1 Present in mammalian cells for degradation of DNA when a cell dies.
2 Used in genetic engineering for ligating two molecules
3 Synthesized by bacteria as a part of their defense mechanism
4 Used in invitro DNA synthesis
Explanation:
Restriction endonucleases are molecular scissors which are used to cleave the DNA segments in Recombinant DNA technology. They are used in Invitro DNA Synthesis. They are synthesized as a part of their defense.

Construction of recombinant DNA involves
1 Cleaving DNA segments with endonuclease and rejoining them with ligase
2 Cleaving and rejoining DNA segments with endonuclease alone
3 Cleaving and rejoining DNA segments with ligase alone
4 Cleaving DNA segments with ligase and rejoining them with endonuclease
Explanation:
Construction of Recombinant DNA involves cleaving of DNA segments with endonuclease and rejoining them with ligase.

Given below is a sample of portion of DNA strand giving the base sequence on the opposite strands. What is so special shown in it? 5' - GAATTC - 3' 3' - CTTAAG - 5'
1 Palindromic sequence of base pairs
2 Start codon at the 5' end
3 Deletion mutation
4 Replication completed
Explanation:
Palindromic sequence are sequence of base pairs that reads same on the two strands when orientation of reading is kept the same.

Choose the bacterium which is not a source of REN.
1 Haemophilus influenzae
2 Escherichia coli
3 Agrobacterium tumefaciens
4 Bacillus amyloliquefaciens
Explanation:
No restriction endonuclease is extracted from Agrobacterium tumefaciens. Rest three contain REN, Haemophilus influenzae has HindIII, Escherichia coli has EcoRI and Bacillus amyloliquefaciens has BamHI.
