Which of these accurately describes the process of translation?

1 answer:

3 0

The correct answer is A) a single amino acid may have more than one codon that translates for it.
This property of the codon is called codon degeneracy and is the redundancy of the genetic code. As a result, there is the multiplicity of three-base-pair codon combinations that specify an amino acid and that increases tolerance to point mutations (synonymous mutations). Usually, the codons encoding one amino acid differ in the second or third position.

oksano4ka [1.4K]

Answer:

Golgi body aka Golgi apparatus

Explanation:

The golgi body processes and packages macromolecules (proteins, lipids). It processes simple molecules and combines then to produce more complex ones.

The organelle can then package those molecules in vesicles to be transported around the cell or it can store them.

It also produces lysosomes (contains digestive enzymes that break down old or worn out cells).

1. The cells in our bodies are surrounded by these types of solutions.

Ksenya-84 [330]

Answer:

1. The cells in our bodies are surrounded by these types of solutions. → Isotonic solution.

3. When an animal cell is places in this solution, it will burst (get layer) → Hypotonic solution.

4. When an animal cell is placed in this solution, it will shrivel or shrink (get smaller) → Hypertonic solution.

5. This is a solution with more solute than the cell. Hypertonic solution.

Explanation:

The cells in the body are in a balance of substances —concentration of solutes— between their cytoplasm and the extracellular space. This balance is dynamic in living beings, due to the constant exchange of ions and substances between the intracellular and extracellular space. For this reason, the extracellular medium is isotonic with the cytoplasm.

A cell can lose or gain water depending on the amount of solutes that a medium has in which it is found, with respect to the cytoplasm. This difference in solutes concentrations produces an osmotic gradient that drags water from the least concentrated solution to the most concentrated, through the process of osmosis, which seeks to achieve an equilibrium of concentrations.

When a animal cell is exposed to a hypertonic solution —with a higher concentration of solutes— it loses water and tends to dehydrate and become smaller.
An animal cell in a hypotonic solution receives water, so it can expand and even burst.

In practice, the concentrations of intracellular and extracellular solutes depend not only on the osmotic gradient, but also on the concentration gradient of substances.

k0ka [10]

The given question is incomplete, the complete question is:

Elizabeth is conducting an investigation to study how molecules are transported into and out of a cell. Elizabeth builds a model of a cell using a U-shaped tube. A barrier, which is permeable to water, but not sugar, is placed on the bottom of the tube to model the cell membrane. Elizabeth adds two different solutions to each side of the tube. The solute in each solution is sugar and the solvent is water. The initial levels of solution in Side A and Side B are equal. The concentration of sugar in Side A is lower than the concentration of sugar in Side B.

What is Elizabeth likely to observe?

A. Water molecules will move from Side A to Side B. The solution level on Side A will fall and the solution level on Side B will rise.

B. Water molecules will move from Side B to Side A. The solution level on Side A will rise and the solution level on Side B will fall.

C. Sugar molecules will move from Side A to Side B. The solution level on Side A will fall and the solution level on Side B will rise.

D. Sugar molecules will move from Side B to Side A. The solution level on Side A will rise and the solution level on Side B will fall.

Answer:

The correct answer is statement B, that is, the molecules of water will move from side A to side B. The level of solution on the side A will fall and the level of solution on the side will elevate.

Explanation:

Based on the given information, it is clear that the barrier is only permeable to water, thus, movement of water will take place through osmosis down the gradient, that is, from lower to the region of higher solute concentration. The water seems to equalize the concentrations of solute present on side A with the concentrations of solute present on side B.

Osmosis refers to a phenomenon in which the molecules of solvent seem to pass via a semipermeable membrane from the area of less concentration to the area of higher concentration, therefore, equating the concentrations on both sides of the membrane.
