DNA Double stranded Complimentary Composed of Nucleotides
DNA replication DNA Helicase – breaks hydrogen bonds holding complimentary strands together Forms replication fork Leading strand Lagging strand
DNA Replication DNA is read 5’ to 3’
Leading Stand Helicase -> RNA pimase -> DNA polymerase
Lagging Stands Helicase -> RNA primase -> DNA polymerase -> okazaki fragments -> DNA polymerase cleans up RNA primase strand -> DNA ligase

Protein Synthesis 2 parts Transcription To copy segment of DNA Translation To translate the language of nitrogenous bases into amino acids
RNA vs. DNA Difference between mRNA and DNA Single stranded vs. Double stranded The sugar has an extra oxygen, ribose vs. deoxyribose Uses uricil “U” instead of thymine
Transcription Production of mRNA RNA primase binds to DNA at a promoter region RNA polymerase adds bases copying the gene

Packaged mRNA is processed to leave the nucleus Extras are cut out Splicosomes Introns Exons Poly-A tail 5’ cap
Translation mRNA has left the nucleus. Binds with ribosome mRNA -> tRNA -> amino acids -> folded proteins What’s the Problem? mRNA UGGCUUGCAUGCCGGAGUCCACGUAAUCA Into Amino acids A U C G Amino Acids
Translation tRNA consists of a Anticodon – 3 bases that match codon Amino acid Codon – 3 base sequence on mRNA
Translation mRNA -> tRNA -> amino acids -> proteins

RNA Synthesis or Transcription Used in the process of protein synthesis!
Gene Protein Chapter 17. Protein Synthesis / Gene Expression Gene expression: The translation of information encoded in a gene into protein or RNA. Expressed.
Cell Structure Review and Introduction to DNA. Did you know? 100 years ago we did not know why some children had brown eyes and some blue 75 years.
The Central Dogma of Genetics. The Central Dogma Proposed by Francis Crick in 1959 DNA codes for RNA RNA codes for protein Protein determines our physical.
11.1 Genes are made of DNA. Griffith Experiment Avery Experiment -Destroyed proteins -Mice still died with mix.
Protein Synthesis. Codes! DNA contains codes –Codons 3 nucleotide bases = amino acid –Sequence of amino acids = proteins –DNA copied = mRNA (messenger.
