developing a list of possible diseases or disorders based on the information you are given
differential diagnosis
learning objectives
preliminary possibilities
Kai's overwhelming energy and inability to focus can be identified as (a) .
chromosome pairs (one from each parent) having similar gene composition, size, and structure
chromatid
homologous chromosome
centromere
gene
What phase of mitosis is this cell in?
interphase
prophase
metaphase
anaphase
telophase
What phase of mitosis is this cell in?
(a)
During _____________, chromosomes are being pulled to the cell's poles after lining up in the middle.
anaphase
metaphase
telophase
cytokinesis
interphase
DNA replicates during (a) .
What would happen if the DNA of a cell didn't replicate during interphase?
the offspring cells would be missing a part and may not be able to perform a proper function
cells can use DNA replication to share parts and they can make up for a small miss by helping each other
TRUE or FALSE?
metastasis = a lump or mass of cells caused by an uncontrolled cell division
true
false
TRUE or FALSE?
benign = tumors that are generally considered harmless and will not spread to other parts of the body if not treated
true
false
(Write 2-3 sentences) What is an example differential diagnosis explanation that a doctor could use to explain Kai's condition to his parents?
What are some qualities of cells that doctors can look for when determining if cells are cancerous or not?
cell division
cell size and shape
nucleus
a different look from all other cells in the body
arrangement
These are the things that (a) are responsible for: driving cell reactions, providing defense, building structures, transportation, cellular activities, and movement.
The NF1 gene is found on chromosome 17 and carries the instructions to create a protein called neurofibromin. Neurofibromin regulates mitosis and works to prevent cells from growing and dividing in an uncontrolled way. The cells of individuals with NF1 divide out of control, leading to the creation of tumors. Given this information, which functional category would this protein best belong to?
cellular activities because the body can keep the cells from dividing more than needed and maintains homeostasis
movement because homeostasis is being maintained in the easiest and most possible way that it can without causing too much harm to the body
transportation because the cells from mitosis can help control growth
providing defense because the body can control the overproduction and fight
building structures because the structure of this gene helps the foundation of the protection
DNA ---> Proteins ---> (a)
Within a cell, DNA is housed in the ______________.
nucleus
ribosome
cytoplasm
nucleic acid
TRUE or FALSE:
translation, transcription
true
false
A, T, G, C are (a) bases.
A ____________ is a sequence of three mRNA bases that codes for one amino acid.
codon
anti-codon
codon wheel
DNA codon
DNA strand ---> ATC
find the mRNA and then translate it into an amino acid
(a)
Which mutation does not result in a frameshift mutation?
(a)
(Write 1-2 sentences) Predict what could occur to a gene if a base is substituted, inserted, or deleted. Consider the impacts of these changes on the reading frame and on the protein that is produced.
Circle the nucleotide in which the mutation happened (insertion).
List all possible treatments for Kai, as well as your ideas for his health over his lifetime.
