40 million years
If you compare the sequences of both the organisms, then you can see that both of them differ at 5 nucleotide positions. It means 5 nucleotide changes have occured in 40 million years. So, 5 more changes will also occur in another 40 million years so, that total changes become 10 base pairs.
Please rate.

Humans and Chimps share a 9,826 nucleotides out of 10,000 in
sequences. Therefore, the Human and Chimp nucleotide difference out
of 10,000 is 174. Gorillas and my new species differ by only 165
nucleotides. A) K=(-3/4)In(1-(4(0.0174)/3))=0.0176050171.
L=K/2t=0.0176050171/2(6600000)=1.33x10^-9. B)
K=(-3/4)In(1-(4(0.0165)/3))=0.0166842067. t=K/2L=0.0166842067. That
is 6.2x10^6 years ago. By using the molecular clock method to
estimate the two species, we can say that the species most likely
diverged nearly 6 million years ago. C) I am uncertain what to
write here but I...

Case Study: As a member of a research team studying a tribe found in a remote region of New Guinea, you make the astonishing discovery that they have only two V genes for the L chain and three V genes for the H chain of immunoglobulins. Nevertheless, they seem healthy and able to resist the diversity of pathogenic organisms endemic to the area. Suggest how this might be accomplished 1. The DNA for an H chain in a B cell...

Genetics Worksheet Week 3: Gene Regulation and Epigenetics 1. Duchenne muscular dystrophy is caused by a mutation in a gene that is 2.5 million nucleotides in length and encodes a protein called dystrophin. The dystrophin protein itself is 3684 amino acids in length. Calculate below the approximate size of the mRNA that encodes dystrophin. Approximately what percentage of the gene that encodes dystrophin is intron sequence? The human genome encodes a much greater variety and number of proteins than the...

The following statements apply to concepts and material discussed in Chapter 15; identify which statement is TRUE. Answers: A common ancestor of two species on evolutionary trees can be found at the point where the two branches meet. Humans evolved from Neanderthals about 50,000 years ago. Mitochondrial DNA is not particularly useful when trying to determine the movement pattern of humans historically across the globe. Scientists can estimate when species diverged from a common ancestor by comparing their Karyotypes. We...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
