Why would it be impossible to extract dna from cooked foods?

1 answer:

7 0

DNA is bound together by covalent bonds between different molecules. It also contains proteins, which again are held together in their specific structures by covalent bonds.

Covalent bonds may be broken when high temperatures are applied. The temperatures that a food encounters during the cooking cause the DNA to be denatured, meaning it cannot be extracted. The same occurs with other proteins such as enzymes and antibodies.

REY [17]

Answer:

Explanation:

Group of answer choices DNA sequences that are deduced by comparing many related DNA sequences are called CONSENSUS. Unlike DNA synthesis, RNA synthesis requires TRANSCRIPTION. PROMOTERS direct RNA polymerase to the initiation site. RNA synthesis complexes containing DNA, RNA, and polymerase perform TRANSLATION. RNA synthesis (tRNA, mRNA, and rRNA) takes place in complexes containing DNA, RNA, and polymerase are called TRANSCRIPTION BUBBLES. The expression of beta-galactosidase requires the induction of operons by addition of REPRESSORS.

Why does it make metabolic sense for the same hormone signal to stimulate glycogenolysis and inhibit glycolysis in the liver whi

Debora [2.8K]

This is because if the two metabolic processes were to be active at at the same time;

Two molecules of ATPs and Guanosine triphophate (sometimes used for energy transport) will be expended per each cycle, with no compensatory rate of replacements present at the moment in the cell,this affects cell metabolism for energy availability

2 Both Glycolysis and Gluconeogensis are both exergonic processes in cells. The heat energy liberated from these Calorinogenic effects will be higher than what the natural thermodynamic barrier of cells can withstand. Consequently; the heat will raise temperature of the cells affecting metabolic activities of hormones and enzymes which are (proteins) ,and easily denature by high temperatures.

However, in muscles cells,gluconeogeneis is a compensasory process of Glycolysis. This because during active exercise with high metabolic demand in muscles cells, glucose is rapidly metabolise to to pyruvate,(but not at the rate that the Citric acid cycle can metabolise) for Lactic acid production by muscles cells for energy production. Pyruvate must be broken down rapidly so that NAD+ will be available for Glycolysis to continue. Therefore to sustain Glycolysis at this rate continuous supply of glucose is supplied from Gluconeogenesis.

Nonrandom mating tends to _______ the frequencies of ______ genotypes. increase; homozygous decrease; homozygous increase; heter

Solnce55 [7]

The answer depends of the kind of non-randommating. If the non-random mating is the kind of positive assortative mating then it tends to increase the frequencies of homozygous genotypes. Positive assortative mating when individuals mate with other individuals like themselves. If the non-random mating is the kind of negative assortative mating, then the effect is the opposite as of the positive assortative mating, this is it tends to decrease the homozygous genotypes.

If sugar is sprinkled on a strawberry, osmosis will cause

Goshia [24]

Answer:

The correct answer is c. water to move out of the strawberry, making it smaller

Explanation:

Osmosis is the process refers to the movement of liquid molecule from the area of high solute concentration to an area of low solute concentration through a semipermeable membrane to equalize the osmotic balance.

Osmosis is important for any cell to maintain a proper osmotic balance of the cell. So if sugar is sprinkled on a strawberry the solute concentration outside the strawberry cells will increase which will result in water release from the cell.

This release of water from the cell will shrink the strawberry and make it small. Therefore the correct answer is c.
