A fruit fly Drosophila melanogaster showing  three point test cross  st+-e+-ss+  was crossed with triplet recessive mutant st-e-ss. The F1 hybrid  was the backcross with the recessive mutant and the phenotype recorded as follows;

The distance in map unit (mu) between  st+  to  e+ and e+ to ss+ is

#Unit 8. Inheritance Biology

A series of two-point crosses were carried out among five loci (a, b, c, d and e) producing the following recombination frequencies. Using these recombination frequencies, map these five loci, showing  their linkage groups, the order of the loci in each linkage group is;

What is the correct order of the loci?

In starving cells, however, such degradation would deplete essential enzymes and regulatory proteins. Lysosomes therefore also have a selective pathway, which is activated only after a prolonged fast, that imports and degrades cytosolic proteins containing the pentapeptide  , the sequence is

Lysozyme is an enzyme that destroys bacterial cell walls. It does so by hydrolyzing the β(1→4) glycosidic linkages from N- acetylmuramic acid (NAM or MurNAc) to N- acetylglucosamine (NAG or GlcNAc) in cell wall peptidoglycans. The only functional groups in the immediate vicinity of lysozyme’s reactive center that have the required catalytic properties are the side chains of Glu 35 and Asp 52.
a- Glu perform reaction in its protonated state and Asp perform reaction in its deprotonated state. 
b- Glu perform reaction in its deprotonated state and Asp perform reaction in its protonated state. 
c- both in its protonated form
d- both in its deprotonated form
