DNA Structure
DNA is stored in this organelle (cell part).
What is the nucleus?
This is the number of DNA molecules present at the end of DNA replication.
What is two?
This is the number of stages in Interphase.
What is three?
This is the number of stages in Mitosis.
What is four?
G1, S, and G2 are the three phases of this part of the cell cycle.
What is interphase?
This is the name for the shape of DNA.
What is a double helix?
When the two strands of a DNA molecule split apart, they are breaking this type of bond.
What is a hydrogen bond?
In the S phase, the cell replicates this molecule.
What is DNA?
This is the stage of mitosis where chromosomes line up in the middle of the cell.
What is metaphase?
This form of DNA is the most organized and dense.
What are chromosomes?
This is the monomer of DNA.
What is a nucleotide?
This molecule helps "unzip" the two strands of DNA during DNA replication.
What is an enzyme? (helicase)
The cell synthesizes (makes) the enzymes necessary for DNA replication in this step of interphase.
What is G1?
Chromosomes appear during this phase of mitosis.
What is prophase?
Spindle fibers attach to chromosomes at this.
What is a centromere?
This type of bond holds together the sugar and phosphate in the backbone of DNA.
What is a covalent bond?
What is one?
In interphase, and DNA in the nucleus is organized into this structure.
What is chromatin?
During this stage of mitosis, two nuclear envelopes form.
What is telophase?
DNA is in this form during interphase.
What is chromatin?
Our genetic code contains information used to build _____________.
What are proteins?
DNA replication occurs during this phase of the cell cycle.
What is the S Phase?
These are the stages of interphase in order.
What are G1, S, and G2?
These are the four phases of mitosis in order.
What are prophase, metaphase, anaphase, and telophase?
These are the full names of the four nitrogenous bases in DNA.
What are adenine, thymine, guanine, and cytosine?
