SB2 DNA, Genetic Variation, Biotechnology Review

When comparing the offspring of sexually and asexually reproducing organisms, we would expect the genetic material (DNA) of the sexually reproducing organism to -

• contain fewer mutations
• be lesser in quantity
• be simpler overall
• show more variation

Which of the following is an example of a beneficial (good) mutation?

• When an organism's lifespan becomes shorter

• When an organism becomes unable to reproduce

• When an organism's body becomes deformed

• When an organism develops immunity to a disease

Two humans believe they are related. Which would be the best technique to determine if they are related? 

• testing blood types
• comparing DNA
• examining karyotypes
• testing for genetic disorders

A scientist cloned a goat. Which of these is a true statement about the cloned goat?

• It has new genes and traits
• It lacks the genes for reproduction
• It has the genes that are identical to the original goat
• It looks the same but has different genes.

Using a virus to enter a cell and replace defective genes with healthy genes is called

• tissue culturing
• bioremediation
• cloning
• gene therapy

A method of separating DNA fragments according to their size and charge using an electric current passed through a gel containing the samples a

Which process is shown in the image?

• crossing over

• independent assortment

• segregation

• mutation

The offspring from asexually reproduced organisms are?

• Different than their parents
• Identical to parents
• Like a combination from both parents
• A different species

If two organisms reproduce sexually, then their offspring will exhibit a genetic makeup that is -

• identical to only one parent
• identical to all of its siblings
• a unique combination of traits
• the recessive traits of each parent

DNA is often considered the "______________" of life.
