See Answer →Distinguish between prokaryotic translations and eukaryotic translation.
See Answer →Briefly discuss the basic features of the genetic code.
See Answer →Aluminium has the highest nuclear charge, so its 2p peak should have the largest binding energy, but shielding effects reverse this trend.
Justify your answer.
RNA splicing

See Answer →Compare the prokaryotic DNA replication and eukaryotic DNA replication.
See Answer →The spectrum shows more aluminium atoms than nitrogen or fluorine, so its peak appears at the lowest binding energy due to dilution.
See Answer →Explain the role of DNA double helix in DNA protein complex.
See Answer →Nitrogen has more valence electrons than fluorine or aluminium, therefore its peak appears at the highest binding energy.
See Answer →Peak X corresponds to F 1s electrons, which have the highest binding energy because fluorine’s high electronegativity and small size give its 1s electrons a large effective nuclear attraction. Peak Y is N 1s and Peak Z is Al 2p.

See Answer →C- value paradox
See Answer →A photoelectron spectrum of a compound containing nitrogen (N), aluminium (Al), and fluorine (F) shows three strong peaks at the following binding energies:
Peak X: ~686 eV
Peak Y: ~399 eV
Peak Z: ~73 eV
Find the best option from the choices given below that best explains the relative positioning of these peaks in terms of binding energy.
