The expression of genetic traits is the O Genome Genotype Proteome O Phenotype O Proteotype QUESTION 16 The duplication of a cells DNA is called Mitosis O Replication O Transcription O Translation O Mutation QUESTION 17 The development of virulent, toxin-producing bacterial strains due to the presence of a temperate phage can occur in Bactenal conjugation O Transformation O Generalized transduction O Specialized transduction O All of the choices are correct QUESTION 18 A screening system called the--test is used for detecting chemicals with carcinogenic potential O Koch O Ames O Mutation O Cancer O lowa QUESTION 19 This molecule is synthesized as a copy of a gene on the DNA template strand O Ribosomal RNA O Messenger RNA O Transfer RNA O Primer RNA O Ribozymes QUESTION 20 Which of the following is incorrect about transfer RNA?Explanation / Answer
Answer:
15. (d) Phenotype
Explanation:
An organism's phenotype is all of its observable characteristics which are influenced both by its genotype and by the environment.
16. (b) Replication
Explanation:
DNA replication is the production of identical DNA helices from a single double-stranded DNA molecule.
17. (d) Specialized transduction
Explanation:
Certain temperate phages can also transfer only a few restricted genes of the bacterial chromosome to the recipient bacterial cell. This transfer of bacterial genes adjacent to prophage only to the recipient chromosome is called restricted or specialized transduction
18. (b) Ames
Explanation:
Ames Test is a test for determining if a chemical is a mutagen and named for its developer, Bruce Ames. The use of the Ames test is based on the assumption that any substance that is mutagenic for the bacteria used in his test may also turn out to be a carcinogen; that is, to cause cancer.
19. (b) Messenger RNA
Explanation:
Messenger ribonucleic acids (mRNAs) transfer the information from DNA to the cell machinery that makes proteins.
