Unit 8: Protein Synthesis

Biology Standard- H.B-4: The student will demonstrate an understanding of the molecular basis of heredity.

Protein Synthesis Unit:

Key Concepts:

Part 1:

Nucleic Acids:

Deoxyribonucleic Acid (DNA) & Ribonucleic Acid (RNA)

Nucleotides: nitrogenous base, sugar, phosphate group

Complementary Bases

Base-Pairing Rules

DNA: A--T G---C

RNA: A--U G--C

Stuructural Shape:

DNA=double helix

RNA=single strand

Important People:

Rosalind Franklin-Photo 51

James Watson and Francis Crick-Nobel Prize for discovering the Double Helix structure

Part 2:

Central Dogma:

Replication-->occurs in Nucleus

UPCOMING EVENTS:

3-14: DNA Structure Mini-Quiz

3-15: DNA Extraction Lab

3-16, 3-17, & 3/20: Protein Synthesis Gizmo

3-21: 3D DNA Model Due (CP ONLY)

Transcription-->RNA is transcribed in Nucleus, then RNA leaves

Translation-->Takes place in the Cytoplasm

mRNA-->messenger RNA

rRNA-->ribosomal RNA

tRNA-->transfer RNA

3 codons-->code for 1 amino acid-->amino acids make up proteins

Other Vocab: helicase, DNA polymerase, and RNA polymerase, protein synthesis, codon, gene, chromosome, DNA, enzyme, codon site/anti-codon site, mutations, amino acid, protein, and polypeptide chain.
