Review

What phase is  shown in the picture?

• anaphase 1
• anaphase 2
• metaphase 1
• telophase 1

The process of crossing over occurs in what phase of meiosis?

• anaphase 1
• prophase 1
• prophase 2
• telophase 1

This image shows chromosomes during Prophase 1. Which of the following correctly describes the process shown?

• segregation of sister chromatids
• condensation and segregation of alleles
• mutationin which the DNA content of the gene is altered
• crossing - over in which alleles are exchanged

The correct order of the phases of mitosis and meiosis could be abbreviated as:

• MAPT
• PAMT
• TPAM
• PMAT

Which of the following phases of mitosis is represented by the diagram below?

• prophase
• metaphase
• anaphase
• telophase

Plasmids are found in bacteria. Scientists use plasmids to 

• Insert eukaryotic  genes into bacteria
• insert eukaryotic genes into humans
• insert clones into the parent organism

T6- Which technology below would probably be the most important to a person who had diabetes and had to take insulin every day? 

• using recombinant DNA to produce human hormones from bacteria
•  testing parents for genetic disorders before they have children
• engineering fruits and vegetables that resist insects and other pests
• C. developing ways to identify criminals through DNA fingerprinting

T6- How do scientists cut DNA into smaller strands?

• restriction enzymes
• scissors
• ligase
• agarose

T6- In order to insert a human gene into plasmid, both must 

• code for the same gene product.
• be cut by the same restriction enzyme.
• originate from the same type of cell.
• have identical sequences.

Which enzyme "glues" DNA fragments together?

• restriction enzymes
• DNA ligase
• DNA polymerase
• DNA helicase
