hey dear sweet friend ☺️ here is your answer
Modern concept of gene (Cistron,muton, recon, viral genes). After the discovery of DNA, the gene has beendefined as cistron, recon and muton. The classical gene is the smallest unit that could undergo a mutational change. A gene further divided into smaller units of function, mutation and recombination.

hey mate here is the answer ⤵️⤵️⤵️⤵️⤵️⤵️⤵️⤵️
Cistron, Recon, And Muton
The genome contains genetic information that is transmitted from parents to offspring, from one generation to the next. The genome is the blueprint for the building and maintaining of organisms. In human beings, the genome comprises of 46 molecules of DNA known as chromosomes. Of the 46, 23 come from the father and 23 from the mother. Together, these 46 chromosomes contain about 20,500 genes that are the functional units of the chromosome. Each gene more or less, encodes information that is required for one function, which may be responsible for the physical, physiological, or biochemical characteristic of the offspring.
Recent research has provided further information on gene structure, paving the way for a more specific definition of the gene and associated regions in the chromosome. Accordingly, a gene:
- is a segment of deoxyribonucleic acids
- has a sequence that is unique in the entire genome
- encodes information required to produce one protein, rRNA or tRNA
- undergoes crossing over and mutations to become recombinant
- sometimes has information that is not in one segment, but in parts spread over a region
- may (and frequently does) influence other traits
- may only be partially responsible for one trait while other genes also exert their influence on that trait
In light of the above definition of a gene, and further research on gene structure, it became necessary to divide the gene into further divisions called cistron, recon and muton.

Cistron:
☯️☯️
It is the largest element in a gene which encodes a polypeptide during protein synthesis. The term “cistron” refers to a test called cis-trans test, which is similar to a complementation test. The term “cistron” is a unit of function.
❤️❤️
Recon:
☯️☯️
They are locations within a gene which participate in recombination. There is a minimum distance between recons within a gene, and recombination cannot occur within a recon. The term “recon” is a unit of recombination.
❤️❤️
Muton:
☯️☯️
They are elements within a gene that can undergo a mutation and lead to the production of mutant phenotype. The term “muton” is a unit of mutation. Each recon may have several mutons within them, and many mutons within a recon may stay linked because of recombination.
☯️☯️
Thus, a gene may have one more than one cistrons, a cistron may have several recons, and a recon may have several mutons.
