Picture 2. This image is of two replication forks for a human X chromosome. In this image, red letters are RNA nucleotides and black letters are DNA nucleotides. The shapes with boxed numbers pointing to them represent enzymes in the DNA replication process, though their shapes are not true to shapes seen on molecular levels.
Based on Picture 2, how many places along the human X chromosome can replication start?
Looking at Picture 2, enzyme 2 is primase. When enzyme 3 starts working at the site that enzyme 2 is at, will enzyme 3 add to the G or to the U?
Enzyme 3 is building the leading strand for which replication fork in Picture 2?
Where would enzyme 2 go to work next?
Picture 3: This image is of two replication forks for a human X chromosome. In this image, red letters are RNA nucleotides and black letters are DNA nucleotides. The shapes with boxed numbers pointing to them represent enzymes in the DNA replication process, though their shapes are not true to shapes seen on molecular levels.
Where will an Okazaki fragment get made in picture 3?
Are the DNA polymerase III’s in picture 3 building leading or lagging strands?
How many places shown in this image can another DNA polymerase III work?
Picture 4: This image is of two replication forks for a human X chromosome. In this image, red letters are RNA nucleotides and black letters are DNA nucleotides. The shapes with boxed numbers pointing to them represent enzymes in the DNA replication process, though their shapes are not true to shapes seen on molecular levels.
