|
translation occurs in
|
cytoplasm at ribosomes
|
|
|
what does translation do?
|
makes proteins
mRNA pairs wiht RNA that has specific AA attached 3 base condon of mRNA pairs with 3 base anti-codon of tRNA |
|
|
mutation caused by:
|
UV, gamma (most powerful), x-rays, toxic chemicals, spontaneous changes due to heat
|
|
|
3 types of mutations
|
1.substition (only affects one codon)
2.insertions (changes all after) 3.deletion |
