codon optimization is a technique molecular biologists sometimes use to maximize the over-expression of a protein by making use of the most frequently-occurring aminoacylated trnas in an artificially- synthesized gene. what fundamental property of the genetic code allows this technique to work?
Codon-optimization describes gene engineering tactics that use synonymous codon adjustments to boom protein production.
Applications for codon-optimization encompass recombinant protein capsules and nucleic acid therapies, along with gene therapy, mRNA therapy, and DNA/RNA vaccines.
This technique is viable due to the fact degeneracy of the genetic code permits maximum amino acids to be encoded through multiple synonymous codon and due to the fact codon utilization could have a stated impact on tiers of protein expression. Indeed, codon optimization has been suggested to boom protein expression through > 1000-fold. This is viable due to the fact maximum amino acids are encoded through multiple codon.

carbon dioxide entering the ocean from the atmosphere continually.explain how some og this carbon can become “tied up” in the ocean for hundreds and sometimes millions of years
Answer:
Carbon can become "tied up" in the ocean for hundreds and sometimes millions of years because dissolved carbon dioxide in water can sink with cold water to the bottom where it is moved slowly by deep ocean currents for hundreds of years before it is released to the atmosphere. This can lead to ocean acidification (the ongoing decrease (more acidic) in the pH of the Earth's oceans, caused by the uptake of carbon dioxide from the atmosphere)

During the process of diffusion, solute particles will generally move from an area of high solute concentration, to an area of low solute concentration. This happens because the random motion of particles suspended in a fluid results in their uniform distribution .
Diffusion happens due to the kinetic energy that causes a random motion of molecules. When a molecule collides with another molecule or the wall of the container it is in, the kinetic energy of the molecule is transferred to the molecules it collides with, causing them to move in different directions.
Diffusion can occur in a variety of mediums, including gases, liquids, and solids. It plays a significant role in various biological processes. For example, it helps transport nutrients and oxygen to cells and allows for the excretion of waste products. Diffusion is a passive process that does not require energy.

Your scan of Lucy's ADA gene showed a mutation in the active site. The normal sequence for codon #243 is GAC, however Lucy's codon #243 was mutated to be GAU. What type of mutation is this and why was it not a problem for Lucy?
Silent mutations are point mutation that replace a base by another one, but the affected codon codifies for the same amino acid as the original one, not altering the protein's function. The mutation in the exposed example is a silent mutation. The mutated and the original codons code for the amino acid aspartic acid, (ASP) and lead to the same protein, which is why it not a problem for Lucy.
What is a silent mutation?
When a change occurs in a codon affecting a single base pair, it is known as a point mutation.
Points mutations might be either silent, missense, or nonsense.
In silent mutations, the resulting mRNA codon codes for the same amino acid as the unmutated sequence. This means that, even when a base replacement has occurred, the affected codon still codes for the same amino acid, and the protein is synthesized as usual (with no modifications).
In the exposed example,
Original codon GACMutated codon GAUThis is silent mutation in which the mutated and original codons code for the same amino acid: ASP.
