The first step in converting genetic information into proteins is transcription Transcription Synthesis of an mrna version of the instructions stored in DNA Template strand RNA polymerase performs this synthesis by transcribing only one strand of DNA The other DNA strand is called non-template, or coding strand -Matches the sequence of the mrna - expect u are where the T's are RNA polymerase do not require a primer Phosphodietser linage is formed by RNA polymerase after case pairing occurs...

How did evidence from the study of metabolic defects contribute to the fundamental relationship between genes and proteins? - ANSWER -Garrod suggested that genes dictate phenotypes through enzymes that catalyze specific chemical reactions -Symptoms of an inherited disease reflected inability to synthesize a certain enzyme. -Linking genes to enzymes required understanding that cells synthesize and degrade molecules in a series of steps called the metabolic pathway.
