Structure of a Functional Amyloid Protein Subunit Computed Using
Structure of a Functional Amyloid Protein Subunit Computed Using

... In contrast to disease-related amyloids caused by protein misfolding, functional amyloids are ‘beneficial’ aggregation systems that are evolved by nature and evolutionarily conserved across species.2 This suggests that there is an evolutionary pressure to maintain the amyloid structure of these prote ...

They constitute all proteinaceous material of the cell including the cytoskeleton and the protein component of enzymes, receptors, and signaling molecules. In addition, amino acids are used for the growth and maintenance of cells. Cell culture m ...

... Europe at the time of Mendel’s work was at the R locus (Bhattacharyya et al. 1990). This character also appears to be the first for which a detailed anatomical and physiological explanation was sought. As early as 1903 (Gregory 1903), it became clear that round and wrinkled seeds differed in the quan ...

By using these methods, at least 12 families of retrotransposons of rice (Tosl-Tosl2) were isolated. One retrotransposon, Tos3-1, was subjected to detailed investigation. Tos3-1 is 5.2 kb long and ha ...

Point mutation



A point mutation, or single base modification, is a type of mutation that causes a single nucleotide base change, insertion, or deletion of the genetic material, DNA or RNA. The term frameshift mutation indicates the addition or deletion of a base pair. A point mutant is an individual that is affected by a point mutation.Repeat induced point mutations are recurring point mutations, discussed below.
