedure

= 3.75 \times 10^5 \times 80% RFUs

= 3.75 \times 10^5 \times 0.80 RFUs

= 3.05 \times 10^5 RFUs
