Human Gamete Compatibility Going Backwards

... on homology, however, may or may not be relevant. Theoretically, haploid genome should be sufficient to produce an organism as it contains full complement of genes. However, because some critical genes can be recessive, two copies are required. This leads to the requirement for the homologous ...

Living or not? (viruses,viroids and prions).

... make some inferences about the viruses' evolutionary history. And what they find supports the view that the virus started out with a much larger complement of genes. For example, Mimivirus has a suite of genes that can help repair DNA. Megavirus has those plus one other that is specialized for ...

DNA helix and gene

Yes and no, they do not. They are complementary to each other, so one gene sequence can be found on one strand and the second gene sequence on another (read in the opposite direction). However, both strands are required for transcription to ...

Re: mutations and dependencies

... function of bashing or breaking stuff. Many things meet the requirements for being considered blunt objects, thus the requirements are loose. As a complement to loose requirements, there are also functions with specific requirements. A given thing is less likely to meet the requirements for a function ...
