basic building blocks of protein molecules
a simple compound whose molecules can join together to form polymers
large compound formed from combinations of many monomers
building block (monomer) of nucleic acid polymers
a long chain of smaller molecules called nucleotides
site of photosynthesis
control center of the cell
Golgi Body Apparatus

a thin membrane around the cytoplasm of a cell
Powerhouse of the cell, organelle that is the site of ATP (energy) production
trait that will show up in an organism's phenotype if gene is present
trait that will only appear in the phenotype if organism inherits two of them; covered up by the dominant gene
one of two alternate forms of a gene that can have the same locus on homologous chromosomes and are responsible for alternative traits
When neither of the traits can show as one. (Red flower with a white center)
blending together of two alleles

change to a chromosome in which a fragment of the chromosome is removed
Change to a chromosome in which more is added to a fragment of the chromosome
change to a chromosome in which part of the chromosome is repeated
change to a chromosome in which a fragment of one chromosome attaches to a nonhomologous chromosome
The physical traits that appear in an individual as a result of its gentic make up.
genetic makeup of an organism
having identical alleles at corresponding chromosomal loci
having two different alleles for a trait
ability of an organism to control which genes are transcribed in response to the environment
(genetics) a segment of DNA that is involved in producing a polypeptide chain
a threadlike body in the cell nucleus that carries the genes in a linear order
(genetics) the organic process whereby the DNA sequence in a gene is copied into mRNA
decoding of a mRNA message into a polypeptide chain
(genetics) cell division that produces reproductive cells in sexually reproducing organisms
cell division in which the nucleus divides into nuclei containing the same number of chromosomes
(biology) an organism that has characteristics resulting from chromosomal alteration
protein that acts as a biological catalyst
organism whose cells contain nuclei
