What is happening to the DNA molecule in the figure? (Explain the first step in DNA replication)
tatuchka [14]

Answer:

As this is DNA replication, this is the unwounding process

Explanation:

In DNA replication, the parent DNA to be replicated is unwound to enable access of the replication machinery (replisome) to this genetic material. The origin of replication will be identified first, which in the prokaryotes is only one, and in the eukaryotes, we have many. This sites are recognized by specific sequences on the genome. after this, melting of the DNA occurs at this origin creating a replication bubble and two replication forks. This  allows for the unwinding of the DNA by the enzyme Helicases in the direction of the replication fork. Another enzyme present in this step is also the single strand binding proteins (SSB). These proteins function in the prevention of re-anealing of the unwound DNA strand by attaching themselves to each strands. Another enzyme called the topoisomerases also function here by reducing the torque (twisting) produced upstream of the replication fork as result of DNA unwounding. An example is the gyrase

ANEK [815]

Answer:

you would use your muscles from your legs and your body to get up from your bed and go to your fridge, your muscular system helps you up by being a structure for the muscles to apply force, you will use arm muscles for getting out cookies and milk. Then you will drink and eat your cookies and milk with your jaw muscle and send it down your esophagus to the intestines for the digestive system to break down your food. Then you will use your legs(muscles) to go back to your bed and sleep. (don't copy this whole thing it is not complete and you must add stuff so it is complete im just giving you an idea or the structure of this essay)
