loeys-dietz syndrome (type 2b) is a human genetic disorder associated with mutations in the lds2b gene. researchers have proposed that the lds2b gene produces a growth factor receptor protein that regulates cell signaling pathways. the predicted product of the gene is 565-amino acid protein with structural regions that bind to signaling molecules, span the plasma membrane, and has protein kinase activity. protein kinases are cellular enzymes that transfer phosphate groups from atp to target proteins. calucate the minimum number of nucleotides required in the coding region of the lds2b mrna molecule to produce and terminate the 565-amino acid polypeptide. explain how you arrived at your answer

c.) polymerase chain reaction

- "unlike the original dna fingerprinting method, dna profiling does not use restriction enzymes to cut the dna. instead it uses the polymerase chain reaction (pcr)? to produce many copies of specific str sequences. pcr is an automated procedure that generates lots of copies of a specific sequence of dna."

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
