How does DNA account for both the common features and diversity observed in living organisms and how can it help us understand the evolutionary relationships between them?
Homework Answers
DNA being the genetic material in an organism when compared with other organism it is found to be approximately 99% similar only 1% shows diversity. This 1% diversity represents the tandem repeats in the coding sequence.
The DNA sequence can also help us to understand the evolutionary relationships between organism like the chimpanzee we share 90% of our DNA with them and evolved from them.

The group of organisms humans belong to is relatively small. All living organisms share a common ancestor, as evidenced by the commonality of DNA and ribosomes. Humans are not a unique form of life. Our ability to learn about the natural world does provide us an advantage over many species, especially if we use this advantage wisely. Antibiotics are prevalent in bacteria and fungi, whereas other drugs are derived from plants. Humans are not the most common species on Earth....

A) Explain how geography, mass extinctions and adaptive radiation help explain the diversity of living organisms. B) Explain how changes in development can explain the evolution of new live forms. .Using the information you presented about geography, mass extinction, adaptive radiation and embryonic development, from the previous two questions, explain how living organisms evolve.

Ecology is the study of the relationships between living organisms, including humans, and their physical environment; it seeks to understand the vital connections between plants and animals and the world around them. Ecology also provides information about the benefits of ecosystems and how we can use Earth’s resources in ways that leave the environment healthy for future generations.(Ecological Society of America Website) Q1. Recent fires have devastated large parts of California. What are some ecological interactions that may have contributed...

Mitochondrial DNA (mtDNA) is exclusively inherited from the mother. Because of its unique inheritance pattern, how can it be helpful to genetic researchers? A. It helps scientists better understand genetic conditions such as male pattern baldness and colorblindness. B. It provides insight into sex-linked traits that are passed through the X chromosome. C. It allows scientists to trace maternal lineages back many generations and show evolutionary relationships. D. It opens the possibility of asexual reproduction in organisms that previously reproduced...

Firstly I could do with a brief description of mitochondrial DNA. How does the structure of DNA in mitochondria compare to animal DNA (for the sake of simplicity let's say human - some animals might have unusual DNA structure) and what living organism is the mitochondrial genome most akin to? (Circular like bacteria maybe?) and are the mitochondria within a single human homogenous? Secondly, and most importantly to my aim, does the mitochondrial genome recombine in anyway? Is the process...
