Molecular Biology Quizzes & Trivia

At first the quiz is easy. As you progress, the questions gradually become more difficullt. The climax of the test presents a number of Mr. Early-style questions that are too hard for the average brain to solve. But then again, we ARE in molecular biology**, where our cranial capbilities exceed the standard norm. Conquer the test!

  • 10. 
    Now let's move on to...the Mr. Early questions! Brace yourself!Early Tabbies have two colors - chocolate, or pink. The pink allele is recessive to the chocolate allele. Suppose that a heterozygous male and homozygous recessive female are crossed. The typical ratio of offspring would be 2 chocolate : 2 pink, but astonishingly, it was discovered that the ratio was instead 1.5 chocolate: 2.5 pink. This dilemma proves that
    • A. 

      A mutation or error must have occurred in the process of crossing the parents.

    • B. 

      Recessive alleles can be common.

    • C. 

      The X-Chromosome of the male parent was inflicted with a disorder that caused a malfunction in gamete formation.

    • D. 

      The alleles for Early Tabby collors are inaccurate.

    • E. 

      Due to its unresponsive nature to external growth regulators, the mother's gamete must have skipped the process of meiosis.

  • 11. 
    From mitosis, newly-formed cells
    • A. 

      Are products of uninterrupted difertilizations.

    • B. 

      Receive a share of cytoplasmic organelles duplicate during the previous interphase.

    • C. 

      Must wait, depending on the characterization of the cell, for a protein that allows it to perform its own mitosis.

    • D. 

      Is unable to develop spindles without passing through the process of cytokinetic-cytoplasmic cleavage.

    • E. 

      Exercise crossing-over to gentically diversify the organism in which it inhabits.

  • 12. 
    Last question!Which of the following explains why some organisms hermaphroditically reproduce?
    • A. 

      A code in their genes enable them to do so. Otherwise is of no significance.

    • B. 

      Because of the benefits of switching between reproductive processes.

    • C. 

      They are able to engage in mitosis but not meiosis.
