Genes, DNA, RNA

DNA Deoxyribonucleic Acid

Ribonucleic Acid (RNA)

The Genetic Code

DNA Replication (Semi-Conservative Replication)

Transcription: DNA to mRNA

[EXAM] Total number of bases in the DNA sense strand and total number of bases in the mRNA are different

Translation: mRNA to Protein via tRNA

Requirement for Translation

Carries the code from the DNA that will be translated into an amino acid sequence

Transfer amino acids to their correct position on mRNA strand

Provide the environment for tRNA attachment and amino acid linkage

DNA and Inheritance

Gene Mutations

Cystic Fibrosis - Defective Gene

Phenylketonuria (PKU) - Defective Gene
