Answer:
is the evolution of mean fitness an answer
Explanation:
The correct order from smallest to largest
would be:<span>
<span>H < C < N < O < Amino acid < Globular
Structure < Amino acid sequence</span>
<span>The smallest should begin from the basic elements. Among C,
H, O and N, the lightest is Hydrogen, followed by Carbon, Nitrogen, and Oxygen.
Next is the amino acid which is the most basic unit of protein. This is the
linear structure. Followed by the globular structure which is the tertiary
structure. The whole would be the amino acid sequence which is quaternary
structure.</span></span>
Answer:
The correct answer is option A) "The plasmid would not contain the human gene because the cuts are not compatible".
Explanation:
One of the basis of genetic engineering is to use the proper restriction enzymes to cut fragments of DNA. After cutting DNA with restriction enzymes most of the time the fragments have sticky ends, which are a few nucleotides that are one stranded and complementary to each other. Scientists take advantage of this characteristic and use the same restriction enzyme to cut genes and plasmid and later put it together with DNA ligases. If genes and plasmids are accidentally cut with different restriction enzyme it is very likely that the plasmid would not contain the human gene because the cuts are not compatible, since no sticky ends are generated.
There are approximately 25,000 genes contained on the 46 chromosomes in each cell of the human body. This means that one chromosome contains thousands of genes. A person can have normal chromosomes in number and structure, but still have a disease or condition caused by a mutation in one or more of the genes on the chromosomes. A single gene defect usually does not cause the chromosome structure or number to be abnormal. Similarly, a person can have normal genes; however, if the person has extra copies of genes due to a chromosome abnormality, then those extra copies can cause the genes to not work properly.
