A segment of DNA on a chromosome that codes for a specific trait
Gene
the appearance in a phenotype of a characteristic attributed to a particular gene.
Expression
Describes a trait that covers over, or dominates, another form of that trait.
Dominant
The pyrimidines base that hydrogen bonds with Guanine in DNA
Cytosine
An allele that is masked when a dominant allele is present
Recessive
A purine base that hydrogen bonds with thymine in the DNA double helix
Adenine
The purine base that hydrogen bonds with Cytosine in DNA
Guanine
a pyrimidines base found in RNA (but not in DNA) that hydrogen bonds with Adenine
Uracil
The pyrimidines base that hydrogen bonds with the nucleotide adenine in DNA.
Thymine
mRNA, a RNA molecule that carries copies of instructions for the assembly of amino acids into proteins from DNA to the rest of the cell
Messenger RNA
type of RNA molecule that transfers amino acids to ribosomes during protein synthesis
Transfer RNA
Type of RNA that makes up the major part of ribosomes
Ribosomal RNA
monomer (Building block) of nucleic acids made up of a 5-carbon sugar, a phosphate group, and a nitrogenous base
Nucleotide
process whereby the DNA sequence in a gene is copied into mRNA
Transcription
Cytoplasmic organelles at which proteins are synthesized.
Ribosome
Process by which mRNA is decoded and a protein is produced
Translation
deoxyribonucleic acid, a self-replicating material present in nearly all living organisms as the main constituent of chromosomes. It is the carrier of genetic information.
DNA
A part of the cell containing DNA and RNA and responsible for growth and reproduction
Nucleus
Process by which a cell divides into two new daughter cells
Cell Division
part of eukaryotic cell division during which the cell nucleus divides creating two identical daughter cells
