Put the following steps of DNA replication in order. Question 1 options:

As a result, one strand (the leading strand) is replicated continuously in the 5´ to 3´ direction in the same direction that the replication fork is moving.

Replication ends with each new molecule of DNA containing one parent strand and one new strand.

Replication begins with a specific nucleotide sequence called the replication origin.

The other strand, known as the lagging strand, is replicated in short segments, still in the 5´ to 3´ direction, but away from the replication fork.

When replication is complete, DNA polymerase dismantles the RNA primer and proofreads the nitrogen base pairing of the two new DNA molecules.

These fragments, called Okazaki fragments, are spliced together by DNA ligase.

New DNA strands are produced when an enzyme called DNA polymerase inserts into the replication bubble. A primase enzyme synthesizes an RNA primer that serves as the starting point of new nucleotide attachment by DNA polymerase

DNA polymerase can only synthesize the new nucleotide chain in the 5´ to 3´ direction.

The helicases cleave and unravel a section of the original double helix, creating Y-shaped areas (replication forks) at the end of the unwound areas, which form a replication bubble.

A group of enzymes, called the helicases, bind to the DNA at each replication origin.

Scenario 5 1) take 10 red and 10 black beans and place them, mixed, on the table. record the starting phenotype # and frequencies (% of your total population) of your starting population in the table provided (generation 0). 2) act as a predator. “capture” as many organisms as you can until you have reduced the population to three organisms. put them aside. at this point, the predators die. 3) the remaining organisms each produce 2 clonal offspring. multiply your organisms accordingly and allow them to mix on the table. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 1). 4) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 2). 5) repeat the reproduction event, allowing each of your organisms to produce 2 clonal offspring. calculate and record the resultant phenotype # and frequencies (% of your total population) of your population in the table provided (generation 3).
