Restriction endonucleases are enzymes used in: ((MCAER 2014))

✅Explanation: Chromosome 1 is the largest human chromosome and contains the most DNA. It is estimated to be approximately 250 million base pairs long.

🔑Key Points:
-DNA is the genetic material that carries information to generations 
-It is made of Adenine, Guanine, Cytosine and Thiamine
-Human DNA contains about 3 billion base pairs
-Chromosomes contain DNA
-A chromosome is a long DNA molecule with part or all of the genetic material of an organism.
-Twenty-two [22] of these pairs -> Autosomes
-23rd pair [1] pair -> Sex chromosomes
-Females -> XX chromosome
-Males -> XY chromosome

🛑Additional Information:
-Ribosomes – Aid in protein synthesis
-Nucleus – Regulates the activities of cell and carries genetic information
-Chromosome – Carries DNA and transfer the genetic information to next generation
-Mitochondira – Power house of the cell
