DNA & Mitosis
10th Grade Biology - DNA & Mitosis Study Guide
Question | Answer |
---|---|
The part of the molecule for which DNA is named is the | sugar |
In order to fit within a cell, DNA becomes more compact by | wrapping tightly around histones |
Mitosis is the process by which: | the nucleus is divided into two nuclei |
The attachment of nucleotides to form a complementary strand of DNA during replication is accomplished by | DNA polymerase |
Who built models that demonstrated that: DNA is made of two strands that twist into a double helix. | Watson and Crick |
Molecules of DNA are composed of long chains of | nucleotides |
The amount of guanine in an organism always equals the amount of: | cytosine Base pairing rules: C with G / A with T |
The region of the chromosomes where two sister chromatids are held together is called a | centromere |
As a result of mitosis, each of the two new cells produced from the parent cell during cytokinesis are: | exact copy of all the chromosomes present in the parent cell. |
True or False, In DNA replication, the two new DNA molecule has two newly-made strands. | False |
During DNA replication, a complementary strand of DNA is made from each original DNA strand. This, if a portion of the original strand is CCTAGCT, then the new strand will be: | GGATCGA |
