Answer:
True
Explanation:
DNA ligases are enzymes required for replication, repair, and recombination of DNA molecules. The DNA ligase repairs the break in the DNA molecule by the formation of a phosphodiester bond.
The bacterial genome consists of a circular DNA molecule, thereby laboratories use these enzymes to create recombinant DNA molecules
A membrana plasmática é basicamente uma borda entre o interior de uma célula e seu exterior. A membrana regula o que entra e sai da célula e é necessária para a sobrevivência da célula. sem ele, todo o conteúdo da célula se espalharia. Isso seria ruim. Cada célula tem uma membrana, assim como as organelas dentro da célula.
Answer:
Heyya!
Human development is a slow and gradual process. There seems to be slow and gradual change that becomes abrupt change. The mind has many connections and works according to past habits. A person who seeks to improve themselves will gradually change specific areas within their life. After a while there is a cascade effect that causes linked areas to be altered. Skills and methods that required practice and habit forming transition to being a natural part of life. When the personality suddenly changes, I use the term evolution. Whenever one occurs, the person will probably see their past self as problematic.
The Griffith's experiment, the Avery-MacLeod-McCarty experiment, and the Hershey–Chase experiments were the set of experiments that established DNA as the key hereditary molecule. The Avery-MacLeod-McCarty experiment was an extension to the Griffith's experiment. The heat killed virulent S strain cells of the Griffith's experiment were lysed to form a supernatant containing a mix of RNA, DNA, proteins and lipids from the cell. The supernatent was equally divided into 3 parts after the removal of the lipids. The 3 parts were respectively treated with an RNAase to degrade the RNA, DNAase to degrade the DNA and proteinase to degrade the proteins. The treated supernatant was then added into the culture containing the non-virulent R cells. In case of the supernatant treated with the DNAse, no transformation of R cells into S cells occurred. The transformation of R cells to S cells occurred in the proteinase and the RNAse cases. This indicated that DNA was the hereditary molecule and not protein or RNA.
