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.

I'm pretty sure nobody would have that information at hand. Only an estimate. Perhaps try to look at geographical information of ant population areas and their changes, that might give you a closer idea.

Develop a theory.
Test the theory.
Verify the theory.

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...

Helicase is part of the protein complex that replicates DNA. DNA replication begins by a "bubble" forming in the molecule where the first few hydrogen bonds between complementary base pairs are broken opening the DNA molecule for replication. From here Helicase works in both directions ope...

It has been done, google it.

Isn't that in Napoleon Dynamite? lol stupid movie.

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...

Your females are heterozygous for 3 recessive alleles, so they will have the genotype: AaBbCc aabbcc is homozygous recessive AABBCC is homozygous dominant AaBBCc is a mix, heterozygous for Aa and Cc alleles, homozygous for B. When you say your males are "normal" does this imply they are AA...

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...

For number 2: pneumomediastinum Ruptured bronchus or alveoli in the lungs from excessive pressure. May be caused by holding breath while ascending. lung expansion injury It can be caused by holding breath while ascending. Basically if you hold your breath and then ascend the air inside you lungs exp...

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 ...
