Question

Which one is synonym to gene?
A) Recon
B) Muton
C) Cistron
D) Genome

Answer 1

Hint: Synonyms mean one of two or more words of expression having the same or similar meaning in some or all sense. The term gene here means the basis of a physical or functional unit of heredity. They are made up of DNA.

Complete answer:
To understand, we need to find out the meaning of the respective. Gene is the segment of DNA. It is the structural and functional unit of heredity. Genes code for proteins.

Now let us analyze the given options:
A) Recon: Its term was coined by Seymour Benzer for the smallest combinable unit within citron. It’s a region of genes, where there is no crossing over taking place.
B) Muton: A segment of DNA that contains all the information necessary for the production of a single polypeptide and includes both the structural sequences and regulatory sequences. A genetic element defined by means of the cis-trans complementary test for functional, allelism broadly equivalent to the sequence of DNA that codes for one polypeptides chain, including adjacent control regions.
C) Cistron: It’s the smallest unit of chromosome in which alteration can be effective in causing mutation. In early bacterial genetics, a cistron is a structural gene. It’s a coding sequence or segment of DNA encoding a polypeptide. The structural gene in the lac operon system represents the cistron. This segment helps in the transcription of mRNA.
D) Genome: It’s the set of genetic material in an organism. It’s the total genetic content in one set of chromosomes. It was named by Hans Winkler in 1920. . Genetics include segments of DNA that are involved in the coding DNA as well as introns between the exons, it is considered a unit of heredity. Gene was formerly called a factors.

Therefore the correct answer is option ‘C’ i.e, Cistron.

Note: The human genome is made up of approximately 35000 genes, or three billion chemical base pairs. The Human Genome Project, which was an international collaborative project from 1990 to 2003. The genome of eukaryotes is contained in a single haploid set of chromosomes.
