(genetics) the organic process whereby the DNA sequence in a gene is copied into mRNA
(genetics) the process whereby genetic information coded in messenger RNA directs the formation of a specific protein at a ribosome in the cytoplasm
A three-nucleotide sequence of DNA or mRNA that specifies a particular amino acid or termination signal; the basic unit of the genetic code.
monomer that makes up proteins; contains carboxyl and amino functional groups
a class of nutrients that builds body tissues and supplies energy. protein is made of amino acids.

one allele is not completely dominant over the other allele
a condition in which both alleles for a gene are fully expressed
three or more alleles of the same gene
observed trait of an organism that masks the recessive form of a trait
The inherited characteristic often masked by the dominant characteristic and not seen in an organism.
genetic makeup of an organism
physical characteristics of an organism
having two identical alleles for a trait
having two different alleles for a trait
sex linked trait
