The barcode gene used for discriminating between animals and algal species is the ________ gene.
Why is the coxL gene less useful in both in plants and fungi as a barcode gene?
A)Plants and fungi do not produce the product of the coxL gene.
B)The nucleotide sequence of this gene is too similar in plants and fungi.
C)The coxL gene exists in too many copies in plants and fungi.
D)Plants and fungi evolve too rapidly for the gene to be of any use.
E)None of the above are correct.
A barcode gene used for discriminating between plant species is the ________ gene.
Which of the following is a disadvantage to using DNA from organelles o obtain barcode genes?
A)Organelle DNA occurs in multiple copies.
B)Organelle DNA is more difficult to sequence.
C)No organelles have DNA.
D)Organelles are inherited only maternally;thus paternal DNA cannot be considered.
E)Organelle DNA evolves too slowly for differences to be detected.
