    Take a look at Figure 2, panels A-D at the foot of the figure,  and answer the following;Panel C represents;

    • A protein carrying a mutation in its KDEL endoplasmic reticulum retention signal

    • An endoplasmic reticulum protein with a KDEL sequence in the hatched segment

    • A protein with a secretion leader at the N-terminus of the black segment

    • A protein with a nuclear localisation signal in the black segment

    Correct Answer
    A. A protein with a secretion leader at the N-terminus of the black segment
    Explanation
    Panel C represents a protein with a secretion leader at the N-terminus of the black segment. This is indicated by the fact that the black segment is labeled as the N-terminus, which is the starting point of a protein sequence. The presence of a secretion leader suggests that this protein is targeted for secretion outside of the cell.

    Take a look at Figure 2 and answer the following;The long and short-form proteins are most likely;

    • Created by an internal ribosome entry process

    • Created as a result of resumed scanning following translation of a uORF

    • Created as a result of a 5'-most AUG in a poor Kozak concensus

    • Created as a result of alternative splicing

    • Created as a result of a 5'-most AUG codon in a good Kozak concensus, and a downstream AUG in a poor Kozak concensus

    Correct Answer
    A. Created as a result of a 5'-most AUG in a poor Kozak concensus
    Explanation
    The correct answer suggests that the long and short-form proteins are most likely created as a result of a 5'-most AUG in a poor Kozak consensus. This means that the proteins are produced from a start codon (AUG) that is located at the 5' end of the mRNA sequence and that the surrounding nucleotide sequence is not highly favorable for efficient translation initiation. This can result in the production of both long and short forms of the protein.
