A sequence of bases on DNA is unique for a person and information regarding this is called DNA fingerprinting. DNA fingerprinting can not be used for Correct Answer determine physical features

Concept:

  • DNA fingerprinting, also called DNA typing, DNA profiling, genetic fingerprinting, genotyping, or identity testing, in genetics.
  • It is a method of isolating and identifying variable elements within the base-pair sequence of DNA (deoxyribonucleic acid).
  • DNA fingerprint is a pattern of bands arising due to a specific arrangement of nucleotides in a person.
  • Such a pattern is unique to every person as the nucleotide arrangement/sequence is unique to that person, just like a fingerprint. 
  • So, different sequences of nucleotides pertaining to different people will give different DNA fingerprints. 
  • A sequence of bases on DNA is unique for a person and information regarding this is known as DNA fingerprinting.
  • Since such arrangements in the DNA of close relatives have many similarities.
  • It becomes possible to find out the hereditary relations using DNA fingerprinting.
  • The same principle is used to identify real parents in case of a parental dispute. 
  • DNA profiles are very useful in forensics.
  • DNA fingerprinting can also be used to identify the racial origin.
  • It is because only a tiny sample of human material left behind after a crime may be sufficient to identify someone. 
  • DNA fingerprinting only does not provide any information regarding physical identity.

Thus, DNA fingerprinting can not be used to determine physical features.

Important Points

  • DNA fingerprinting cannot be used to determine physical features.
  • Most physical features are not dependent on the genetic make-up of a person, except in the case of certain traits.

 Additional Information

  • The technique was developed in 1984 by British geneticist Alec Jeffreys.
  • Jeffreys recognized that each individual has a unique pattern of minisatellites.
  • The only exceptions are multiple individuals from a single zygote, such as identical twins.

There are flowers in a basket which are to be distributed to five persons standing in a row. The second person received half of the number of flowers given to the first person, the third person received half of the number of flowers received to the second person; the fourth person received half of the number of flowers received to the third person and the fifth person received half of the number of flowers received to the fourth person.

The question given below consists of a statement, followed by three arguments I, II and III. You have to decide which of the arguments is/are ‘strong’ arguments is/are ‘weak’ arguments and accordingly choose your answer from the alternatives given below each question. Statement: Chat bots and other interfaces are saving employees and HR heads time for more productive activities by providing information and replies to diverse queries or concerns. A few years ago, business communication was driven by multiple faxes in a day and emails were the only quick mode of exchanging information. This information went through the organisation's who's who, while the others were mostly engaged in the daily rut of redundant activities, preventing them from directing their capabilities towards more productive areas. Which of the following arguments brig out the idea that introduction of chat bots and other interfaces is not helping in boosting up the processes? Arguments: I. Using these conversational interfaces, HR departments are successfully aligning themselves with the swiftly-changing organisational processes. These platforms represent people friendly technologies that keep employee experience at the centre, continuously evolving with them.  II. HR technologies are increasingly using advanced machine learning for measuring and analysing workforce engagement. Sentiment analysis is a unique way of gauging an employee's disposition towards the organisation, providing valuable insights essential for improving productivity and predicting attrition rates.  III. The seamless experience chat bots provide makes employees focus on activities that require critical abilities and strategic thinking. Besides enabling HR processes such as generating leave applications and reimbursement forms, the use of chatbots provides quick and smooth access to data from anywhere, anytime. 
Consider the following statements regarding Genome Sequencing: 1. Genome sequencing is figuring out the order of DNA nucleotides, or bases, in a genome—the order of Adenine, Cytosine, Guanines, and Thymine that make up an organism's DNA. 2. Human genome is made up of 46 chromosome pairs with a total of about 3 billion DNA base pairs. 3. There are 24 distinct human chromosomes: 22 autosomal chromosomes, plus the sex-determining X and Y chromosomes. Which of the statements given above is/are correct?
Each of the question below consists of a question and three statements number I, II and III given below it. You have to decide whether the data provided in the statement are sufficient to answer the question. Two person X and Y together can make 25% of total number of bricks in 4.8 days. Another person Z can make 50 bricks in a day. What is the time taken by person X and Z together to make the total number of bricks? I. Dimensions of a brick is (3cm × 4cm × 5cm) while the dimension of a cuboids when all the bricks are put together is (72cm × 80cm × 50cm) and ratio of number of days taken by X and Y alone to make the total number of bricks is 3 : 2. II. The total number of bricks is 4800 and person Y can make 150 bricks in day. III. Total volume of all the bricks together is 1.008m3 and dimension of a bricks is (5cm × 6cm × 7cm) and time taken by Z to make total number of bricks is 200 % more than the total time taken by person Y to make total number of bricks.
