MICR 2123 Exam #1 Questions with complete solutions
Electron beams can not be used to resolve images of objects. T/F? Correct Answer-False 
 
In all types of electron microscopy, electrons pass through the specimen. Correct Answer-False 
 
This type of light microscopy can be used to view very thin cells or flagella. It does that by using this property of light. Correct Answer-Dark field; Light scattering 
 
In this type of microscopy, light is delayed by passing through the sample and so objects look as if they are out of phase. It employs this ...

MICR 3033 Exam #4 Questions with complete solutions
All cells that make up an organism contain the exact same DNA sequence (genome) however individual cell-types look and function very differently. Why? Correct Answer-each cell-type expresses a unique set of genes of the genomic DNA. 
 
Speaking of genotype and phenotype how are these terms defined? Correct Answer-the genotype defines the genetic information (gene) and the phenotype the outcome of gene expression. 
 
Which of the following describes a functional gene? Correct Answer-a gene is def...
