Which one of the following best distinguishes PCR from RT-PCR?

Automatic Identification System (AIS) is primarily intended to:

Which property is particularly important in explaining why nanoparticles can exhibit behaviour different from the corresponding bulk material?

A researcher wants to introduce a precise sequence change using CRISPR-Cas9. Which of the following is most relevant to obtaining a targeted change rather than relying solely on error-prone repair?

Consider the following statements about India's LWE response:

1. 1.Security Related Expenditure can support operational and security needs in affected areas.
2. 2.Special Central Assistance has been used to address critical infrastructure and service gaps in most affected districts.
3. 3.Civic Action Programmes seek to improve interaction between security forces and local communities.
4. 4.The Union approach treats development and governance as irrelevant to the security problem.

Which of the statements given above are correct?

Which one of the following pairs is correctly matched?

Consider the following statements about India's Prototype Fast Breeder Reactor (PFBR):

1. 1.It uses mixed-oxide fuel containing uranium and plutonium.
2. 2.Fast neutrons are used to convert fertile uranium-238 into fissile plutonium-239 in the breeding process.
3. 3.Thorium-232 is itself fissile and directly sustains the primary fission chain reaction in the PFBR.

A CRISPR-Cas9 experiment produces an unintended edit at a site resembling the intended target. Which concept most directly describes this problem?

Consider the following statements:

1. 1.A semiconductor fabrication facility manufactures devices on wafers through repeated process steps such as deposition, lithography and etching.
2. 2.OSAT facilities focus on assembly and testing after wafer fabrication.
3. 3.A chip-design incentive is equivalent to fiscal support for building a wafer fabrication plant.

Which of the statements given above are correct?

Consider the following pairs:

1. 1.Hypersonic glide vehicle — unpowered or predominantly gliding manoeuvre after a boost phase
2. 2.Scramjet — air-breathing propulsion in which combustion occurs with supersonic airflow through the engine
3. 3.Ballistic missile — necessarily remains below Mach 5 throughout its flight
4. 4.Thermal protection — manages extreme aerodynamic heating encountered at high speed
