Lack of expression of XIST from a small ring X chromosome

... HhaI resulted in loss of only one allele, that from the active X chromosome (Figure 3B). The ZXDA gene in Xp11 contains a polymorphic CA repeat in the transcribed but untranslated region of the gene. This gene is subject to X-chromosome inactivation, so expression of only the allele on the active X ...

However, in eukaryotic cells (animals, plants, fungi, protists), the raw polypeptides are often much shorter than the genes that coded for them. In fact, whole sections of a gene may not be translated at all. Eukaryotic cells have mR ...

Therefore in strains with replication problems, ruvAB proteins (Holliday junction branch migration) lead to broken chromosomes, which is likely the mechanism of the lethali ...

Microevolution

Microevolution is the change in allele frequencies that occur over time within a population. This change is due to four different processes: mutation, selection (natural and artificial), gene flow, and genetic drift. This change happens over a relatively short (in evolutionary terms) amount of time compared to the changes termed 'macroevolution' which is where greater differences in the population occur.Population genetics is the branch of biology that provides the mathematical structure for the study of the process of microevolution. Ecological genetics concerns itself with observing microevolution in the wild. Typically, observable instances of evolution are examples of microevolution; for example, bacterial strains that have antibiotic resistance.Microevolution over time leads to speciation or the appearance of novel structure, sometimes classified as macroevolution. Macro and microevolution describe fundamentally identical processes on different scales.
