DNA structure
A-T; C-G
What is the complementary strand based on the given strand of DNA?
ATCGTTAGGC
TAGCAATCCG
What is considered the longest phase of the cell cycle? It includes the three sub phases G1 phase, S phase, and G2 phase
Interphase
What is apoptosis?
Cell death
What is the name of the phase based on the picture given in slide 1?
metaphase
What two components of the DNA molecule make up the backbone of the DNA?
What is the name of the enzyme that is responsible for unzipping the DNA?
Helicase
What phase of mitosis do the chromosomes move to opposite poles?
Anaphase
Tumor
What is the name of the phase represented by the picture in slide 2?
Anaphase
What DNA component is responsible for the coding of your genetic traits?
Nitrogenous bases
What is the name of the enzyme that glues the Okazaki fragments back together?
Ligase
In this phase, the nucleus condenses and chromosomes become visible. The spindle begins to form.
Prophase
What is the purpose of a cyclin protein?
What is the name of the phase represented by the picture in slide 3?
telophase
What is name of the overall shape of DNA and what type of strands do they contain?
double helix; anti-parallel
What is the name of the enzyme that lets DNA polymerase know where to start DNA replication?
Primase
What phase of the cell cycle does DNA replication take place?
S phase
Describe how the cell cycle repairs the body
What is the name of the phase represented by the picture in slide 4?
interphase
What is the difference between the covalent bond and hydrogen bond in a DNA molecule?
The covalent bond holds the nucleotides together and the hydrogen bond holds the base pairs/DNA molecule together
What is the difference between prokaryotic and eukaryotic DNA replication
Prokaryotic: The DNA exists as a single loop and begins at a single starting point and proceeds in two directions until the entire chromosome is copied.
Eukaryotic: Begins on dozens of places on DNA and proceeds in both directions until chromosome is copied
Describe how the animal cell and plant cell complete cytokinesis to form 2 daughter cells.
Animal cell: clevage furrow.
Plant cell: Cell Plate
What is the difference between an internal regulatory protein and an external regulatory protein?
Internal: allow the cell cycle to proceed only once certain processes have happened.
External:direct the cells to speed up or slow down cell cycle.
What is the name of the phase represented by the picture in slide 5?
Prophase
