Only with the appearance of true humans – the genusHomo– did hominins begin to look and behave a little more like we do. Few now doubt that our genus evolved from a species of australopith, although exactly which one is a matter of debate. It was probably Lucy’s speciesAustralopithecus...
DNA ___ is the process of using DNA as a blueprint to make a copy of the DNA. How are DNA, genes, and cell division connected? How did the instructions contained in DNA evolve? Describe how DNA replication is initiated, including how the DNA is made accessible for replication, and ...
How did DNA repair evolve? How does DNA repair relate to type 1 diabetes? Explain the importance and process of DNA proofreading and repair. What is CRISPR? Describe the steps of how it is used by researchers to repair or alter the DNA of any organism. ...
This process frequently involves duplication of an existing gene, and a subsequent divergence of one of the duplicated copies from the ancestral sequence1,2,3. Several studies have shown that protein coding genes can also emerge de novo, in DNA sequences that did not previously encode a protein...

Question 3: Where Did the First Living Cell Come From? The Future of Evolution The Basic Process of Evolution The basic theory of evolution is surprisingly simple. It has three essential parts: It is possible for the DNA of an organism to occasionally change, or mutate. A mutation changes...
This paper uses a variety of time-series methods and a new real wage series from [Clark, G., 2005. The condition of the working class in England, 1209 to 2004. Journal of Political Economy 113, 520 1307–1340.] to re-examine economic-demographic interactions in pre-industrial England. We...

Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....
Through natural selection, random mutations accumulate in any virus. This process is sped up inRNAviruses, including SARS-CoV-2. If and when a set of mutations provides a survival advantage to a variant over its predecessors, the variant will out-compete all other e...
