BIOL 133 Week 3 Chapter 5 – Study Questions How are the membrane components oriented? Molecules move from a high to low concentration in What is the first step in Na -K pump? The impermeability of cell plasma membranes is a major barrier to using drugs to kill tumor cells or affect cells transgenically. CPPs are peptides that were discovered to have the ability to transport themselves (and even attached cargo) into cells. How they get into cells is still a mystery, but CPPs all have multiple...

BIOL 133 Week 3 Chapter 4 Study Questions _________________ prevent material from moving in or out of the brain’s capillaries When comparing prokaryotes and eukaryotes, flagella The shape of the cell is predominantly maintained by the Decondensed chromatin is located within the Cardiac muscle requires junctions that allow electrical signals through. Cardiac muscle also relies on calcium to contract. What junction is involved and what organelle stores calcium? If an integrin protein is mutated...

BIOL 133 Week 16 Chapter 20 Study Questions When a gene is passed to bacteria of a different species that brings with it an important feature, the resulting bacteria would provide complications in determining ________. The only taxonomic name not capitalized is the ________. Evidence has been gathered over the years that indicate mitochondria and chloroplasts were once bacteria. This idea is termed What is the proper way of writing the scientific name for humans? The idea of maximum parsimony de...

BIOL 133 Week 15 Chapter 19 What is the only way to introduce a new allele into a species? In South America, there is a specific type of frog where the male uses a loud call in order to attract females, even though this makes him more likely to be found by a predator. This is an example of The accumulation of mutations in a population over generations leads to If alleles that cause disease are constantly being selected against, why would there be any disease-causing alleles in a population over...

BIOL 133 Chapter 16-wk 12 Study Questions A gene is made up of three exons (numbered consecutively) with two introns (intron 1 between exons 1 and 2 and intron 2 between exons 2 and 3). What would happen if there were a mutation at the 3’ splice site of intron 1? _________ is the first protein to bind to mRNA to being the initiation of translation. In eukaryotes, where would a protective modification be found on mRNA? The portions of the mature mRNA where RNA-binding proteins can attach in or...

BIOL 133 Week 1 Chapter 1 Study Questions A decrease in blood water levels is detected in the brain. The brain sends signals to the pituitary gland to release hormones that communicate with the kidney to reabsorb water, which will increase blood water levels. This represents what life property? When a sperm uses chemical signals to navigate the swim towards the egg, it is a positive response. This is a form of When the brain, spinal cord, and nerves of the body communicate with each other, it r...

BIOL 133 Week 13 Chapter 17 Study Questions An individual may have a mutation that causes them to break down a drug much more quickly than normal people. They were then provided with a higher dose, which was effective in treating the disease. This is an example of ________. Isolating all of the RNA out of an organism, subjecting it to reverse transcriptase, and then cloning all of the resulting DNA into plasmids is the process of creating A change in the level of an individual protein in a dise...

BIOL 133 Week 11 Chapter 15 Study Questions What unusual feature does RNA polymerase II have in transcription termination? The type(s) of RNA that are directly involved in translation are which of the following. Select all that apply Basal transcription factors recruit RNA polymerase which combine together to form the ________. Elongation factors provide energy for translation by hydrolyzing what type of molecule? The codon AUG specifies the amino acid methionine. What would the tRNA anitcodon ...
