Study Notes
- The following notes contribute to 20% of the final grade
- Topic covers DNA, RNA, and Protein
Transcription
- This is the process where RNA is synthesized using DNA as a template
Translation
- This is the process where mRNA directs the synthesis of a protein
RNA
- A nucleic acid composed of ribose, phosphate, and one of four nitrogenous bases
- The nitrogenous bases are adenine, cytosine, guanine, or uracil
mRNA
- It consists of long strands of RNA
- It is complementary to one strand of DNA
tRNA
- Small RNA molecules that transport amino acids to the ribosome
rRNA
- RNA molecules make up part of the ribosome
Codon
- A codon is a group of three nitrogenous bases in DNA or mRNA
- Codes for one amino acid
Anticodon
- A three-base coding sequence that is complementary to a codon on the mRNA
Introns
- Intervening DNA sequences that are transcribed
- Introns are then removed from the final DNA
Exons
- Protein coding sequences in DNA are transcribed into mRNA
- Exons are translated into protein
RNA Polymerase
- This enzyme catalyzes the synthesis of mRNA
- Uses a specific section of DNA as a template
