Your Answer: Proteins,Lipids, Carbohydrates, Nucleic Acids Question 4 Not yet graded / 3 pts Question 5 Not yet graded / 4 pts Question 6 Not yet graded / 10 pts Question 7 Not yet graded / 10 pts Proteins, Lipids, Nucleic Acids, Carbohydrates How many different typesof amino acids are availablefrom which to make proteins? Your Answer:20 20 Howmany amino acids areclassified as being essential amino acids? Your Answer:9 9 Wherecan thetwo major typesof nucleic acids befound in thecell, and what aretheirroles? Your Answer: DNA (deoxyribonucleic acid) has the hereditary information and is responsible for the inheritied characteristics in all organisms. RNA (ribonucleic acid) is responsible for deciphering theinheritied information and using it tosynthesize protein. DNA isfoundin the nucleus, mitochondria, and chloroplast. RNA is found in the nucleus, cytoplasm,and ribosomes. While both DNA and RNA can befound in the nucleus(centerof thecell),only RNA iscapable of leaving the nucleus. DNA contains a vast amount of hereditary information and is responsible for the inheritable characteristics of living organisms. RNA is responsible for deciphering the hereditary information in DNA and using it to synthesize proteins.
