Genetic information in a DNA molecule is contained:
What is bases
100
The “t” of tRNA stands for:
What is transfer
100
Every form of life either is a single cell or is composed of multiple cells, except:
What is a virus
100
a sequence of enzymatically controlled reactions in which the product of one reaction becomes the substrate for next
What is metabolic pathway
100
A cell “needs” to move a vesicle from one side of the cell to another.
What is proteins that comprise the cytoskeleton contract and facilitate movement of vesicles
200
Contains two complementary strands:
What is DNA
200
__________ has an amino acid attachment site, mRNA attachment site, and an anticodon
What is tRNA
200
Besides having a membrane bound nucleus and being larger, eukaryotic cells differ from prokaryotes in that eukaryotes:
What is they typically exist as multicellular organisms
200
When yielding energy, matter moves from a more-ordered state to a less-ordered state. This is known as:
What is the second law of thermodynamics
200
A plant cell “needs” to make cellular energy (ATP).
What is glucose is catabolized into water and carbon dioxide in mitochondria in order to form ATP.
300
The type of biological study that was exemplified through the discovery of DNA structure is called:
What is molecular biology
300
The number of DNA bases necessary to code for an amino acid is __________; this sequence of bases is called a __________.
What is 3 and codon
300
In osmosis, water moves across a semipermeable membrane:
What is toward an area of higher solute concentration
300
carbon from glucose
What is the source of carbon dioxide that we exhale?
300
An animal cell “needs” to recycle a bunch of worn-out proteins.
What is enzymes to drive these reactions need to be produced (DNA → mRNA → ribosomes on roughER → translation). Proteins are then tagged in the Golgi for their final destination (lysosomes) where the enzymes break down (catabolize worn out proteins).
400
A gene can be characterized as:
What is a series of DNA bases that contain information for production of a protein
400
Some non-coding DNAs have regulatory functions. These regulatory mechanisms include promoters and enhancers, micro-RNAs, and __________________.
What is alternative splicing
400
According to the fluid mosaic model of membrane structure, a cell’s membrane is made up of:
What is a bilayer of phospholipids with proteins interspersed in it that have fairly free lateral movement
400
The components of ATP?
What is ribose sugar, adenine and phosphate groups
400
A cell “needs” to produce the enzyme lactase.
What is lactase needs to be produced (DNA → mRNA → ribosomes on rough ER → translation). Lactase is then tagged in the Golgi for its final destination
500
A DNA nucleotide is composed of:
What is a phosphate group, a deoxyribose molecule, and one of four bases
500
The process of translation
What is mRNA binds to the ribosome’s small subunit; a tRNA with the appropriate anticodon sequence binds to mRNA; polypeptide chain is elongated
500
The process of eating pasta
What is you eat pasta for dinner and digest the starch in it into glucose. The glucose is now in high concentration in the cells of your small intestine relative to the concentration of glucose in your bloodstream. With the help of a transport protein, the glucose diffuses across the plasma membranes of your intestinal cells and into your bloodstream.
500
During the Tour de France, bikers that are undergoing a difficult stretch of hill climbing are mostly using __________________as an energy source
What is glycolysis
500
A liver cell “needs” to make triglycerides and cholesterol
What is enzymes to drive these reactions need to be produced (DNA → mRNA → ribosomes on roughER → translation). Proteins are then tagged in the Golgi for their final destination and moved to smooth ER where they are part of metabolic pathways to produced triglycerides and cholesterol.
