Q
Q: What is the significance of the 'sticky ends' in recombinant DNA technology?
Solution:
'Sticky ends' are overhanging sequences that allow for the easy ligation of DNA fragments during recombinant DNA technology.
Steps: 5
Show Steps
Step 1: Understand that DNA is made up of sequences of nucleotides.
Step 2: Learn that when DNA is cut by certain enzymes, it can create 'sticky ends' which are short, single-stranded overhangs.
Step 3: Recognize that these sticky ends can easily pair with complementary sequences of DNA.
Step 4: Realize that this pairing allows for the joining of different DNA fragments, which is essential in recombinant DNA technology.
Step 5: Conclude that 'sticky ends' make it easier to insert new genes into DNA, helping scientists create modified organisms.
