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 types of amino acids are available from which to make proteins? Your Answer:20 20 Howmany amino acids are classified as being essential amino acids? Your Answer:9 9 Where can the two major types of nucleic acids be found in the cell, and what are theirroles? 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 the inheritied information and using it to synthesize protein. DNA is foundin the nucleus, mitochondria, and chloroplast. RNA is found in the nucleus, cytoplasm,and ribosomes. While both DNA and RNA can be found in the nucleus (center of the cell), 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.
