Post by: Mira8642 on Oct 29, 2011
Bob noticed that the pollutant ochratoxin was causing cell death by altering the filaments and fibers within the cell. What part of the cell is this poison likely disrupting?
 A. Lysosomes. 
 
 B. Cilia. 
 
 C. Vacuoles. 
 
 D. Cytoplasm. 
 
 E. Cytoskeleton.

If a DNA molecule contained the base sequence 5’ TATCGTC 3’ unzipped for replication, what would be the sequence of its complementary NEW strand? 
 A. 3’ATAGCTG 3’ 
 
 B. 5’ATAGTAG 3’ 
 
 C. 5’ATAGCTG 3’ 
 
 D. 5’ATAGCAG 3’ 
 
 E. 3’ATAGCAG 5’ 

If a DNA strand with the base sequence CAGCAT were to unzip and be replicated, what would be the base sequence of its OLD complementary strand and its NEW complementary strand?
 A. Old = CAGCAT, new = GTCGTA 
 
 B. Old = GTCGTA, new = GTCGTA 
 
 C. Old = TAGCAT, new = TAGCAT 
 
 D. Old = ATGCTG, new = ATGCTG 
 
 E. Old = CAGCAT, new = ATGCTG

Sarah, you missed this one ;)

 B. Old = GTCGTA, new = GTCGTA
