This expertise, referred to as recombinant DNA technology, originated in the early 1970’s with the discovery of ., enzymes capable of specifically cleaving DNA into definable fragments. This chapter will describe this technology as well as more recent advances iPriapism 发表于 2025-3-25 17:37:18

Spezielle Argumente der juristischen Logik,All known enzymes are proteins. One exception to this statement might be the self-splicing of ribosomal RNA which does not involve any protein molecule. RNA serves as enzyme in this case.ITCH 发表于 2025-3-26 17:11:33
https://doi.org/10.1007/978-3-642-52931-3Amino acids are ingested in large amounts as structural components of dietary proteins. Unlike carbohydrate and fat, there are no large reserve stores of protein in the body. Thus, a continuous intake is required if tissue breakdown is to be avoided.
