Proteins are large, complex molecules thatplaymany critical roles in the body. They do most of the work incellsand are required for the structure, function, and regulationof thebody's tissues and organs. They also assist with theformation ofnew molecules by reading the genetic information storedinDNA.
Accordingly, what are proteins in genetics?
Most genes contain the information needed tomakefunctional molecules called proteins. (A few genesproduceother molecules that help the cell assembleproteins.) Thejourney from gene to protein is complexand tightlycontrolled within each cell. (Amino acids are thebuilding blocksof proteins.)
Considering this, is DNA made of proteins?
DNA tells a cell how to makeproteinsthrough the genetic code. Both DNA andproteins arelong molecules made from strings ofshorter building blocks.While DNA is made ofnucleotides, proteins aremade of amino acids, a groupof 20 different chemicals withnames like alanine, arginine, andserine.
Functionally, DNA maintainstheprotein-encoding information, whereas RNA usestheinformation to enable the cell to synthesize theparticularprotein. a.1 Differences between DNA andRNA Notes:DNA stores the genetic information, where as RNAuses theinformation to help the cell producestheprotein.
