- Q1What composes a nucleic acid?Sugar, sulfate backbone, hydrogenous baseNitrogenous base, pentose sugar, phosphate groupPentose head, nitrogenous sugar, phosphate baseDNA and RNA30s
- Q2ALL BUT ONE of the following is related to RNA. Which one?Single strandRiboseThymineUracil30s
- Q3Which of the following is not related to DNA?Double strandHelixDeoxyriboseUracil30s
- Q4What is the final product of the Central Dogma of Molecular Biology?ProteinDNAEnzymeRNA30s
- Q5Which of the following should occur before the Central Dogma?TranslationDNA replicationTransportationTranscription30s
- Q6What enzyme is responsible for unzipping the double stranded DNA molecule in the DNA replication process?DNA helicaseDNA ligaseDNA polymeraseOkazaki fragments30s
- Q7Which of the following scenario depicts the initiation stage of DNA replication?RNA polymerase binds to DNA separating the DNA strandtRNA locates and binds at the start codonDNA helicase unzips the double stranded DNA moleculeDNA polymerase adds DNA nucleotides to the newly synthesized strand30s
- Q8Arrange the sequence of Transcription in its proper order. I. mRNA leaves the nucleus and enters the cytoplasm. II. The DNA information is transcribed to mRNA III. RNA polymerase reaches the terminator site signaling the end of transcription. IV. RNA polymerase binds to DNA separating the DNA strand and uses only one strand as a template.II-IV-III-IIV-II-III-IIV-I-II-IIIII-IV-I-III120s
- Q9Arrange the events of Translation in its proper order. I. Elongation of polypeptide chain. II. The protein is released to the cytoplasm and is ready for use. III. mRNA attaches to a ribosome. IV. tRNA locates and binds at the start codon. V. The ribosome encounters a stop codon. VI. The ribosome moves through the mRNA and the tRNA carries anticodon with its corresponding amino acid.IV-VI-III-I-V-IIIV-III-VI-I-V-IIIII-IV-VI-I-V-III-II-III-IV-V-VI120s
- Q10Which is the simplified version of the Central Dogma of Molecular Biology?DNA – RNA - ProteinTranscription – Translation – ProteinDNA is copied by RNA to make ProteinAll of the above30s
