Question 1 of 5
1. Question
Consider the following statements regarding Distributed ledger technology (DLT).
- Distributed ledger technology (DLT) is a digital system for recording the transaction of assets in which the details are recorded in multiple places at the same time.
- Unlike traditional databases, distributed ledgers have a central data store or administration functionality.
- Blockchain technology is a specific kind of Distributed ledger technology.
Which of the above statements is/are correct?
Correct
Solution: b)
Distributed ledger technology (DLT) and Block Chain technology:
- Distributed ledger technology (DLT) is a digital system for recording the transaction of assets in which the transactions and their details are recorded in multiple places at the same time.
- Unlike traditional databases, distributed ledgers have no central data store or administration functionality.
- Blockchain technology is a specific kind of DLT that came to prominence after Bitcoin, a cryptocurrency that used it, became popular.
Cryptocurrencies such as Bitcoin use codes to encrypt transactions and stack them up in blocks, creating Blockchains. It is the use of codes that differentiates cryptocurrencies from other virtual currencies.

Question 2 of 5
2. Question
Acinetobacter baumannii, Enterococcus faecalis, Escherichia coli are
Correct
Solution: c)
Some of the pathogens to look out for are Acinetobacter baumannii, Enterococcus faecalis, Escherichia coli, Salmonella typhi, Streptococcus pneumoniae and many more. These pathogens are commonly implicated as causative agents of healthcare associated infections because of their ability to develop resistance to antibiotics.

Question 4 of 5
4. Question
Consider the following statements regarding Bio-enzymes.
- Bio-enzymes are organic solutions produced through fermentation of organic waste like fruits, vegetable peels and flowers by mixing in sugar, jaggery/molasses and water.
- Yeast can be used to slow down the process of fermentation.
Which of the above statements is/are incorrect?
Correct
Solution: b)
Bio-enzymes are organic solutions produced through fermentation of organic waste including various fruits, vegetable peels and flowers, by mixing in sugar, jaggery/molasses and water. It takes 60-100 days to ferment organic waste. To fasten the fermentation, yeast can be used as culture to prepare it in 45-50 days.

Question 5 of 5
5. Question
Consider the following statements regarding Proteins.
- Proteins need to take a precise three-dimensional shape to become functional entities.
- Misfolding of proteins can cause a number of diseases like Parkinson’s disease and cataract.
- Most of the time, protein folding happens automatically.
Which of the above statements is/are correct?
Correct
Solution: a)
DNA is a linear chain of nucleotides, portions of which are faithfully transcribed into linear messenger RNA. The message in this RNA is translated into strings of amino acids – proteins. Proteins need to take a precise three-dimensional shape to become functional entities. This protein folding does not happen all by itself, at least most of the time. A special bunch of proteins called molecular chaperones assist in correctly folding the protein.
Misfolding of proteins can cause a number of diseases. Alpha-synuclein protein, present in neurons, is wrongly folded in Parkinson’s disease.
Aberrant folding of crystallins of the eye lens leads to cataract. In the eye lens, an abundant subset of proteins called alpha-crystallins themselves serve as chaperones.
