Answer:
a) Individual 1
b) Overall, the higher the number of mutant alleles, the greater is the concentration of cysteine in urine relative to normal values.
c) The hypothesis may be correct. If number of mutant allele in SLC7A9 is higher than number of mutant allele in SLC3A1, then concentration of cysteine in urine is lower. This means that transportation of cysteine is affected by a greater extent if mutant allele in present in SLC7A9 genetic sequence
d) concentration of cysteine is affected by mutant allele which is a complex protien. If complex protien is low cysteine is not transported back and its concentration in urine is higher
Explanation:
a) Can be inferred easily from table. Higher the mutant allel that is negative, higher is the concentration of cysteine. Hence greater the chances of cystinuria.
b) As explained in part a
c) Observe the pattern on concentration of cycteine and number of - allele. If cysteine is not transported back then its concentration in urine will be higher.
d) The complex protien helps in transportatino of cysteine by binding to it. In the absence of the ocmplex protien, cysteine tends to behave like polar molecule and stay in water that is in excess in urine.
