Question 1

1 mark

Which of the following is a primary application of determining the proteome of simple organisms, such as bacteria, in medical technology?

Question 2

1 mark

Why is determining the proteome of a complex eukaryotic organism like a human significantly more difficult than determining its genome?

Question 3

1 mark

In the context of sequencing projects, why is it significantly easier to determine the proteome of a prokaryotic organism compared to a complex eukaryotic organism?

Question 4

2 marks

When determining the proteome of a bacterium, scientists find it much simpler than determining that of a human.
Explain why the presence of non-coding DNA and regulatory genes in humans makes this task more complex.
