Indian Space Research Organisation Research Scientist Interview Questions and Answers

The last propulsion system I built was a hybrid rocket engine for a small satellite.

• Developed a hybrid rocket engine using a combination of solid fuel and liquid oxidizer

• Tested the engine for efficiency and performance

• Integrated the propulsion system into a small satellite for orbital maneuvers

CSS stands for Cascading Style Sheets. Time complexity of merge sort is O(n log n) and binary search is O(log n).

• CSS stands for Cascading Style Sheets and is used for styling web pages.

• Time complexity of merge sort is O(n log n) where n is the number of elements in the array.

• Time complexity of binary search is O(log n) where n is the number of elements in the array.

Merge sort has a time complexity of O(n log n) and binary search has a time complexity of O(log n).

• Merge sort has a time complexity of O(n log n) because it divides the array into halves and merges them back together.

• Binary search has a time complexity of O(log n) because it halves the search space in each iteration.

• Example: For an array of size n, merge sort takes O(n log n) time to sort the array and binary search ta

Different cloning methods include restriction enzyme cloning, PCR cloning, and Gibson assembly.

• Restriction enzyme cloning involves cutting DNA with restriction enzymes and ligating it into a vector.

• PCR cloning amplifies DNA fragments using polymerase chain reaction and inserts them into a vector.

• Gibson assembly is a method that joins DNA fragments with overlapping ends using a mix of DNA polymerase, exonuclease, and li
