Heredity and Molecular Genetics
100
Something we detect with our senses.
What is Observation
100
The basic unit of structure capable of performing the functions of life.
What is a Cell
100
Organisms that produce their own organic compounds (food). One way they do that is by undergoing photosynthesis.
What is an Autotroph
100
Process in which the nucleus of a eukaryotic cell divides.
What is Mitosis
100
The science of heredity.
What is Genetics
200
A special type of scientific investigation performed under controlled conditions.
What is Experiment
200
Contains DNA, or the genetic material, of the cell.
What is a Nucleus
200
Organelles in plants and algal cells where photosynthesis takes place.
What is Chloroplast
200
Coiled structure made of DNA and proteins containing sister chromatids that is the form the genetic material of a cell goes through cell division.
What is Chromosome
200
The passing of characteristics from parents to offspring.
What is Heredity
300
A way of gaining knowledge about the natural world by asking questions and using evidence and logic to find the answers.
What is Science
300
The diffusion of water molecules across a membrane.
What is Osmosis
300
An energy-rich molecule produced in the light reactions and used up in the Calvin cycle to drive sugar synthesis.
What is ATP
300
Region of sister chromatids where they are joined together.
What is Centromere
300
Mendel’s first law of inheritance. The law states that there are two factors controlling a given characteristic in which one dominates the other. These factors separate during reproduction and go to different gametes, or a mature reproductive cell that eventually unites with another gamete to reproduce.
What is the Law of Segregation
400
A broad explanation of why something happens in nature that is widely accepted as true because it is supported by a great deal of evidence.
What is Scientific Theory
400
Process of maintaining a stable environment inside a cell or an entire organism.
What is Homeostasis
400
An electron carrier that transfers some of the energy absorbed from the sun in the light reactions to the Calvin cycle for sugar synthesis.
What is NADPH
400
Process where haploid cells become gametes.
What is Gametogenesis
400
Short fragments of DNA that comprise the lagging strand.
What is Okazaki Fragments
500
Variable in a scientific experiment that is manipulated to investigate its affect on another variable (the dependent variable).
What is Independent Variable
500
Type of vesicle transport that moves a substance out of the cell. A vesicle containing the substance moves through the cytoplasm to the cell membrane. Then, the vesicle membrane fuses with the cell membrane, and the substance is released outside the cell.
What is Exocytosis
500
Another way autotrophs make food. In this case, the autotrophic organisms use chemical energy instead of light energy. Chemoautotrophs typically harness the energy from the oxidation of inorganic molecules, such as hydrogen sulfide, to produce organic compounds from inorganic carbon ones.
What is Chemosynthesis
500
When cells divide in meiosis, each individual chromosome is separated randomly and independently.
What is Independent Assortment
500
Regulatory element in the promoter of most cells.
