NUR 631 Final Exam Prep -Questions and Verified
Answers| 100% Correct-
Nucleus
control center of the cell; directs cell activities
Nucleolus
membrane-bound organelle that manages cellular functions; contains DNA
DNA
found in nucleolus; made up of nucleotides, sugar(deoxyribose), phosphate group, and 4
nitrogenous bases (ATCG)
4 nitrogenous bases in DNA?
Adenine, Thymine, Cytosine, and Guanine
RNA
found in cytoplasm
4 nitrogenous bases In RNA?
Adenine, Uracil, Cytosine, Guanine
mRNA
plays a crucial role in the process of protein synthesis in cell; carries temp copy of genetic
information from nucleus to ribosomes
What is the function of tRNA in protein synthesis?
Helps in the actual assembly of amino acids into a protein at the ribosome.
What role does tRNA play in relation to mRNA?
Interprets the genetic code in mRNA.
,plasma membranes
flexible boundary between the ell and its environment
True
does the plasma membrane have an amphiphilic feature?
True or false?
Ribosomes
what part of the cell makes proteins?
Lysosomes
what part of the cell's function is auto digestion and intracellular digestion?
Golgi complex
where do lysosomes originate from?
Mitochondria
the powerhouse of the cell; makes energy for cell
Endoplasmic reticulum
has smooth and rough structures in the cell
Rough ER
studded with ribosomes; function is protein synthesis
Smooth ER
absence of ribosomes
Golgi apparatus
flattened smooth membrane; has secretory vesicles and cisternae
Function of the Golgi apparatus?
, modifying, sorting, and packaging of proteins
Lipid bilayer
prevents water soluble molecules from crossing membrane
Apoptosis
programmed cell death
Necrosis
tissue death; considered pathological
Coagulative
what type of necrosis is a denaturation of proteins that affects the kidneys?
Fat
what type of necrosis is caused by lipases and is "soap-like?"
Liquefactive
what type of necrosis typically affects neurons/glial cells in the brain, tissue becomes soft, and
forms cysts?
Caseous
which type of necrosis resembles clumpy cheese, cells denature but debris is walled off?
dry gangrene
blood supply by the tissue is cut off; area becomes dry, shrinks, and turns black
wet gangrene
what type of gangrene occurs when bacteria invades the tissue?
BRCA 1 & BRCA 2
