DNA Technology, Classification and Diversity 4B Flashcards
How can genome sequencing help clarify evolutionary relationship
The entire base sequence of an organisms DNA can be determined which can then be compared with another organism’s DNA to see how closely related they are
How can comparing amino acid sequences help clarify evolutionary relationship
The sequence of amino acids in a protein is coded for by the base sequence in DNA. Related organisms have similar DNA sequences, so similar amino acid sequences . The more similar the amino acid sequence the more closely related the organism
How immunological comparisons help clarify evolutionary relationship
Similar proteins will also bind to the same antibodies
How do new technologies change the way that genetic diversity is assessed
Early estimates made by measuring the frequency of a measurable or observable characteristic
Since different alleles determine different characteristics a high number of different characteristics means a high genetic diversity
