ddNTPs - Dideoxynucleotides and abbreviated as ddNTPs.

They are chain-elongating inhibitors of DNA polymerase, used in the Sanger method for DNA sequencing.

They have a hydrogen at the 3’ carbon of the ribose sugar.

The two most widely recognized tools used to influence a Nation's Economic activity are Monetary policy and Fiscal policy.

• Monetary policy is primarily concerned with the management of interest rates and the total supply of money in circulation and is generally carried out by central banks

• Fiscal policy is the collective term for the taxing and spending actions of governments.

Light amplification by stimulated emission of radiation.

The Indian Space Research Organisation (ISRO) has successfully launched its 3136 kg GSAT-19 communication satellite with its brand new and heaviest – Geosynchronous Satellite Launch Vehicle Mark-III D-1 (GSLV-Mk III D-1) satellite into Geosynchronous Transfer Orbit (GTO) from the Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh on June 5, 2017. The satellite GSAT-19 has an intended life span of 10 years and is developed to improve telecommunication and broadcasting areas. The GSLV-Mk III is popularly known as “fat boy” and is developed for 15 years at a cost of around Rs 300 crore. The rocket is capable of carrying payloads of up to 4,000 kg into the GTO and 10,000 kg into the Low Earth Orbit (LEO). The GSLV-Mk III is a three stage rocket. Its first stage is made of two strap on motors filled with solid fuel. The second stage uses the liquid fuel and the third is the cryogenic upper stage “C25”, which is powered by the highly complex indigenous cryogenic engine “CE20”. The number 20 denotes the 20-ton thrust it generates for the rocket to reach the intended height with the heavy mass on board.

While a test plan is being created, risks involved in testing the product are to be taken into consideration along with possibility of their occurrence and the damage they may cause along with solutions; if any. Detailed study of this is called as Risk Analysis.

Some of the risks could be:

New Hardware 

New Technology 

New Automation Tool 

Sequence of code delivery 

Availability of application test resources 

Identify and describe the risk magnitude indicators: High, Medium and Low

High magnitude means the effect of the risk would be very high and non-tolerable. Company may face severe loss and its reputation is at risk. Must be tested.

Medium: tolerable but not desirable. Company may suffer financially but there is limited liability or loss of reputation. Should be tested.

Low: tolerable. Little or no external exposure. Little or no financial loss. Company’s reputation unaffected. Might be tested.

Three perspectives of Risk Assessment: Effect, Cause and Likelihood.

To assess risk by Effect, identify a condition, event or action and try to determine its impact.

To asses risk by Cause is opposite of by Effect. Begin by stating an undesirable event or condition and identify the set of events that could have permitted the condition to exist.

To asses risk by Likelihood is to determine the probability that a requirement will not be satisfied.
