DNA replication results in two DNA molecules.

• each with 2 new strands
• one with two new strands, and the other with two original strands
• each with one new strand and one original strand
• each with two original strands

During normal mitotic cell division, a parent cell having four chromosomes will produce two daughter cells each containing ...

• two chromosomes
• four chromosomes
• eight chromosomes
• sixteen chromosomes

The process of mitosis normally results in the production of...

• two cells with the same number of chromosomes as the original parent cell
• only one cell with a copied set of homologous chromosomes
• two cells with only one type of chromosome
• four cells with half the number of chromosomes as the parent cell

Two researchers, Maurice Wilkins and Rosalind Franklin, used X-ray crystallography to make pictures of DNA such as the one shown.  The picture shows an X-ray diffraction pattern of DNA.  This type of image helps show that DNA...

• is a double helix
• is very large
• is made of codons
• contains deoxyribose

Compared to small cells, large cells have more trouble

• dividing
• producing daughter cells
• diffusing needed material in and waste products out
• making copies of their DNA

Chargaff's requirement that A=T and G=C suggested that...

• cytosine molecules pair up with guanine molecules, and thymine molecules pair up with adenine molecules
• the two strands of DNA run in opposite directions
• the number of adenine molecules in DNA relative to the number of guanine molecules differs from one species to the next
• the replication process must necessarily be semi-conservative

The jimsonweed Datura stramonium normally has 12 chromosomes in the body cells.  If the body cell divides, how many chromosomes will the two daughter cells each have?

• 6 chromosomes
• 12 chromosomes
• 18 chromosomes
• 24 chromosomes

• when the centrioles move to the poles
• when the cell organelles are duplicated
• when the nucleus divides
