Duchenne muyscular dystrophy is caused by a mutation on the X chromosome, so a male gets it from his mother's X, if she is a carrier. The male child gets a Y and no X from his father, so the disease is always transmitted through the X from the mother. If a female gets Duchenne muscular dystrophy she has to have two X chromosomes, one from a carrier mother and another from from an affected father. This is virtually impossible because most males die before childbearing age and there is no way a female child can get an X from a man who does not live long enough to procreate. About eight percent of carrier women do show some muscle weakness, but they do not have the disease.
Answer:
The team would have to replace the nucleus.
Explanation:
Prokaryotic cells, such as the Mycoplasma capricolum cell used in the experiment do not contain either membrane bound organelles or a defined nucleus. Prokaryotic DNA floats around freely in the cytoplasm in a region called the nucleoid.
The genetic material of eukaryotic cells is protected by a membrane bound nucleus. Therefore, in order to replace an animal cell's DNA, the whole nucleus has to be removed.
Example:
In the process of cloning, the oocyte (egg cell) that receives the nucleus (from somatic cell) of the desired species or individual has to be enucleated i.e. its own nucleus has to be removed. This process is called somatic cell nuclear transfer.

Answer:
This is a picture of an aminoacid chain
Explanation:
In an amino acid chain all amino acids ( for example GLY, VAL, or ARG) are linked by peptide bonds. Long chains, also called polymers, of amino acids are called proteins. The enlarged photo is an example of a structure of an amino acid. They have an amine (-NH2) and carboxyl (-COOH) functional group, along with a side chain (R group), specific to each amino acid.
