Q21

The RNA AU/GC ratio was roughly.... To the DNA AT/GC ratio.

  • A) Similar
  • B)
  • C)
  • D)
AI Explanation
The AU/GC ratio of RNA was found to be roughly similar to the AT/GC ratio of the corresponding DNA. This relationship supported the idea that RNA composition reflects information encoded by DNA.

Q22

RNA polymerase performs essentially the same reaction in all cells from bacteria to human,

  • A) RNA
  • B)
  • C)
  • D)
AI Explanation
RNA polymerase catalyzes the synthesis of RNA by adding ribonucleotides to a growing RNA strand. Although the specific polymerases and regulatory mechanisms differ among organisms, the basic chemical reaction is conserved.

Q23

Strands of DNA are separated at the replication fork..

  • A) dsDNA
  • B)
  • C)
  • D)
AI Explanation
At the replication fork, the two strands of double-stranded DNA (dsDNA) are separated to expose their bases. Each separated strand then serves as a template for synthesis of a complementary strand.

Q24

Types of histone protein

  • A) 5
  • B)
  • C)
  • D)
AI Explanation
There are five major types of histone proteins: H1, H2A, H2B, H3, and H4. H2A, H2B, H3, and H4 form the core of the nucleosome, while H1 is the linker histone.

Q25

Simplest amino acid residues

  • A) glycine
  • B)
  • C)
  • D)
AI Explanation
Glycine is the simplest amino acid because its side chain consists of only a hydrogen atom. Its small size gives it considerable flexibility within protein structures.

Q26

The most common cyclobutane pyrimidine dimer is

  • A) thymine-thymine
  • B)
  • C)
  • D)
AI Explanation
The most common cyclobutane pyrimidine dimer (CPD) formed by ultraviolet radiation is the thymine-thymine dimer. It forms when adjacent thymine bases become covalently linked, distorting the DNA structure.

Q27

Enzyme that converts hydrogen peroxide into water and oxygen is

  • A) catalase
  • B)
  • C)
  • D)
AI Explanation
Catalase is an antioxidant enzyme that decomposes hydrogen peroxide into water and oxygen. The reaction helps protect cells from oxidative damage caused by hydrogen peroxide.

Q28

Nucleotides join with bond___

  • A) phosphodiester bond
  • B)
  • C)
  • D)
AI Explanation
Nucleotides in DNA and RNA are connected by phosphodiester bonds. These bonds form between the 3′ hydroxyl group of one sugar and the 5′ phosphate group of the next nucleotide.

Q29

CPD photolyase is present in a variety of organisms except _

  • A) placental mammals
  • B)
  • C)
  • D)
AI Explanation
CPD photolyase is found in many organisms, including bacteria, plants, fungi, and some animals. Placental mammals, including humans, generally lack functional CPD photolyase and instead rely mainly on nucleotide excision repair.

Q30

Hydrolytic deamination of cytosine is estimated to take place about _ times a day in a mammalian cell.....

  • A) 100 to 500
  • B)
  • C)
  • D)
AI Explanation
Spontaneous hydrolytic deamination of cytosine occurs frequently in mammalian cells. It is estimated to occur approximately 100 to 500 times per cell per day, producing uracil from cytosine.

Q31

Okazaki fragments vary in length from _ nucleotides in bacteria.

  • A) 1000 to 2000
  • B)
  • C)
  • D)
AI Explanation
Okazaki fragments are short DNA segments synthesized discontinuously on the lagging strand. In bacteria such as E. coli, they typically range from about 1000 to 2000 nucleotides.

Q32

Griffith theorized that some substance of the dead bacteria might be responsible for that transformation . He called that substance as the transforming principle. _

  • A) TRUE
  • B)
  • C)
  • D)
AI Explanation
Griffith observed that nonvirulent bacteria could be transformed into virulent bacteria by material from heat-killed virulent cells. He called the unknown material responsible for this change the transforming principle.

Q33

The RNA AU/GC ratio was roughly _ to the DNA AT/GC ratio___

  • A) similar
  • B)
  • C)
  • D)
AI Explanation
The AU/GC ratio in RNA was found to be roughly similar to the AT/GC ratio in DNA. This observation provided an early clue about the relationship between RNA and DNA composition.

Q35

Cisplatin was found to block cell division in __

  • A) E. coli
  • B)
  • C)
  • D)
AI Explanation
Cisplatin was found to interfere with DNA and inhibit cell division in bacterial cells such as E. coli. It forms DNA cross-links that disrupt DNA replication and cellular proliferation.

Q36

DNA helicase separate____ DNA into__

  • A) Double stranded, Single strand
  • B)
  • C)
  • D)
AI Explanation
DNA helicase unwinds the DNA double helix by separating the two complementary strands. This produces two single-stranded DNA templates that can be copied during replication.

Q37

DNA consist of ____ helical polynucleotide strands which are wound around the same axis to form ____ double helix___

  • A) Two, right handed
  • B)
  • C)
  • D)
AI Explanation
DNA consists of two polynucleotide strands wound around the same axis. The common B-form of DNA is a right-handed double helix.
