Pltw Medical Interventions Unit 1 (Pltw Medical Interventions Unit 1) Solved 100% Correct!!

DNA Sequencing {Ans: The DNA is placed in order by size (smallest to largest) using gel electrophoresis or a similar method. It is then tagged by color (using fluorescent markers on the stoppers of the DNA) as to what nucleotide it represents. The nucleotides in size order are the DNA sequence. The bacteria can be identified using BLAST}Oval Window {Ans: Connects middle ear with the upper half of the cochlea. Transfers vibrations.}Ossicles {Ans: Form the mechanical links between the tympanic membrane and the inner ear. They deliver sound vibrations to the inner ear and amplify sound.}Ribosomes {Ans: Produce proteins}Capsule {Ans: Most outer layer of the cell, protects it from phagocytosis (white blood cells)}Middle Ear {Ans: The intermediate portion of the ear containing a chain of three ossicles that extends from the tympanic membrane to the oval window and transmits vibrations to the inner ear}Sensory Hair Cells {Ans: Vibrate inside of the cochlea generating the nerve signals}Plasma Membrane {Ans: Found in the envelope, protects the cell and controls what goes in and out.}Recombinant DNA {Ans: A DNA molecule made in vitro with segments from different sources}Vectors {Ans: Vehicles for DNA to
