What are the functions of a dehydrogenase, kinase, and decarboxylase?
-Dehydrogenase: removes 2 H atoms
-Kinase: transfers P group to substrate
Decarboxylase: removes COO- or COOH
Independent assortment is the result of
the random and independent way in which each pair of homologous chromosomes lines up at the metaphase plate during Meiosis I
What is the difference, if any, between the lytic and lysogenic cycles?
A. Lytic cycle kills the host, lysogenic cycle integrates DNA
B. Lysogenic cycle kills the host, lytic cyle integrates DNA
C. Both cycles kill the host
D. Both cycles integrate DNA
E. Both cycles integrate DNA and kill the host
A. Lytic cycle kills the host, lysogenic cycle integrates DNA

Once dimerized, how do receptor tyrosine kinase proteins initiate a cellular response?
-ATP transfers phosphate to tyrosine kinase regions
-relay proteins bind to the tyrosine kinase regions and become activated
-Cellular response produced
Eukaryotic cells can control gene expression by
histone acetylation of the nucleosome

A. As an endonuclease, it cuts DNA
B. A piece of RNA complementary to a specific sequence in the genome
C. Facilitates target recognition
A. As an endonuclease, it cuts DNA
What is my favorite BIOL-K101 concept?
