When there are unbonded ends of the dna, they are called

these sticky ends allow us to insert

The unbonded terminals of the DNA are known as sticky ends. They are called sticky as they exhibit complementary bases. The generally used restriction enzymes cleave the two complementary strands of DNA at distinct locations, producing sticky ends or overhangs.  

These sticky ends permit for perfect base pairing and it takes place due to hydrogen bonding. These sticky ends permit one to insert DNA. These sticky ends play an essential role in molecular cloning as they make sure that the fragment of DNA is administered into the plasmid in an accurate direction.  

as in mitosis, dna replication occurs during interphase.   in meiosis, it occurs specifically in s phase of interphase 1.

ionic bonds are two oppositely charged ions that attract. a sodium ion has a 1 positive charge; a chloride ion has a 1 negative charge. sodium and chloride have oppostive charged ions that attract which forms an ionic bond. a chemical bond formed when two atoms share electrons is called
