Accessibility only benefiting a small minority is a myth. Who does accessibility benefit? (1) - 1. Everyone: websites work better across platforms, SEO is improved, anyone can acquire a disability at any time, and those with disabilities are a sizable minority of the overall population Accessibility being a short-term project is a meth. What is the truth? (4) - 1. Accessibility must be embedded in the process 2. The company culture must commit to accessibility 3. Resources and full-time jo...

What is the difference between habituation and adaptation? How could you tell if a decrease in the behavioral response of an animal is due to habituation or adaptation? - Habituation: Non noxious stimuli at low frequencies to stop an animal from responding, (reduce quantal content, synaptic pruning), homo-synaptic depression Adaption: What types of molecular events are likely to underlie short term memory? Long term memory? Forgetting? - Short Term: Increase quantal content, increase Ca2+,...

What are the three main components of the cytoskeleton and what are their main functions? - Microfilaments: made of actin; determines the shape of cell surface and is important for the movement of the cell Microtubules: made of alpha and beta dimers ; act as tracks for vesicles and other properties to move about the cell with motor proteins Intermediate filaments: made of various proteins + rope-like fibers; provide mechanical strength The actin filament and microtubules carry stuff by "w...

What are the three main components of the cytoskeleton and what are their main functions? - Microfilaments (actin): sense the environment and direct movement Intermediate Filaments: maintain cell shape/structure, anchor organelles Microtubules: for transport What are the main similarities and differences between the three components of the cytoskeleton? - Similarities: -important for cytoskeletal structure -charged ends; form a highway for motor protein Differences: -size and function

What are the three main components of the cytoskeleton and what are their main functions? - Microfilaments: movement microtubules: transport of cellular materials intermediate: support What are the main similarities and differences between the three components of the cytoskeleton? - all are important for cytoskeleton structure differ in size Describe how the assembly of actin filaments is regulated. Include both the role of associated protein and monomer concentration. - Rac/Rho/CDC43 tri...

What is the molecular genetic definition of a gene? - A gene is a section of genomic DNA that codes for a function product and includes all of the sequences that regulate its expression. Is it possible to have a mutation that normally causes disease and not show any symptoms? Explain your answer in a sentence or two - Yes, the expression of a phenotype is often a combination of genetics and environment and a mutation might not show any phenotype in a particular environment. What are three...

Why does the organization of the eye guarantee that we have a blind spot? Why can't we normally detect the blind spot? - The blind spot occurs due to the lack of photoreceptors where the optic nerve and blood vessels exit the eye. Our brain fills the blind spot in by using information that surrounds the blind spot area using ipsilateral and contralateral visual input. What is different about the fovea and the rest of the retina? Why is visual acuity best when images fall on the fovea? - Th...

What are the main organs affected by cystic fibrosis? - Lungs, any organ that has epithelial cells, mucus, and secretory system which requires regulation of that mucus Describe the main function of the CFTR protein and how it is regulated. - responsible for regulating the proper flow of chloride and sodium (a component of salt) in and out of the cell membranes in the lungs and other organs. It is regulated by its cytosolic domains: two nucleotide binding domains (NBDs) and a regulatory (R) ...

Describe the signals and mechanisms required for import into the peroxisome. - -peroxisomal targeting sequence -peroxisomal import machinery (Pex5 receptor- first thing that binds on and recognizes signal sequence) Describe the functions of the SRP (signal recognition particle). - -Recognizes hydrophobic amino acid sequence to stop translation, brings sequence to ER. -Binds to the ribosome with an ER signal sequence and stops translation of the protein, then docks the ribosome to a prot...

Which 2 groups originally classified neurons by morphology? - 1. Golgi 2. Ramon y Cajal What was the first technique used to visualize the neuron? - Golgi staining technique How does golgi staining technique work? - If you put brain tissue into solution with silver nitrate for a few days the solution goes into neuron and makes it visible What debate occurred between Golgi and Ramon/Cajal - - Golgi thought that the nervous system was one connected network, which is wrong - Ramon and Caj...

Design an experiment to test if a protein really has a signal sequence that can target it to the nucleus. - Use GFP so you can watch the protein move in real time Describe an experiment to show that a candidate sequence is necessary for nuclear import. - Using a protein that normally enters the nucleus, mutate the candidate sequence then see if the labeled protein still enters the nucleus. If it was necessary, the protein will no longer enter the nucleus. Describe an experiment to show tha...

If all cells in an organism have the same genomic DNA, what makes a liver cell different than a neuron? - translation of different proteins what DNA gets expressed as protein-protein interactions What are the nucleotides that make up DNA and how do they interact? What are the benefits of having two strands of DNA rather than a single sequence? - Adenine, Guanine, Cytosine, Thymine. They are H-bonded together. What is the definition of a gene? - a unit of heredity which is transferred fr...

Define learning, memory, and recall(separately). - learning: the acquisition and forming of new connections memory: remembering of events thst occured in past. Using the connections previously made to repeat a task or performance in similar way recall= to bring memory from long term to short term/ working memory Describe the major differences between declarative and non-declarative memory - declarative = facts and events nondeclarative = procedural memory, habits Describe the basics of f...
