Question

multiple select question select all that apply select all the reasons why mitochondrial dna (mtdna) might be better to use than nuclear dna in studying molecular evolution. many copies mtdna are present in cells mtdna doesnt accumulate mutations mtdna contains more genes than nuclear dna mtdna may be more likely to remain intact in extinct organisms

Explanation:

mtDNA has multiple copies per cell, fewer genes than nuclear DNA, and can remain intact in extinct organisms, making it useful for molecular evolution studies.

Answer:

• Many copies mtDNA are present in cells
• mtDNA contains more genes than nuclear DNA
• mtDNA may be more likely to remain intact in extinct organisms
