18. RNAi is a technique that silences genes by targeting them and degrading their mRNA. How can this technique be used in scient

ific laboratories?
A. RNAi is observed in nature, but it can't be used in laboratories.
B. RNAi allows scientists to turn off one gene specifically to study its effect.
C. RNAi has been used in laboratories to make bacteria more susceptible to antibiotics, but has limited application in eukaryotic cells.
D. RNAi is a powerful tool for degrading mRNA, but because it doesn't degrade other types of RNA, its use is limited.

Answer:

B

Explanation:

RNAi is a cellular mechanism for post-transcriptional gene silencing. After transcription of a gene into mRNA, small interfering RNA (siRNA) and microRNA (miRNA) can target the mRNA to form dsRNA. This mRNA then becomes a target of ribonucleases such as the Dicer that break it apart. These mRNA, therefore, do not reach the cytoplasm for translation by ribosomes. This mechanism is hence harnessed and manipulated by scientists to study genes by silencing them.

Como estan compuestos los sistemas de coordinacion, control e integracion
Nonamiya [84]

This book describes how control of distributed systems can be advanced by an integration of control, communication, and computation. The global control objectives are met by judicious combinations of local and nonlocal observations taking advantage of various forms of communication exchanges between distributed controllers. Control architectures are considered according to increasing degrees of cooperation of local controllers: fully distributed or decentralized control, control with communication between controllers, coordination control, and multilevel control. The book covers also topics bridging computer science, communication, and control, like communication for control of networks, average consensus for distributed systems, and modeling and verification of discrete and of hybrid systems.

Examples and case studies are introduced in the first part of the text and developed throughout the book. They include:

<span>control of underwater vehicles,automated-guided vehicles on a container terminal,control of a printer as a complex machine, andcontrol of an electric power system.</span>

The book is composed of short essays each within eight pages, including suggestions and references for further research and reading.

By reading the essays collected in the book Coordination Control of Distributed Systems, graduate students and post-docs will be introduced to the research frontiers in control of decentralized and of distributed systems. Control theorists and practitioners with backgrounds in electrical, mechanical, civil and aerospace engineering will find in the book information and inspiration to transfer to their fields of interest the state-of-art in coordination control.

List the quality control measures taken to ensure contamination does not occur during the Chelex extraction process (DNA extract
Gwar [14]

Answer and Explanation:

To promote a good DNA extraction through the Chelex extraction protocol, it is important to follow some measures, which are essential for the entire process to take place efficiently.

The most important measure is to avoid contamination. In this case, all surfaces, container and substances used must be properly sterilized, preventing unnecessary elements from coming into contact with the DNA sample or the protocol reagents.

It is important that the researcher is wearing clean, appropriate clothing and gloves when using this protocol. This avoids impurities and contamination with the researcher's DNA.

Another precaution must be taken with the DNA sample and the reagents that will be used during the extraction. All must be stored correctly, preventing their degradation, especially the DNA, which is a very unstable molecule.

Finally, the researcher must strictly follow all the steps of the protocol as indicated.

Answer:

Convection

Explanation:

Definition

convection- the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat.
