Up to 60% of all medicines used today exert their effects by influencing these structures in the cell membrane.
What are G proteins?
200
The longest of the mitotic stages.
What is metaphase?
200
This process leads directly to the formation of gametes. (Concept 13.2)
What is gametophyte mitosis?
200
When a disease is said to have this, it means that both genetic and environmental factors contribute to the disease. (Concept 14.4)
What is a multifactorial basis?
200
This determines the nucleotide sequence of the newly synthesized strand during DNA replication. (Concept 16.2)
What is the nucleotide sequence of the template strand?
300
This inhibitor could be used to block the release of calcium from the endoplasmic reticulum.
What is phospholipase C?
300
The microtubules of the spindle originate here during mitosis in both plant and animal cells.
What is a centrosome?
300
A display of every pair of homologous chromosomes within a cell, organized according to size and shape. (Concept 3.2)
What is a karyotype?
300
This is best described by a gene region present on the Y chromosome that triggers male development. (Concept 15.2)
What is SRY?
300
Relieving strain in the DNA ahead of the replication fork. (Concept 16.2)
What is topoisomerase?
400
Large molecules to which several relay proteins attach to facilitate cascade effects
What are scaffolding proteins?
400
The formation of a cell plate is beginning across the middle of this type of cell and nuclei are forming at opposite ends of the cell. (Which type of cell and what phase)
What is a plant cell undergoing cytokinesis?
400
During this phase the synaptonemal complex disappears. (Concept 13.3)
What is the late prophase of meiosis I?
400
The mechanism for the production of genetic recombinants. (Concept 15.3)

400
This is how many more genes there are in the haploid human genome than in a typical bacterial genome. (Concept 16.3)
What is 1000X?
500
It's DNA and organelles are fragmented, the cell shrinks and forms blebs, and the cell self-digests.
What is the description of apoptosis
500
A protein maintained at constant levels throughout the cell cycle that requires cyclin to become catalytically active.
What is Cdk?
500
Independent assortment of chromosomes occurs in this phase. (Concept 3.3)
What is meiosis I?
500
This is required for chromosomes to undergo inversion or translocation. (Concept 15.4)
What is chromosome breakage and rejoining?
500
Histone H1 is not present in the nucleosome bead; instead it is involved in the formation of higher-level chromatin structures. (Concept 16.3)
