Cards

Term
DNA (Deoxyribosenucleic acid)
Definition
a molecule that is the genetic basis of life.
Term
Gene
Definition
The pieces of DNA molecule that code for specific proteins.
Term
RNA (Ribonucleic acid)
Definition
A molecule used to translate the code from the DNA molecule out if the nucleus and to the ribosome to finally make a protein.
Term
Anticodon (tRNA)
Definition
A three-part nucleotide segmant that is the exact complement if ine mRNA codon
Term
Protein Synthesis (Transciption & Translation)
Definition
The process of making genes into proteins.
Term
Polymerase
Definition
An enzyme that picks up unattached nucleotide bases and matches then to their complementary bases on the DNA template strand.
Term
Guanine (G)
Definition
One of the four bases used in both DNA and RNA for pairing. Always binds with C
Term
Nucleotide
Definition
The building blocks of nucleic acids.
3 things Phosphate groups, sugar, Nitrogenous base.
Term
Deoxyribose
Definition
Sugar in the DNA
Term
Stop Codon
Definition
Three nucleotide segment that stops the translation process (UAA, UAG, UGA)
Term
Amino Acid
Definition
Building blocks of polypeptide chains (which form proteins)
Term
Translation
Definition
The second step in protein synthesis where mRNA is decoded and a polypeptide is formed
Term
Transfer RNA (tRNA)
Definition
anticodon--brings the amino acid to the ribosome to form a protein
Term
Enzyme
Definition
a protein that acts as a biochemical catalyst
Term
Thymine (T)
Definition
IN DNA ONLY---the base that binds with A
Term
Start Codon
Definition
AUG-Tells the tRNA when to start reading the mRNA strand
Term
Nitrogenous Bases
Definition
DNA: A-T C-G
RNA: A-U C-G
Term
Ribosome
Definition
the organelle that synthesis proteins
Made of rRNA
Term
Adenine (A)
Definition
Base that binds with T in DNA and U in RNA
Term
Cytosine (C)
Definition
Binds with G in both DNA and RNA
Term
Uracil (U)
Definition
Used In RNA only
Binds with A
Term
Ribose
Definition
sugar in RNA
Term
Transcription
Definition
the first step in protein synthesis, in which mRNA copies the DNA to be able to leave the nucleus
Term
Messenger RNA (mRNA)
Definition
copied from the DNA in the nucleus, so the information can leave the nucleus and go to the ribosome
Term
Ribosomal RNA (rRNA)
Definition
Type of RNA that makes up the ribosome
Term
Codon
Definition
three nucletides of mRNA that code for a amino acid
Term
Complmentary Pairs
Definition
DNA: A-T C-G
RNA: A-U C-G
