1. The cystic fibrosis transmembrane conductance regulator (CFTR) causes
abnormalities in Cl- transport. Water movement via osmosis through epithelial cells
follows salt movement. With the abnormalities in Cl - transport there is not enough
1. Roux performed a procedural error. By not removing the dead cell from the living, unharmed cell, the
embryo could not develop correctly. Cells are reductionist, when the dead cell was not separated from
the living cell, there was a flaw
Ultimately, enzymes are proteins that speed up certain chemical reactions such as respiration,
photosynthesis, DNA replication, and protein synthesis. In the process, enzymes are not altered, used up,
or make more product, enzymes simply i
There are two different types of cells prokaryotic and eukaryotic cells. Prokaryotic cells are simpler
than eukaryotic cells. Prokaryotic cells are thought of to be bacteria cells. Eukaryotic cells are more
complex and are cells of animals
1) A set of chemical reactions occurs within a cell when a molecule is connected to another cells
membrane via signal transduction. Signal transduction occurs when DNA is integrated into a
bacterial cell by a virus containing a viral vector. The route sig
1) Interphase is the first phase in the mitotic sequence. Within interphase are more steps
that occur. The first one to occur is the G1 phase. This phase doesnt have much happen
other than cell growth and preparation for DNA replication. The S phase comes
1) The cisternal side of the Golgi membrane would most likely have similar characteristics to that of
the extracellular side and not the cystolic. The Golgi membrane and the cisternal are relatively
close to each other. They touch and become the secretion
INTRODUCTION TO THE STUDY OF CELL & MOLECULAR
Present a brief outline of the early history of Cell Biology.
Familiarize students with the basic properties of all cells.
Describe the differences between prokaryotic and eukaryot
BIOENERGETICS, ENZYMES, AND METABOLISM

1) Meiosis results in four daughter cells. These cells contain half the number of chromosomes as all
other cells in the body. It is the means for reproduction in animals. Stages of meiosis consist of I.P.M.A.T.
Interphase is a rest period. In prophase I t
1) Semiconservative replication is the mechanism all known DNA is replicated by. It is when
replication results in two copies of DNA. An original and a copied. It is different because
conservative replication would result in two original DNA strands and t
The RER creates membrane proteins and secretory proteins. It also
makes membrane from phospholipids and proteins. Its main function

Translation directly follows transcription of mRNA. The steps are similar and include initiation,
elongation, and termination. Initiation is started by the reading of a start codon. In eukaryotes the
sequence is AUG. The A in the sequence allows for methi
All of the transcription factors include the TATA region, TBP, transcription factor II, transcription factor
IIH, and TTF1. The TATA region is where DNA is read and transcription started. TBP is the protein that
allows binding to the TATA region. TFII aid
DNA contains nucleosome which are structures surrounding histones. Histones are proteins at
specific locations and are the site of replication in eukaryotic cells. The DNA attaches to an enzyme
called helicase which can unwind the DNA at breakneck speeds
