Biomolecular programs
Hey,
Just wondering if anyone could point me in the direction of some cool freeware biomolecular programs which would aid in learning biochemistry, just something to doodle around with and explore concepts.

Re: Re:
If speciation is to occur, they must have varying evolutionary advantages that increase the frequency of certain genotypes, even in sympatric isolation, some sort of isolation must be there to create at least two distinct species. The next question is how to define when there are new species, morph...

Steven, you are right that dominant alleles mask recessive ones in normal expression, but with genomic imprinting because it is parental specific it ignores or masks the other. For example if you had a dominant allele 'A' from the mother and recessive allele 'a' from the father and genomic imprintin...

Re: Gene Rearrangement and Evolution
The overall DNA content does not change, although with "jumping genes" (Transposons) mutations can occur and change the DNA. Whether or not changing the sequence of genes in DNA is classed as changing the DNA would depend on the functionality of the sequence. Since I am not 100% sure wheth...

A species is an evolutionarily independent population or group of populations These populations can be categorized generally in three ways: Biological: Reproductive isolation between populations, this includes prezygotic and postzygotic isolation. Morphospecies: Morphologically distinct populations ...
