Answer:
Both new strands could be synthesized continuously like the leading strand
Explanation:
The DNA pol III is an enzyme that can add nucleotides to create the new DNA strand while reading one of the main strands of DNA from 3' to 5'. This new type of DNA pol III that can add nucleotides to either the 5' or the 3' end will make two continuous strands as when the DNA pol III reads the DNA from 3' to 5' and not one continuous and one discontinuous strand as when the normal DNA pol III reads the strand from 5' to 3'.
Didn't you say that the water at 39 degrees is more dense than water at its freezing point? I think the reason organisms would die is because the water already starting to structure in a crystal form, when it starts to freeze into ice. This probably why it kills the organisms, is because the water ceases to allow the organism to function at those temperatures.
Answer:
The viral genome is covered by a nucleocapsid protein called N. Two other proteins in the virus are the large protein called L, and the phosphoprotein called P. Both of these are involved with making new copies of the measles virus.
Explanation:
I got this from the wikipedia
Answer:
The capillary membranes that filter substances moving between the cerebral blood vessels and the brain are called the blood-brain barrier.
Explanation:
Capillaries are the smallest type of blood vessel in the body. Capillaries enable the exchange of substances between the blood and surrounding tissues. They are thinner than arteries and veins, because their walls are made up of only a single layer of endothelial cells, the flat cells that line all blood vessels. Capillaries function to deliver nutrients and oxygen to tissues and remove the byproducts of cellular reactions, such as water and carbon dioxide.
The Blood-brain barrier is an anatomic and biochemical barrier that protects the brain from potentially harmful substances. It is a highly selective membrane barrier at the brain microvessel level which aids transport between the systemic circulation and the central nervous system.
The Blood–brain barrier restricts the passage of pathogens, aids in ensuring solutes are diffused in the blood, and hydrophilic or large molecules into the cerebrospinal fluid, while allowing the diffusion of hydrophobic molecules (oxygen, carbondioxide, hormones) and small polar molecules.
