The answer is D.) all cell are composed of a membrane...
Answer:
WILD TYPE: NMNGK
CODON SEQUENCE: AAU AUG AAU GGC AAA
MUTANT: NMIWQCVMKD
Explanation:
CODON SEQUENCE – AAU AUG AUA UGG CAA AUA UGU GUA AUG AAA GAU
in the mutant insertion of U nucleotide shifted the frame. if the U (underlined and bold) was not inserted then the wild-type sequence will be
NMNGKYV (STOP CODON) = 269 AMINO ACID LONG WILD TYPE PROTEIN.
CODON SEQUENCE AAU AUG AAU GGC AAA UAU GUG UAA
Answer and explanation:
If a cell has a higher concentration of sodium inside than the sodium concentration that there is outside of it, there will be a chemical gradient that will direct the sodium to the outside, to equate the concentrations between the inside of the cell and the outside of the cell.
The membrane voltage on cells depends on the conductance of each ion. The more conductant an ion is, the more likely is that it will go through the membrane from the inside to the outside or vice versa. This conductivity relies on the number of active protein channels specific to that ion that can be found in the membrane. If the membrane voltage is negative when the cell is at resting potential, it means that the most conductant ion is one whose equilibrium potential is negative as well. Sodium's equilibrium potential is positive, which suggests that there is another ion inside this cell that is more conductant and whose equilibrium potential is negative - probably potassium.
Given that the membrane voltage is negative, which means that there are more positively charged particles outside than inside, the sodium will most likely flow from the outside to the inside - the electrical force on sodium will be from the outside to the inside.
The determining direction of the sodium will be given by the electrochemical gradient and will depend on the magnitude of the chemical gradient and the electrical one.
We will attempt to introduce a gene responsible for the resistance to the antibiotic ampicillin.
Bacterial transformation is a molecular technique widely used in genetic engineering. Its basis involves the introduction of a foreign DNA into a host organism. This will result in the expression of a foreign gene by the host bacterium. In this example, our host organism is a bacterium who is sensitive to the antibiotic ampicillin. By introducing a gene for resistance to this antibiotic, the bacterium will become ampicillin resistant.
<span>There are several instance today of how science can be used to make decisions. One very good example is forensic determination of a baby paternity. In a situation where there is controversy over the paternity of a child, DNA analysis can be used to determine the true father of a child.</span><span />
