Comparing amino acid primary sequences is advantageous for determining evolutionary relatedness, as more similar amino acids indicate a closer relationship; however, the disadvantage is that important proteins may show little variation due to less selective pressure.
A comparação da sequência primária de aminoácidos é vantajosa para determinar o parentesco evolutivo, pois mais aminoácidos semelhantes indicam uma relação mais próxima; no entanto, a desvantagem é que proteínas importantes podem ter pouca variação devido à menor pressão seletiva.
| Front | What is the method of protein(amino acid) sequence and what are its pros and cons |
|---|---|
| Back | Method: compare primary structures and count how many amino acids are the same PROS: The more amino acids the same the closer related CONS: May not be much difference in amino acid sequence in important proteins because of less selective pressure on amino acid sequence which don't function |
