Important Questions on Patterns in the Structure of DNA
Choose the enzyme that is involved in the continuous replication of DNA strand.
Curling of tendrils is due to
What is the error in above diagram?
Restriction endonucleases are used as:
Which of the following enzymes separates the two strands of DNA during replication?
Which of the following bonds is present between nitrogen bases of DNA?
Name of chemical bond present between nitrogen bases of DNA?
Two functions of primary DNA replicating enzyme DNA pol III (holoenzyme) in bacteria are
The double helix and the twisted-ladder structure of deoxyribonucleic acid was discovered by
Discontinuous synthesis of DNA occurs in one strand because DNA dependent DNA polymerase catalyses polymerisation only in 3'5' direction.
DNA is a polymer of nucleotides which are linked to each other by 3' - 5' phosphodiester bonds. To prevent polymerisation of nucleotides, which of the following modification (s) would you choose?
The fact that a purine base always pairs through hydrogen bonds with a pyrimidine base in the DNA double helix leads to uniform width throughout DNA.
The bond that links two nucleotides together in a DNA strand is called the glycosidic bond.
The proof for semiconservative replication of DNA through experiment was first shown in a
Okazaki fragments formed during DNA replication are used to elongate
What do you think about the base sequence of two strands of DNA segment?
5' - GAATTC - 3'
3' - CTTAAG - 5'
DNA replication is a discontinuous process.
Meselson and Stahl used isotopes of which element?
