State whether the following statements is true/false regarding DNA replication.
1. In E. coli replication begins at the origin of replication and proceeds in one direction until the entire circular DNA molecule has been copied.
2. The chromosome of the fruit fly (D. melanogaster) is about twice as large as the E. coli chromosome.
3. Prokaryotic DNA replication occurs in two steps. First, ATP provides a phosphate to the growing DNA chain. This is followed by addition of a nucleoside.
4. DNA polymerase III is the largest DNA polymerase in E. coli.
5. The β subunits of E. coli DNA polymerase form a sliding clamp that surrounds the DNA strands at the replication fork.

#Unit 9. Diversity of Life Forms
In angiosperm plants, flower morphology can be very intricate. If a tree, such as a New Mexico locust, has flowers that share many morphological intricacies with flowers of the sweet pea vine, then the most likely explanation for these floral similarities is the same general explanation for the similarities between the

#Unit 8. Inheritance Biology
In watermelons, bitter fruit (B) is dominant over sweet fruit (b), and yellow spots (S) are dominant over no spots (s). The genes for these two characteristics link at 30 map unit. A homozygous plant that has bitter fruit and yellow spots is crossed with a homozygous plant that has sweet fruit and no spots. If an F1 plant is backcrossed with the sweet fruit, no spot parent, what are the phenotypes ratio expected in the their offspring
