WebCistron is a part of the DNA coding for a polypeptide. In case of eukaryotes, the structural gene in the transcription unit is monocistronic consisting of one cistron each while in prokaryotes as in bacteria the structural gene is polycistronic. Web(a) Cistron : It is the unit of function. Cistron represents a segment of the DNA molecule and consists of a linear sequence of nucleotides, which controls some cellular function. In E. Coli cistron may contain about 1500 base pairs. Some cistrons may contain as many as 30,000 base pairs.
WebCistron is the functional unit of the DNA that encodes for the translation. The codons on the DNA in the region of cistron helps in the synthesis of proteins by the process of translation. The mRNA which encodes for the single polypeptide is known as monocistronic while those who synthesize for the number of polypeptides is known as polycistronic. WebSolution: The term cistron is used to describe the locus responsible for generating a protein. It can also be defined as the segment of DNA that contains all information for production of single polypeptide. Questions from Manipal 2012 1. Striped muscles are 2.

WebTogether they form a functional unit (an equivalent of the prokaryotic cistron). Intron: This is the non-coding RNA part of the mRNA that is removed from the mRNA through splicing to form an exon for protein synthesis. Poly-A tail: This is a homo-oligonucleotide part that occurs on the 3’-OH-terminal of eukaryotic mRNAs. WebIn terms of complementation, the word cistron can be used in place of gene. The gene as a functional unit is a sequence of nucleotides in the DNA molecule that codes for one …
WebA cistron is defined as the unit of function that exhibits cis-trans test; it is not the unit of inheritance. A gene carries several cistrons. Chromosomes are the threadlike structures, present in the nucleus, and are made up of DNA and proteins.
