F215 Flash Cards

?
Genome
Entire DNA sequence of an organism
1 of 5
Characteristics of genetic code
Triplet code. Degenerate code (amino acids have more than one code). Some codes indicate 'stop'.
2 of 5
Transcription
Gene unwinds and unzips. Hydrogen bonds break. RNA binds onto the TEMPLATE STRAND. 2 extra phosphyl groups released for energy. mRNA exact copy of base sequence of CODING STRAND. Passes through nuclear pore to ribosome.
3 of 5
tRNA structure
Lengths of DNA folded into hairpin shapes. 3 unpaired bases at one end where a.acid joins. Anticodon, which binds to complementary codon on mRNA.
4 of 5
Translation
mRNA binds to ribosons
