    A dna acts as a template for RNA synthesization during ________. 

    Explanation
    During transcription, the DNA molecule serves as a template for the synthesis of RNA. This process involves the enzyme RNA polymerase binding to a specific region of the DNA called the promoter. The RNA polymerase then moves along the DNA strand, unwinding it and synthesizing a complementary RNA molecule. This RNA molecule is an exact copy of one of the DNA strands and carries the genetic information from the DNA to the ribosomes, where it is used as a template for protein synthesis.

    A promoter's role in protein synthesis is binding and initiating transcription. 

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A promoter is a region of DNA that initiates the transcription of a particular gene. It acts as a binding site for RNA polymerase, which then starts the process of transcription. Therefore, the statement that a promoter's role in protein synthesis is binding and initiating transcription is true.

    A gene codes for a recessive character.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A gene codes for a HEREDITARY CHARACTER.

    What's being shown in the animation above? (Click 2)

    • Translation

    • Chromosome synthesis

    • Transcription

    • DNA replication

    Correct Answer(s)
    A. Translation
    A. Transcription
    Explanation
    The animation is showing the process of both translation and transcription. Translation is the process where the information in mRNA is used to synthesize proteins, while transcription is the process where DNA is used as a template to create mRNA. Both processes are essential for protein synthesis in cells.

    Complete the base sequence of the base pairs (which is the correct sequence?).  ACAGTGC

    • CACUGUA

    • UGUCACG

    • GUGACAU

    • TGTCACG

    Correct Answer
    A. UGUCACG
    Explanation
    The correct answer is UGUCACG because it complements the given base sequence ACAGTGC. In DNA, the base pairs are always paired in a specific way: A with T and C with G. Therefore, the complementary sequence for ACAGTGC would be TGTCACG.

    The human genome is of such a grand size that it would take ____ years for a person to read all of the sequences out loud.

    • 2

    • 5

    • 60

    • 10

    Correct Answer
    A. 10
    Explanation
    The human genome is composed of approximately 3 billion base pairs. If a person were to read all of these sequences out loud, it would take a considerable amount of time. Assuming an average reading speed of 200 words per minute, it would take about 15 years to read a sequence of 3 billion base pairs. Therefore, it would take more than 10 years for a person to read all of the sequences out loud.

    • three complementary nucleotides

      DNA, RNA, And Protein Synthesis - Quiz
    Correct Answer(s)
    A. the anticodon
    A. three complementary nucleotides
    Explanation
    The other end of each tRNA contains the anticodon, which is a sequence of three nucleotides that is complementary to a specific codon on the mRNA. This allows the tRNA to recognize and bind to the correct codon during protein synthesis. Therefore, the correct answer is the anticodon and three complementary nucleotides.
