DNA Replication

Key Questions

  • Answer:

    #"DNA"# replication happens in mitosis...

    Explanation:

    In mitosis, the cell splits apart to form two identical, same cells. That means that it has the same #"DNA"# and number of chromosomes as the previous cell. So, mitosis's main function is literally #"DNA"# replication.

  • Answer:

    Base pair in DNA replication is a way that the chromosomes have to double check to make sure that the duplication is exact.

    Explanation:

    Base pair in DNA replication is a way that the chromosomes have to double check to make sure that the duplication is exact.

    The replication is termed semiconservative since each new cell contains one strand of original DNA and one newly synthesized strand of DNA. The original polynucleotide strand of DNA serves as a template to guide the synthesis of the new complementary polynucleotide of DNA. A template is a guide that may be used for example, by a carpenter to cut intricate designs in wood.

  • Answer:

    The process where two new DNA are formed from an old one.

    Explanation:

    • Old DNA's double strand unzips.
    • Free DNA nucleotides with extra phosphates pair up with the exposed bases.
    • Neighbouring DNA nucleotides' phosphate and sugars are joined with the help of DNA polymerase.
    • SO, two new DNA are formed each containing a strand from the old DNA.

    This video provides a brief summary of this process using the DNA Workshop activity from PBS.
