. Discuss the principle of simple staining. What are the possible outcomes of staining a smear without heat-fixing it? Discuss the chemical mechanism of Gram’s stain. There are bacteria which cannot be stained by Gram’s stain method of staining. Why? In the process of staining, for example, you run out of Crystal violet can you […]
What is the total magnification of a sample with an ocular lens power of 15X and using a 40X objective lens?
This question has two parts: The ability of adult humans to digest milk is dependent on the persistence of the enzyme lactase into adulthood. Most humans stop producing lactase after infancy but a small portion of the population retains this ability. Non-persistence of lactase is a Mendelian trait that is autosomal recessive. Give the genotypes […]
You are a xenobiologist (you study non-earth life) and you want to be the first person to read the entire genome of the Na’vi people from Pandora. You must first make lots of copies of their genes, fragment them, then read the order of the nucleotides. What biotechnology tools will you use? (In order of […]
What is the correct amino acid sequence that would be associated with the following mRNA sequence? ( 2 pts) AUG UCC GGC UCU CCC AAG Suppose the fourth codon of in the above was changed to UGA. Give the amino acid sequence that would result and describe what happens to the protein.
A woman is homozygous recessive for freckles and a man is homozygous dominant for freckles. Freckles are dominant, no freckles are recessive, and this is an autosomal trait. What is the likelihood of their children having freckles? (Hint: you may want to do a Punnett square on scratch paper
discuss the Bioethical Dilemma for this unit: Gene Therapy Research Your post should consist of information that relates to these three aspects of the dilemma: The history of the issue/dilemma The opposing sides of the dilemma Any Biblical passages or principles that inform or guide mankind to help resolve or make practical sense of the […]
Research the discovery and clinical application of calcitonin gene-related peptide. how does this peptide provide an example of the functional significance of alternative splicing of mRNA
Would you expect the salivary gland cells of blow flies to possess the haploid or diploid number of chromosomes for this species? Why? In which type of cells do you expect synapsis to occur
Complete the table below that describes different types of chemical bonds. Bond Name Type of interaction between atoms Sharing of electrons Polar Covalent Bond Equal Sharing of electrons ionic Bond Unequal sharing of electrons results in regions of opposite charge in a molecule. The regions of opposite charge cause these molecules to bond to each […]
