The expected frequencies are f(A1) = 0.9700, f(A2) = 0.0300
according to the Hardy-Weinberg model. For biologists studying a large flatworm
population in the lab, which Hardy-Weinberg condition is most difficult to meet
there is no mutation. It is called a genetic disorder in homozygous recessives
that causes death during the teenage years.
Proteins.
Protein synthesis (process includes transcription and translation):
The DNA sequence is copied (transcribed) by mRNA in the nucleus then translated in ribosomes which will instruct tRNA to collect specific amino acids to bring back to the ribosome by reading 3 letters at once (called codon, and one codon codes for 1 amino acid). Those amino acids will attach to each other and when the sequence codes for stop, it stops, and a protein forms.
