A sequence of DNA is altered. Explain how this change to the sequence of DNA could result in a bioschemical reaction no longer o

Zina [86]

Answer:

DNA codes for enzymes (proteins or RNA). And every reaction is controlled by any enzyme.

So, a change in the DNA can result into formation of some non-functional enzyme or a less efficient enzyme or some other protein.

As there's no enzyme for the particular reaction, the reaction wouldn't occur.

Primary structure- It shows the sequence of amino acids in any protein. No role in the functional part of enzyme. 2D structure.

Tertiary structure- It is coiling of enzyme upon itself to form the active or cataytic site. Plays role in catabolic or anabolic function of the enzyme. 3D structure.

Amino acid- As the name goes by, it means a molecule having an amino group (NH2) and an acid group (COOH). Basic building molecules of the proteins.

Active site- The structure formed by the coiling of enzyme (found in tertiary and quaternary structure). This is where the substrate binds to the enzyme

Substrate- This is the molecule which binds to the enzyme and is converted into product by the enzyme.

Enzyme- This is the proteinaceous(sometimes RNA) molecule which accelerates the metabolic functions of our body.

mRNA- This is the molecule formed the DNA present in the nucleus of the cell after transcription. The mRNA carried the information from the DNA present in the cell to form the protein molecule. The basic structural component of this molecule is ribonucleotide molecules.

Vaselesa [24]

As I watched, the sun broke weakly through, brightened the rich red of the fawns, and kindled their white spots.” E.B. White, “Twins” Poems and Sketches Analysis: What kind of flames does kindled imply? How does this verb suit the purpose of the sentence? Kindled is the start of a gentle flame so in the sentence it applies that on the rich red of the fawn's coat, the white spots kindle a soft fire. The verb suits the purpose of the sentence because it’s purpose is to catch the fawns in the early morning. The gleam of the the fawns patches and correlates the fire to the budding deer. Kindled implies a friendly flame. The sentence expresses the fauns white glow. Would the sentence be strengthened or weakened by changing the
