MICROBIOLOGY LAB 9 EXAM PORTAGE
LEARNING ACTUAL TEST 2026 QUESTIONS
WITH VERIFIED ANSWERS GRADED A+
◉ Two types of nucleic acids. Answer: DNA and RNA
◉ DNA. Answer: deoxyribonucleic acid, contains vast amount of
hereditary info and is responsible for the inheritable characteristics
of living organisms, made from nucleotides
◉ RNA. Answer: ribonucleic acid, responsible for deciphering the
hereditary information in DNA and using it to synthesize proteins
◉ Can DNA and RNA be found in the nucleus?. Answer: Yes
◉ Can DNA and RNA leave the nucleus?. Answer: Only RNA. DNA is
highly compact in the nucleus
◉ Three parts of a nucleotide. Answer: Nitrogenous base, sugar
called deoxyribose, and a phosphate group
◉ Four kinds of nitrogenous bases. Answer: Adenine or guanine
(purine bases) and cytosine or thymine (pyrimidine bases)
, ◉ What forms the backbone of a DNA strand?. Answer: Sugar and
phosphate
◉ What base protrudes outward from the deoxyribose sugar?.
Answer: Nitrogenous base
◉ Strands from DNA produce a. Answer: double helix (two strands
held together by hydrogen bonding)
◉ Adenine and Thymine. Answer: Complimentary bases, form two
hydrogen bonds
◉ Guanine and Cytosine. Answer: Complimentary bases, form three
hydrogen bonds
◉ RNA contains the _____ ribose rather than deoxyribose. Answer:
Sugar
◉ RNA is always ______ stranded. Answer: Single
◉ RNA contains bases. Answer: adenine, guanine, cytosine, uracil
(no thymine); U pairs with A, A can still pair with T
