Answer:
The third sentence is not correct. The correct statement would be as follows:
because the contents of the lumen of ER (or any other compartment) in the secretory or endocytic pathways never mix with the cytosol, Proteins that enter these pathways is never imported again.
Explanation:
During mitosis, specifically during prophase, when the nuclear envelope breaks down, or in other words, retracts from the chromatin, its content that is the membrane protein intermix with the ER membrane protein. However its content will always remain separated from that of the cytosol because of the presence of an intact membrane.
Answer and Explanation:
The manipulation of the gene is called genetic engineering. In genetic engineering, fragments of genes are cloned by leading the genes into the host cell. The advantage of using a prokaryotic host system in genetic engineering is that bacterial cells are used to produce commercially significant products. For example, human growth hormone helps to treat dwarfism, and human insulin production, which is used to treat diabetes. The bacterium P.putida is created by genetic engineering, which is used to break down petroleum products. Genetic engineering also carries some potential risks, such as transferring the selected gene into another speice, benefit one species can harm another speice. Therefore genetic engineering must be used in limit in prokaryotes. These limitations are also addressable in single-cell eukaryotic systems. Biologics-based therapeutic medicines such as a vaccine, gene therapies, and cell therapies known as bioproduction are produced. Medicines are so complex that they can only be formed in a living system. Biopharmaceuticals, value-added food, fuels, chemicals, antibiotics, and many other products are produced by bioproduction.

A scientist designed an experiment to test the effect of temperature on bacterial growth. The independent variable in this experiment was temperature.
<h3>What is the bacterial growth?</h3>
The outcomes display that microbes have a better increase price at 20, 25 and 30°C and 30°C than at 3°C. In general, an boom in temperature will boom enzyme pastime. But if temperatures get too excessive, enzyme pastime will reduce, and the protein (the enzyme) will denature.
General, the better the temperature, the greater without problems microorganisms can develop as much as a sure point. Very excessive and coffee temperatures each impede the enzyme strategies microorganisms rely on to survive.
