Question

The idea that a single gene coded for a polypeptide rather than an enzyme was evident from the
A. Use of x-ray to make nutritional mutants in bread mold
B. Transformation of bacteria from rough and non-virulent to smooth and virulent
C. Presence of a mutation in one chain of haemoglobin but not in the other
D. Discovery that mutated genes changed enzymes in a biochemical pathway

Answer 1

According to one quality one polypeptide hypothesis, the data encased in one quality is sufficient to shape one polypeptide in a very manner of speaking. Characteristics control the association, taking everything into consideration.

Step by step answer: The possibility of the standard is and has reliably been a continuously creating one. To convey a structure its arrangement of encounters is isolated into conventional, neoclassical, and current periods.
-The customary view won into the 1930s and envisioned the standard as an indistinguishable unit of genetic transmission, recombination, change, and limit. The disclosure of intragenic recombination during the 1940s and also the establishment of DNA because the physical reason of heritage incited the neoclassical thought of the standard, which won until the 1970s.
-During this view the standard (or cistron, because it was called by then) was apportioned into its constituent parts, mutons, and recons, identified as nucleotides. Each cistron was acknowledged to be answerable for the combo of a lone mRNA and thus for one polypeptide. This collinearity hypothesis won from 1955 to the 1970s.
-Ranging from the mid-1970s, DNA advancements have provoked the bleeding edge season of import conceptualization, wherein none of the old-style fonts or neoclassical guidelines are satisfactory to portray a top quality.
-Present-day disclosures fuse those of repeated characteristics, part characteristics, and elective joining, gathered characteristics, covering characteristics, transposable characteristics, complex publicists, various polyadenylation objections, polyprotein characteristics, modifying of the fundamental record, and settled characteristics.
Hence, Option C is the correct answer

Note: A pair of proteins are mixed and a few are hormones. The proteins are involved in polypeptides-long chains of amino acids. A pair of proteins contain at any rate two polypeptides associated and twisted around one another.
