Question

Once an operon structure is known ______ for the presence of a promoter and regulatory elements _____ in the operon do not possess such DNA elements.

(a) only the first gene is predicted, whereas other genes

(b) only the first hundred genes are predicted, whereas next few genes

(c) only first two genes are predicted, whereas next few genes

(d) only first ten genes are predicted, whereas next few genes

I have been asked this question in examination.

My question is from Prediction Algorithms in chapter Promoter and Regulatory Element Prediction of Bioinformatics

Answer 1

Correct answer is (a) only the first gene is predicted, whereas other genes

Best explanation: Only the first gene is predicted for the presence of a promoter and regulatory elements, whereas other genes in the operon do not possess such DNA elements. There are a number of methods available for prokaryotic operon prediction. The most accurate is a set of simple rules developed.
