Answer:
In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length which can be radioactively or fluorescently labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide substances that are complementary to the sequence in the probe.DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labelled, for example with radioisotopes, epitopes, biotin or fluorophores to enable their detection.

En biología molecular, una sonda de hibridación es un fragmento de ADN o ARN de longitud variable que puede marcarse de forma radiactiva o fluorescente. Luego puede usarse en muestras de ADN o ARN para detectar la presencia de sustancias nucleotídicas que son complementarias a la secuencia en la sonda. Las sondas de ADN son tramos de ADN monocatenario utilizados para detectar la presencia de secuencias complementarias de ácido nucleico (secuencias diana) por hibridación Las sondas de ADN generalmente están marcadas, por ejemplo, con radioisótopos, epítopos, biotina o fluoróforos para permitir su detección.
Explanation:
If a cell has been exposed to cyanide, most of the cyanide’s
contents will likely be found in the mitochondria. The mitochondria is
responsible of for providing power generator the cell as a way of having an ATP
that powers the cell.
Considering the following;
I. Heat is not readily available to all living cells.
II. Heat at excessive amounts denatures proteins.
III. Heat does not provide the activation energy for their reactions.
IV. When a critical temperature is reached, proteins no longer function
Answer;
I and IV
Explanation;
Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.
Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
Answer:
Explanation:
Gert Kema, a professor of tropical plant pathology at Wageningen University and a banana expert, led the study. "Black sigatoka has significant social, environmental and economic implications around the world. Thanks to the DNA sequencing of Pseudocercospora, we gain deeper insight into the interaction between the fungus and banana plants. It can provide us with clues to increase the sustainability of banana cultivation and make it better for the environment, the locals, and the economy. For example, the findings show production and It provides us with the opportunity to develop banana plants that are suitable for export and resistant to black sigatoka. ”
This new understanding of the DNA of black sigatoka also provides new information for more effective development. increase. And hopefully a crop protection product that is less harmful to the environment. This can reduce the amount of spray and improve the quality of life for those who work in plantations and those who live nearby.
