WebJan 8, 2013 · Germline determination is believed to occur by either preformation or epigenesis. Animals that undergo germ cell specification by preformation have a continuous germline. However, animals with germline determination by epigenesis have a discontinuous germline, with somatic cells intercalated. 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… WebSep 30, 2024 · Once specified, germ cells would develop further in an autonomous manner. A. Weismann was the first to propose a model for cell specification. His views implied that later in the development as well as during the lifetime of an organism, changes that occurred in the somatic cells would never be passed on to the germ cells.
