Name the parts of an operon and why are they for prokaryotes and not eukaryotes .
-Where is it okay to have transpooons and where it may be dangerous
-what are all the Rnas and Dnas and their function
A typical operon has these distinct parts promotor, operator, structural genes. RNA polymerase binds at promotor and operator acts as on off switch for transcription of genes. Structural genes work under promotor and operator for expression of genes responsible for carrying out the designated function of the promotor.
Transposons help in gene knock out studies once integrated it is quite stable and prevent leaky expressions. Disadvantage being the random integration of transposons it will leave the gene completely non functional.
Rnas are of three types messenger RNA codes for proteins ribosomal RNA will code for ribosomal protein subunits and transfer RNA will bring the amino acids in translation complex for adding into growing polypeptide.
DNA mostly occurs either as chromosomal or plasmid DNA. Plasmid DNA codes mostly for some resistance or stress endurance genes which makes the cell able to cope up that situation. Chromosome DNA functions as hereditary material.
