What are the three types of point mutations?
Silent, missense, nonsense
200
the new codon encodes a different amino acid and there is a change in the amino acid sequence.
missense mutation

When paired chromosomes fair to separate during meiosis
300
How many amino acids are read at a time during translation and what are they called?
Three at a time
Codons
300
This type of RNA carries amino acids to the ribosome during translation
tRNA
400
This type of mutation changes the entire reading frame downstream of the mutation
Frameshift

What is a silent mutation?
Point mutation where the amino acid is the same at the end
400
What amino acid does the codon AUG code for?
Met (Start)
