BioChem
On the pH scale, this number represents a neutral solution like pure water.
These macromolecules are the body’s main source of quick energy and include sugars and starches.
Carbohydrates
In this phase, chromosomes line up in the middle of the cell.
Metaphase
The repeating sequence of cell growth, DNA replication, and division that most cells undergo.
The Cell Cycle!
True or false, Mitosis is a form of asexual reproduction.
True!
Because water is this type of molecule, it has a slightly positive end and a slightly negative end.
Polar
The monomers of proteins that determine their structure and function.
Amino Acids
In this phase, chromatin condenses & is visible as chromosomes (in X’s).
Prophase
What is the purpose of the cell cycle?
Growth & Repair
A form of reproduction that produces genetically identical offspring.
Asexua Reproduction
This biological molecule speeds up chemical reactions in living things.
An enzyme.
This macromolecule stores genetic information and includes DNA and RNA.
Nucleic Acids
In this phase, sister chromatids separate, pulling away from each other and becoming individual chromosomes.
Anaphase
This is the longest phase of the cell cycle, when the cell grows and replicates its DNA.
Interphase
What two cells come together during the process of fertilization in sexual reproduction?
Sperm and Egg Cells
A solution with a pH of 2 is strongly this.
Acidic
These macromolecules provide long-term energy storage and make up cell membranes.
Lipids
The division of the cytoplasm into 2 individual cells.
Cytokinesis
Cell cycle checkpoints help prevent this dangerous outcome when cell division becomes uncontrolled.
Cancer
The total number of chromosomes in a human somatic (body) cell.
46 (23 pairs)
This property allows water to move upward through plant stems due to attraction between water molecules and other surfaces.
Adhesion
This property of water allows insects like water striders to walk on its surface.
Surface Tension
In this phase, chromosomes decondense and start to look like chromatin again (threadlike instead of rodlike), and the nuclear membrane reforms around chromosomes at each pole.
Telphase
Name the THREE "phases" that occur during Interphase, this is where the cell grows and DNA is replicated.
G1 Phase, S Phase, and G2 Phase
This region holds sister chromatids together and is the attachment point for spindle fibers during cell division. (the center of the chromosome)
Centromere
