DNA Structure
This is the commonly used term to describe the shape of a strand of DNA.
What is a Double Helix?
DNA is able to to reliably replicate because of this process.
What is complementary base pairing?
Cells spend most of their life in this phase of the cell cycle.
What is Interphase?
Mitosis has four phases.
What is True?
The chromatin condenses into sister chromatids, the nuclear membrane starts to dissolve, and the spindle fibers begin to form from the centrioles.
What is the process of Prophase?
This female scientist took an x-ray of DNA.
Who is Franklin?
This enzyme "unzips" DNA.
What is Helicase?
This process results in two genetically identical daughter cells.
What is Mitosis?
This is the phase when sister chromatids attach to spindle fibers and line up in the middle of the cell.
What is Metaphase?
This is the region of DNA where replication begins.
What is the primer?
These two scientists determined the three dimensional structure of DNA.
This enzyme adds nucleotides to the growing DNA strand.
This process results in four genetically unique daughter cells.
What is Meiosis?
Cytokinesis translates to this.
What is "splitting in half of the cytoplasm?"
The tension between the centrioles and centromeres causes the cell to elongate during this phase of Mitosis.
What is Anaphase?
DNA contains these three components.
What are a phosphate group, deoxyribose sugar, and nitrogenous bases?
This is the term that describes how new DNA strands contain half of the original strand after replication.
What is Semi-Conservative?
Before transitioning into Mitosis, a cell must do these two things.
What are grow and replicate its DNA?
These organelles act like cellular pulleys.
What are the centrioles?
This is how nitrogenous bases pair.
What is Adenine to Thymine and Cytosine to Guanine?
These are the four nitrogenous bases of DNA.
What are Adenine, Thymine, Cytosine, & Guanine?
This enzyme "glues" together any gaps in the new DNA strands at the end of replication.
What is Ligase?
What is 3? (G1, S, G2)
DNA is in the form of chromatin during this phase.
What is Telophase?
Cells that make up these can remain in Interphase for their entire life cycle.
