1. Week 6 Vocab Definitions

2. Nucleotide
The monomer of all nucleic acids. Made of a sugar, a phosphate group, and a nitrogen base.
DNA Replication
Creating identical copies of DNA from DNA. Occurs in the nucleus during S-phase of Interphase.
Transcription
Using DNA to produce mRNA. Occurs in the nucleus

3. Translation
Process of matching mRNA codons to tRNA anticodons to assemble amino acids and form proteins. Occurs at the Ribosome.
M RNA
carries the genetic message from the nucleus to the ribosome for protein synthesis
T RNA
transfers a specific amino acid to a growing polypeptide chain at the ribosome during translation

4. Codon
A set of three nucleotide bases of mRNA that code for a specific amino acid.
Anti codon
Three tRNA nucleotides that correspond to the three bases of the codon on the mRNA.

5. Mutation
changes to the base pair sequence of the genetic material of an organism
Karyotype
A visual representation of chromosomes of an organism. Shows gender and/or nondisjunction.
