The triplet code - Study guides, Class notes & Summaries

Transcription - DNA to make RNA; the strand of DNA transcribes the RNA with A & U and C &G together; when DNA is transcribed (in the nucleus), the result is an RNA molecule; genetic information is transferred from DNA to RNA; DNA together then RNA polymerase comes in and separates the double helix and the RNA is made; initiation--> elongation--> termination DNA replication - copying mechanism bringing appropriate nucleotide to daughter DNA molecule; strands meeting int he middle; maki...

BAP Final Exam Test Questions With Correct Answers Graded A+ A researcher is investigating that relationship between the existing species diversity in a community and the ability of an introduced non-native species to destabilize the community. Which of the following graphs is most consistent with the claim that communities with high diversity are more resistant to change than are communities with low diversity?as species diversity increases, survival of invaders decreases because mor...

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...
