Topic 5
What are the three Cytoskeletal filaments found in cells?
Actin, Intermediate Filaments, Microtubules
what are the three extracellular fibers
laminin, collagen, and elastin
what is made when there is excessive transcription
siRNA
what protein is responsible for synthesizing the leading strand during DNA replication
DNA polymerase
I am a cytoskeletal filament made up of tubulin
cytoplasm
What does dynamic mean, and what are the cytoskeletal filaments associated?
can be moved, it can move, and can be rearranged/restructured
collagen
what intermediate filament makes up mitotic spindles during mitosis
microtubules
DNA replication needs these proteins to keep the single stranded DNA from reannealing
single stranded binding proteins
I am a tight junction
between epithelial cells
What is this called: myosin is left in the tensile state, attached to myosin due to absence of ATP in a cell
rigor mortis
Where is tropocollagen made, and where is collagen fully assembled
endoplasmic reticulum and outside of the cell
what does "semi conservative mean"
the old strand is the template for the new strand
This basic protein is highly conserved and found in high quantities in the nucleus
histones
I am an importin bound to substrate and ranGTP
After Myosin cleaves ATP, what has to occur for myosin to reattach to Actin?
conformational shape change of the myosin head
these membrane bound glycoproteins bind carbohydrate ligands and is dependent on Ca2+
selectins
where in the nucleus can we find euchromatin
this protein has domains for proteoglycans, cell binding, and collagen
Fibronectin
I am a leukocyte experiencing rolling adhesion
blood vessel
This cytoskeletal filament subunit can be hydrolyzed to cause catastrophe
b tubulin
Leukocyte adhesion uses these proteins
selectins, integrins and ICAMS
nucleosome - 10nm fiber - 30nm fiber - chromosome
Focal adhesions and hemidesmosomes associate with this protein
integrins
I am an unfolded ribosome subunit
nucleosome
