Comparing Characteristics Flashcards
Why can and can’t observable characteristic be used to compare
Our phenotype is based on our genes as our genes code for protein which in turn determine how we look like
However our first genotype can also be influenced by environmental factors so it is hard to tell whether it’s environmental or genti
How can we compare the genetic code
We can used technology to compare the dna code as we can tag different bases with different colours the laser can then scan the nucleotide and produce a band of colours animals that are more similar will have aimmilqir bands and due to mutations there will be more and more differences in the colours of the two strands
Why can we use amino acid sequence to compare base sequence
As amino acids are specific to codon the the sequence of amino acids can be helped to determine the similarity of genes
