Scientists worked backwards by looking into the amino acid sequence to determine the DNA base. They started with the mRNA which transcribes the codon into respective amino acids. This human gene is found on top of chromosome 11 in human DNA.
Hope this helps!
Answer:
According to the case history, Mrs.Wharton is a 59-year-old woman who presented in the dermatologist's office with a complaint of changes in a mole or a<u> nevus.</u>
Explanation:
The correct answer to complete the sentence is the term "nevus". A nevus (plural:nevi) is the medical term for the word mole, which in most occasions is what patients will use to describe the condition. A nevus or mole are the product of a collection of colored cells, and are very common among people, with the average of 10 to 40 nevi per person. Although most nevus are harmless in their nature, it is important for everyone that has one to check them regularly, and in the case that the person sees a change in the appearance of the nevus he/she should go to the doctor's office for a medical examination, just like Mrs. Wharton did.

Answer:
The cell cycle has two main phases, interphase and mitosis. Mitosis is the process during which one cell divides into two. Interphase is the time during which preparations for mitosis are made
Explanation:
The molecules move from a region of higher water potential to a region of lower water potential, through a semi permeable membrane.
Osmosis can be seen as water molecules moving down a water potential gradient. Water potential is the tendency of water molecules movement. The higher the water concentration is, the higher the water potential. This net movement of osmosis will continue until equilibrium is achieved, which is, when the water potential of both sides of the membrane is the same. At that time, water molecules still move, but theres no net movement, that is for example the number of molecules moving from left to right is the same number of molecules moving from right to left.
Osmosis is a natural event, as long as there's a semi permeable membrane, and a water potential gradient. This process doesn't require extra energy. Osmosis is only the movement of water molecules, other substances move by diffusion down the concentration gradient.
