the first stage of protein synthesis, the process of copying a segment of
DNA into RNA

an allele that is hidden whenever the dominant allele is present;
requires two copies of the allele to be expressed

the process by which organisms that are better adapted to their
environment are most likely to survive and reproduce

an organism that has an internal backbone

the thing observed and measured in an experiment

the community of organisms (the biotic factors) AND the nonliving
environment (the abiotic factors) that interact in a particular area

the genetic makeup of an organism

the formation of new and distinct species (through evolution)

an organism that does not have an internal backbone

all the things that must remain constant or unchanging in the
experiment

the second stage of protein synthesis; a ribosome ‘reads’ a strand of mRNA
and synthesizes a protein made of amino acids

Incomplete dominance

any difference between individuals of the same species

a chemical that carries messages to affect growth and development

the shape of a DNA molecule, two strands that twist around each other
like a twisted ladder

The study of how organisms interact with each other and with the ecosystem

Fossil

Any relationship in which two species live closely together and at least one of
the species benefits

Extra

a disease where some body cells grow and divide uncontrollably (usually due to
mutation and error in mitosis)

a type of RNA in the cytoplasm that carries an amino acid to the
ribosome during protein synthesis

the behaviors or physical characters that allow organisms to live successfully
in their environment

a well tested explanation for a wide range of observations or
experimental results
