2. The second mutation you will model is the INSERTION mutation. Look at the original DNA strand and insert a TG after the second codon. Original GENE sequence: TAC GCG TTA ACA CGC CGC GCA GCA ATA ATC Rewrite the MUTATED sequence: Transcribe into mRNA: Translate into Amino Acids: How did the mutated gene change from the original strand of DNA? How was the polypeptide chain affected?

Classify this reaction: 2al+n2-> aln.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.

Asuspension of yeast cells is being grown under anaerobic conditions such that glucose is degraded to ethanol and carbon dioxide. if one wishes to follow this process by monitoring the release of 14co2, at which positions in the glucose molecule would the 14c label need to be incorporated?
