Gene Expression - Process by which DNA directs protein synthesis; transcription and translation Transcription - Synthesis of RNA under DNA direction; Produces mRNA; use same language Translation - Synthesis of polypeptide under RNA direction; Nucleic acids and amino acids use different language, Ribosomes are site of translation Triplet code - Series of three-nucleotides (make amino acids) Template strand - Provides template for RNA transcription mRNA base triplets - Codons Direction codo...

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. Describe the experiment by...

In the 1850s and 1860s, Mendel bred pea plants and examined the way that traits were passed down across generations. His conclusions, although not accepted during his lifetime established the foundation for the field of genetics. What is the most relevant summary of these conclusions? The hereditary factors responsible for traits such as shape and flower color are inherited as discrete units. The purple flower of the F1 offspring of Mendel's parental generation crosses indicate that: both a an...
