Question

A gene which have a specific behaviour in cis-trans state is called as

• A. Cistron
• B. Plasmon
• C. Muton
• D. Intron

Answer 1

The correct option is A Cistron

Cistron refers to the functional unit of gene which is further divided into recon (unit of recombination) and muton (unit of mutation). The concept of cistron is based on cis-trans position effect. This test is done to know the whether the mutations in two strains are in different genes. Thus it helps in comparing the phenotypes when the two mutations are present in cis and trans configurations.

Eukaryotic genes are splitted in nature which are made up of introns- non translatable regions of DNA and exons- translatable regions of DNA.

Plasmons are the oscillations of free electrons that are the constituents that are the consequences of the formation of dipole in the material due to electromagnetic waves.

Thus, the correct answer is option A.
