Final answer:
When calf liver DNA is digested with EcoRI, the EcoRI enzyme recognizes and cuts specific sequences in the DNA, generating single-stranded overhangs called sticky ends. These sticky ends can be used in molecular biology techniques like cloning.
Step-by-step explanation:
When the calf liver DNA is digested with EcoRI, the EcoRI enzyme recognizes and cuts the sequence GAATTC in the DNA molecule. This generates sticky ends, which have single-stranded overhangs. These sticky ends can then bind with complementary sticky ends generated by the EcoRI enzyme when it cuts another DNA molecule, allowing for the formation of recombinant DNA in molecular biology techniques like cloning.
The digestion of calf liver DNA with EcoRI allows for the isolation of specific DNA fragments and can be used in various molecular biology experiments, such as DNA sequencing, gene mapping, and genetic engineering.
