Water has which property or properties? correct answer: Hydrophilic Forms hydrogen bonds Ocean acidification is resulting due to correct answer: Global release of CO2 through the use of fossil fuels Which other element (besides Carbon) is often suggested a...

Which protein influences the ability of RNA polymerase to transcribe genes? correct answer: Transcription factors Mitosis results in the formation of two genetically identical daughter cells. This is because correct answer: all the genetic material is duplicated then segregated equally to the daughter cells. Which of the following is an overgrowth of cells that serves no useful purpose? correct answer: Tumor Why must the life cycle of sexually reproducing species alternate between ha...

How many hydrogen bonds are there between an A and its paired nucleotide? correct answer: 2 T/F: The genetic code for the conversion of mRNA codons to proteins has redundancy correct answer: True List one type of post-translational modification correct answer: Proteolysis, Glycosylation, Phosphorylation. For DNA Polymerase III to work which of these components has to act first? correct answer: Primase Draw the sugar in DNA and label the carbons as discussed in the lecture. Then c...

The paramecium discussed in class contained an organelle called the contractile vacuole. This is the presumed precursor of the: correct answer: kidney A cell that is anchorage-dependent for growth will also exhibit contact inhibition. correct answer: true In your own multicellular body, cells with different functions have different DNA. correct answer: false The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. correct answer: true The par...

The association of ribosomes with _____ invaginations would support the _____ theory. correct answer: membrane, endomembrane After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walks is? correct answer: filapodia, lamellipodia, cell muscle, retraction fiber T/F It is presumed that the peroxisomes evolved in these primitive, proto-eukaryotes to remove oxygen, which was toxic to the primitive cells. correct answer: true T/F In an extant prok...

Comparing a single-celled eukaryotic organism with a multicellular organism such as yourself identify the major difference from the list below. A. Escape from predator B. Finding a mate C. Division of Labor D. Find it's own food E. Nucleus correct answer: C. Division of labor The paramecium swims by way of using a flagella. correct answer: FALSE The contractile vacuole of the paramecium is possibly an evolutionary precursor of the kidney. correct answer: TRUE The paramecium dis...

The stage of meiosis where 'crossing over' occurs. correct answer: Prophase 1 A mutation that you could pass on to your offspring would occur in the correct answer: Germ cells Most mutations that occur in our genomes are (neutral, beneficial, deleterious) correct answer: Neutral Which type of mutation would most likely have dramatic effects on the gene of interest? correct answer: Frameshift or Nonsense mutation What is the prob. of a child having same phenotype as first parent...

When the presynaptic cell contacts a muscle cell, the synapse area is called a motor end plate. correct answer: TRUE Briefly explain why the action potential flows only from the axon hillock to the terminal web. correct answer: During the course of an action potential there is a refractory period that makes sure the action potential can't trigger backwards by the use of caps on gated sodium channels. The caps close and keeps the action potential flowing in one direction. How do the glia...
