Germline theory
WebThe alternative template theory, which I’ll explain later in this essay, implied that the amino acid sequences of an antibody’s polypeptides (thus the nucleotide sequences of the corresponding mRNAs) did not suffice to explain its antigen specificity. Plants and basal metazoans such as sponges (Porifera) and corals (Anthozoa) do not sequester a distinct germline, generating gametes from multipotent stem cell lineages that also give rise to ordinary somatic tissues. It is therefore likely that germline sequestration first evolved in complex animals with sophisticated body plans, i.e. bilaterians. There are several theories on the origin of the strict germline-soma distinction. Setting aside an isolated germ cell population early in embr…

WebJan 11, 2024 · Which theory explains huge antibody diversity? There are two major theories on the origin of antibody diversity: the germline theory and the somatic diversification theory. According to the germline theory, each individual antibody variable region structure is encoded in a separate germline gene.

WebThe germ-line theory was a proposed explanation for immunoglobulin diversity that proposed that each antibody was encoded in a separate germline gene. This does not occur in most species (including humans), but may occur in Elasmobranchs.
WebHuman germline engineering is the process by which the genome of an individual is edited in such a way that the change is heritable.
