The figure above shows an organelle typically found in eukaryotic cells.  Which of the following best describes the function of the double membrane system of this organelle?

Labeled nucleotides were supplied to a cell culture before the cells began DNA replication.  A simplified representation of the process for a short segment of DNA is shown in Figure 1.  Labeled DNA bases are indicated with an asterisk (*).  Which of the following best helps explain how the process represented in Figure 1 produces DNA molecules that are hybrids of the original and newly synthesized strands? (Hint: template refers to the parent strand that is used to make a copy)

Which enzyme unzips the DNA double helix during replication?

What part of the cell cycle would a cell be in if there are visible Okazaki fragments and active DNA polymerase found within?

Why is chemiosmotic phosphorylation in photosynthesis also called photophosphorylation?

Which strand is synthesized continuously during DNA replication?

Nucleotide base pairing in DNA is universal across organisms.  Each pair (T-A; C-G) consists of a purine and a pyrimidine.  Which of the following best explains how the base pairs form?

If the nucleotide sequence on one side of DNA reads as follows, give the nucleotide sequence of the opposite strand – start from left to right on the opposite strand, use capital letters only and do NOT use the space bar in your answer. CCGATCAAG

What structure within the chloroplast contains photosynthetic pigments?

What enzyme is responsible for connecting the Okazaki fragments on the lagging strand?
