Mitosis
Put all the phases of Mitosis in order.
What is the prophase, prometaphase, metaphase, anaphase, telophase and cytokinesis?
True or False: Cell division allows for the reproduction of cells, growth of cells, and tissue repair.
What is true?
What do animal cells communicate through?
What is gap junction?
G-proteins bind to the _ side of the cell receptor
What is the cytoplasmic side?
The "cause" for something to happen is the ____.
What is stimulus?
What phase does the chromosomes meet up in the middle.
What is the Metaphase?
A disease where body cells grow and divide uncontrollably, damaging the parts of the body around them.
What is cancer?
Insulin signaling is what kind of signaling?
What is endocrine signaling?
What are the three steps of signal transduction
What is Reception, Transduction, and Response?
The process of which the response is increased.
What is positive feedback loop?
How do we count the number of chromosomes?
What is by counting the number of centromeres?
DNA wraps around what type of proteins?
What is histone?
Antigen presenting cells communicate to T cells through _
What is direct contact?
What does the receptor cell bind to in reception?
What is the ligand?
Describe homeostasis.
What is the state of relatively stable internal conditions?
What stage does this describe? The proteins that hold the sister chromatids together are being broken down and pulling them to opposite sides. The cell is then elongating.
What is anaphase?
Describe a prokaryotes genome, describe a eukaryotes genome.
Prokaryote: What is singular, circular DNA?
Eukaryote: What is one or more linear chromosomes?
What are the characteristics of the second messengers?
What are small, polar, hydrophilic, molecules or ions?
Specialized proteins with the ability to bind the nucleotides guanosine triphosphate (GTP) and guanosine diphosphate (GDP)
What is the G-protein?
When you get cut, your skin cells release hormones that signal platelets to come and stop the bleeding. Platelets then release more hormones that signal even more platelets to help stop bleeding. The hormone signals continue until the cut is closed.
What is positive feedback loop?
How many chromosomes are in elephants?
What is 56 chromosomes?
What terms does this describe: "Pair of chromosomes that are the same length, centromere position, and carry the same genes."
Homologous Chromosomes
This process is signal producing enzymes and signal receptors let these organisms distinguish themselves from others and wait until there is enough to stop or overcome a larger organism.
What is quorum sensing in bacteria?
Step of signal transduction is the process of activation of a series of proteins inside the cell from the cell membrane.
What is Transduction?
Which of the following is an example of negative feedback?
A. Childbirth contractions via oxytocin release
B.Lactation via prolactin production
C.Thermoregulation via sweating
D.Ovulation via the luteinizing hormone (LH) surge
E.Blood clotting via fibrin action
What is C?
