Summary Introduction
Concept introduction: The DNA found in the mitochondrial region of eukaryotic cell is called as mitochondrial DNA. mitochondria are semi-autonomous, containing their own genome, and it gears the replication, protein synthesis., and transcription process of a cell.

. DNA sequences in many human genes are very similar to thesequences of corresponding genes in chimpanzees. The mostlikely explanation for this result is that(A) humans and chimpanzees share a relatively recent common ancestor.(B) humans evolved from chimpanzees.(C) chimpanzees evolved from humans.(D) convergent evolution led to the DNA similarities.
Why are human and chimpanzee DNA 96 percent similar? Please choose the best option.a) Both groups show similarities in their fossil record.b) Humans and chimpanzees share several similar traits such as the use of tools.c) These two species descended from a recent common ancestor.d) Natural selection has favored those particular genes in both humans and chimpanzees.
The Neanderthal nuclear genome:
A. Shows that Neanderthals inherited their ability to flake stone directly from Homo habilis.
B. Is overwhelmingly similar to the modern human genome.
C. Demonstrates once and for all that Neanderthals had language.
D. Is composed exclusively of mitochondrial DNA.
E. Indicates that most Neanderthal females died young, which explains why Neanderthal populations were so small.
