1. Genomics is the study of:
a. The structure and function of mutations and how they alter genetic traits.
b. Genes and the DNA sequences between genes and how they determine development.
c. The information provided by computer programs which analyzes mRNA.
d. The human genome as compared to other vertebrate genomes.
2. Microarrays are a very useful tool in genomics because they:
a. Help scientists examine intergenetic DNA by separating it from genes.
b. Provide a unique promoter region for polymerase chain reactions.
c. Allow scientists to examine thousands of genes all at once.
d. Decrease the time it takes for scientists to make copies of DNA.
3. Generally, every cell in our body contains the same 20,000 (or so) genes. However, cells in our body are different from each other because they:
a. Have different genes turned “on” or “off” to support different functions.
b. Contain different copies of genes for different functions.
c. Provide different nucleotide bases for each developmental function.
d. Function differently based on varying proteomics.
