Transcription Quiz: Biology Trivia! - Quiz

Biology is the natural science that researches life and living organisms and their physical structure, chemical activities, molecular interactions, physiological mechanisms, development, and evolution. Biology recognizes the cell as the rudimentary unit of heredity, evolution, and the mechanism that drives the species' creation and extinction. If you choose to know more about biology, look no further than this quiz.


Questions and Answers
  • 1. 

    The bases for DNA are A, T, C, and G. What are the bases for RNA?

    • A.

      A, T, C, and G

    • B.

      A, T, C and U

    • C.

      A, U, C and G

    Correct Answer
    C. A, U, C and G
    Explanation
    RNA, or ribonucleic acid, is a molecule that is similar to DNA but has a different sugar molecule and a different base. The bases for RNA are adenine (A), uracil (U), cytosine (C), and guanine (G). Unlike DNA, which has thymine (T) as one of its bases, RNA replaces thymine with uracil. Therefore, the correct bases for RNA are A, U, C, and G.

    What is made during transcription?

    • A.

      MRNA will make a copy of the DNA

    • B.

      DNA makes a copy of itself

    • C.

      TRNA will copy the DNA

    Correct Answer
    A. MRNA will make a copy of the DNA
    Explanation
    During transcription, mRNA is made from a DNA template. This process involves the enzyme RNA polymerase binding to the DNA strand and synthesizing a complementary mRNA strand by adding nucleotides that are complementary to the DNA sequence. The resulting mRNA molecule carries the genetic information from the DNA and will be used as a template for protein synthesis during translation. Therefore, the correct answer is that mRNA will make a copy of the DNA.

    What is the goal of the transcription?

    • A.

      To make ribosomes

    • B.

      To make DNA

    • C.

      To make a copy of DNA using mRNA

    Correct Answer
    C. To make a copy of DNA using mRNA
    Explanation
    The goal of transcription is to make a copy of DNA using mRNA. Transcription is the process by which the DNA sequence is converted into an RNA sequence, specifically mRNA. This mRNA molecule can then be used as a template for protein synthesis by ribosomes. Therefore, the correct answer is to make a copy of DNA using mRNA.

    What is the purpose of having mRNA?

    • A.

      So your body can do more work

    • B.

      Because the DNA can't leave the nucleus

    • C.

      To make ATP

    Correct Answer
    B. Because the DNA can't leave the nucleus
    Explanation
    The purpose of having mRNA is because the DNA cannot leave the nucleus. DNA is the genetic material that contains instructions for making proteins, but it is located within the nucleus of the cell. In order for these instructions to be carried out and proteins to be synthesized, a copy of the DNA sequence needs to be made and transported out of the nucleus. This is where mRNA comes in. mRNA is a molecule that carries the genetic information from the DNA to the ribosomes in the cytoplasm, where protein synthesis occurs. Therefore, mRNA acts as an intermediate messenger between the DNA and the protein synthesis machinery.

    If you have a strand of DNA with the nitrogen bases of A T G      G G G    C G A, what would the mRNA strand look like?

    • A.

      T A C C C C G C T

    • B.

      U A C C C C G C U

    • C.

      U T C G G G G C T

    Correct Answer
    B. U A C C C C G C U
    Explanation
    The mRNA strand is complementary to the DNA strand. In RNA, the base thymine (T) is replaced by uracil (U). Therefore, the mRNA strand would have the same sequence as the DNA strand, except that each T in the DNA is replaced by U in the mRNA. So, the correct mRNA strand would be U A C C C C G C U.

    If you have a strand of DNA with the nitrogen bases of T A G    G C A   T C A, what would the mRNA look like?

    • A.

      A U C G C T A G T

    • B.

      A U G G C T T C A

    • C.

      A U C C G U A G U

    Correct Answer
    C. A U C C G U A G U
    Explanation
    The given DNA sequence is T A G G C A T C A. In mRNA, the base T is replaced with A, the base A is replaced with U, the base G is replaced with C, and the base C is replaced with G. Therefore, the mRNA sequence would be A U C C G U A G U.

    If you have a strand of DNA with the bases C C C   G G G   T T T   A T A, what would the mRNA look like?

    • A.

      G G G C C C A A A T A T

    • B.

      G G G G G G A A A T U T

    • C.

      G G G C C C A A A U A U

    Correct Answer
    C. G G G C C C A A A U A U
    Explanation
    The mRNA sequence is complementary to the DNA sequence and replaces thymine (T) with uracil (U). Therefore, the mRNA sequence for the given DNA sequence C C C G G G T T T A T A would be G G G C C C A A A U A U.

    Where does transcription take place?

    • A.

      Ribosomes

    • B.

      Nucleus

    • C.

      Mitochondria

    Correct Answer
    B. Nucleus
    Explanation
    Transcription is the process of synthesizing RNA from a DNA template. It takes place in the nucleus of a cell. Inside the nucleus, the DNA molecule is unwound and one of the DNA strands is used as a template to produce a complementary RNA molecule. This RNA molecule carries the genetic information from the DNA to the ribosomes, where it is used as a template for protein synthesis. The mitochondria, on the other hand, are responsible for energy production in the cell and do not play a direct role in transcription.
