left side of chart
Blood type and allele
A (l^a)
B (l^b)
AB (l^al^b)
O (l)

Right side of chart
Possible genotypes and alleles
AA or AO (l^al^a or l^al)
BB or BO (l^bl^b or l^bl)
AB (l^al^b)
00

1. Jessica's mother has the blood type AB and her father has the blood type O. Which blood type could Jessica have? Draw a Punnett square if needed.

pka1 of melanic acid=2.7, pka2=5.7
1)how many mM of melanic acid & tris are present?
2)which pka will you see to calculate the pH?
3)what is the overall pH of the soln?

Q2)wat are the advantages of using absorption at 597/466 rather than just at 595 for measuring proteins in coomassie blue/brilliant blue reagent?

Q3)The pkas of slutamic acid are approx. 2,4,10. wat is the pH of .1! soln of monododium glutamate?

Q4).1ml of stock soln is diluted with 2.4ml of distilled water. 50microlitres of this soln id diluted with .4ml of distilled water. the overall dilution is? ( can be givin in a ratio)

please can someone help me on this ASAP
thanks a tonn !
