What is the combination of an electrical gradient and a concentration gradient called?
What is an electrochemical gradient?
The AUC and AUA codons in mRNA both specify isoleucine. What feature of the genetic code explains this?
What is redundancy?
Credited as the father of microbiology, this scientist designed the first microscope.
Who is Antonie van Leeuwenhoek?
Aside from sunlight, these two components are needed to begin photosynthesis.
What are 6 CO2 + 6H20?
Usually performed by the cell's vacuoles, this involves the moving of materials outside of the cell.
What is exocytosis?
___________ are changes to the order of nucleotides in a segment of DNA that codes for a protein.
What are gene mutations?
The pea plants used in Mendel’s genetic inheritance studies were diploid, with 14 chromosomes in somatic cells. Assuming no crossing over events occur, how many unique gametes could one pea plant produce?
What is 128?
If black and white true-breeding mice are mated and the result is all gray offspring, what inheritance pattern would this be indicative of?
What is incomplete dominance?
What happens to the membrane of a vesicle after exocytosis?
What is It fuses with and becomes part of the plasma membrane?
A scientist randomly mutates the DNA of a bacterium. She then sequences the bacterium’s daughter cells, and finds that the daughters have many errors in their replicated DNA. The parent bacterium likely acquired a mutation in which enzyme?
What is DNA Polymerase?
This duo demonstrated that DNA was the "transforming principle".
Who are Oswald Avery and Maclyn McCarty?
This photosystem involved the photosynthetic electron transfer chain.
What is photosystem I?
This process involves the expelling of more cations than are taken in.
What is the sodium-potassium pump?
What is the main prerequisite for clearance at the G2 checkpoint?
What are an accurate and complete DNA replication has occurred?
What phase of mitotic interphase is missing from meiotic interkinesis (before meiosis II)?
What is s phase?
The ABO blood groups in humans are expressed as the IA, IB, and i alleles. The IA allele encodes the A blood group antigen, IB encodes B, and i encodes O. Both A and B are dominant to O. If a heterozygous blood type A parent (IAi) and a heterozygous blood type B parent (IBi) mate, one quarter of their offspring will have AB blood type (IAIB) in which both antigens are expressed equally. Therefore, ABO blood groups are an example of:
What are multiple alleles and codominance?
This form of passive transport moves molecules across a cell membrane from an area of high concentration to an area of low concentration with the help of specialized proteins like channel proteins or carrier proteins

What is all of the above?
Credited with an element named in his honor, this chemist created the Periodic Table.
Who is Dmitri Mendeleev?
This theory is an attempt to explain the presence of the chloroplast in plant cells.
What is the endosymbiotic theory?
This type of transport mechanism can bring whole cells into a cell.
What is phagocytosis?
