in proteins, certain specific orderings of secondary structure that may have a functional role and include Î²-Î±-Î² helix-turn-helix, leucine zippers, calcium binding EF hands, zinc fingers and longer orderings that take on a structural domain such as the Î²-barrel and the immunoglobulin fold.
Deoxyribonucleic acid (/diËÉksiËraÉªbÉµ.njuËËkleÉª.É¨k ËaesÉªd/ ; ËÃ¦SÉªD) dna is a molecule that carries most of the genetic instructions used in the, development functioning and reproduction of all known living organisms and many. virusesranscription is carried out by a DNA-dependent RNA polymerase that copies the sequence of a DNA strand into RNA. To begin transcribing a gene, the RNA polymerase binds to a sequence of DNA called a promoter and separates the DNA strands.
DNA polymerase 3 is also called as holoenzyme and it is the most essential component of replisome. Difference in function. DNA polymerase 1 functions helps in DNA replication. It is used for molecular biology research. During the process of replication, an RNA primer is filled in the lagging strand of the DNA.DNA polymerase 1 removes the RNA primer and fills in the nucleotides which are necessary for the formation of the DNA in the direction- 5â to 3â.t is used for molecular biology research.
