Question 1

Primary Ciliary Dyskinesia

Answer 1

Also known as Immotile Cilia Syndrome
-Cause problems of the cilia in the respiratory tract

-bronchiectasis
-a reversal of the thorax and abdominal organs
-sinus aplasia

Question 2

Lysosomal Storage Disorder

Answer 2

Specific lysosomal enzyme is absent or inactive, preventing digestion of certain cellular substances and allowing the to build up in cells

This allows substances to build to a harmful level which leads to widespread tissue weakness, injury, and death. There us no cure and the lifespan is typically severely shortened.

Disorder is inherited, members of a family with the disorder should have genetic evaluation about the risk of passing the disorder to children.

Question 3

Ribosomal RNA

Answer 3

Translates the instructions and provides the machinery needed for protein synthesis

Question 4

Messenger RNA

Answer 4

Carries the instructions for protein synthesis, obtained from the DNA molecule, into the cytoplasm

Question 5

Transfer RNA

Answer 5

Reads the instructions and delivers the appropriate amino acids to the ribosomes

Question 6

Type of energy production that occurs in the mitochondria with the Krebs cycle

Answer 6

Aerobic Metabolism

aerobic pathways occurring in the mitochondria and involving the citric acid cycle

Question 7

G0

Answer 7

Cell may leave the cell cycle & either remain in a state of inactivity or reenter the cell cycle at another time

RESTING PHASE

Question 8

G1

Answer 8

Cell begins to prepare for mitosis by increasing proteins, organelles, & cytoskeletal elements

PREPARE FOR DIVISION

Question 9

S Phase

Answer 9

Synthesis phase, when DNA synthesis or replication occurs and the centrioles begin to replicate

SYNTHETIC DNA REPLICATION

Question 10

G2

Answer 10

Pre-mitotic phase and is similar to G1 in terms of RNA activity and protein synthesis

PRE-MITOTIC PHASE

Question 11

M Phase

Answer 11

Cell mitosis occurs

CELL DIVISION
