The answer is mutation. A mutation is the alteration of a nucleotide sequence in DNA, changed DNA sequence is transcribed into RNA. this changed RNA sequence in translated into misinformed protein. (you might want to try looking for the answer instead of wasting points making a question that exists already)

Cell biologists studying the mobility of plasma membrane proteins fused mouse and human cells together, creating a heterokaryon.

m_a_m_a [10]

Answer: Fluorescence microscopy

Explanation:

A protein is substance that is the essential constituent of living cells because it forms part of its structure. They are also found in plasma membrane, where they assist substances to cross the membrane. Proteins can be:

Integral: permanently attached within the plasma membrane.
Transmembrane: it spans the entirety of the cell membrane.
Peripheral: are only temporarily associated to the membrane.

Some integral proteins can act as cellular receptors. Other proteins are responsible for cell adhesion (binding of a cell to another cell or to a surface). On the outside of the cell membranes, attached to other proteins, are the carbohydrate chains that act as labels identifying the type of cell.

A heterokaryon is a multinucleate cell and in this experiment the scientists fuse a human cell and a mouse cell, each of them will have their own proteins. At first, the human and mouse proteins where found in separated halves of this heterokaryon. But after a while, those proteins where mixed and could no longer be identified.

A fluorescent chemical called a fluorophore is able to be absorb light of specific wavelengths and then emit light of longer wavelengths. The proteins can be modified and marked with different colored fluorophores to detect them, even if they are mixed in the heterokaryon. Then, they can be seen with a Fluorescence microscopy, to identify them through different colors.

For the following questions, please fill in the blank with the correct number of chromosomes (e.g. 4). Please do not spell out t

andrezito [222]

Answer:

Double number of chromosome.

Explanation:

There are 16 chromosomes in G2 phase of the cell cycle because in G2 phase, the replication of DNA occurs which doubles the number of chromosome. It is a gap phase present between replication of DNA and mitosis so it contains 16 number of chromosomes in the cell. After mitosis, the chromosomes number distributed equally among daughter cells.
