Students have asked these similar questions
DNA is responsible for your phenotype, but to what extent? How much, if at all, do environmental factors play a role? Can you find examples (remember keep your sources academic)?
First there was the RNA world, and now we have a DNA world. Why would natural selection favor the transition to a DNA-based world?
Even though they have several differences, a bacterium and a human cell will both contain DNA. With respect to evolution, what does this fact suggest?

These base-pair changes account for the physical differences seen between the two species. One difference between the two species is the shape of their hands and feet. Figure 1 compares the hand and a foot of a chimpanzee and a gorilla. Much like a human hand, chimpanzee and gorilla hands have opposable thumbs. This adaptation is good for picking up small objects and eating with one hand. Chimpanzees have fingers that are much longer and narrower than gorillas' fingers and have thumbs that are slightly smaller and sit farther down on their palms than gorillas' thumbs do.

- Evolution happens over time through mutations at the chromosomal and nucleotide levels. Mutations can be beneficial, neutral, or harmful. Most mutations are neutral. Describe 6 different types of mutations that can occur at the chromosomal and nucleotide levels. Make sure to include 3 types of each.arrow_forwardAstronomers have made great strides in sending probes out to other planets and moons in our solar system.

- DNA sequences can act as "tape measures of evolution". Scientists analyzing the human genome sequence were surprised to find that some regions of the human genome that are most highly conserved (similar to comparable regions in other species) don't code for proteins at all.
