Answer #1

1. Replication of DNA follows semiconservative model. Both daughter DNA synthesized from parent DNA contains half of their content from parents. A single strand of parent DNA act as template on which a complimentry strand is formed and thus no any nucleotide miss in the daughter DNA. ​For better unserstanding see the attached image.

2. SSB proteins (single stranded binding proteins) cover the separated strands of DNA near the replication fork, keeping them from coming back together into a double helix and thus keep both the strands separated. Helicase opens the double stranded DNA.

Restriction enzymes, also known as restriction endonucleases, are enzymes that cut a DNA molecule at a particular place. They are essential tools for recombinant DNA technology. The enzyme "scans" a DNA molecule, looking for a particular sequence, usually of four to six nucleotides. Once it finds this recognition sequence, it stops and cuts the strands. This is known as enzyme digestion. On double stranded DNA the recognition sequence is on both strands, but runs in opposite directions. This allows the...
