What is one advantage of sexual reproduction?

• offspring are identical to parents
• offspring are resistant to viruses
• offspring are born live, rather thna from eggs
• offspring inherit a wider variety of genetic information

What is the purpose of Strand A?

• to act as a template for the synthesis of messenger RNA

• to carry the code from the DNA molecule in the nucleus to the ribosome

• picks up and transfers specific amino acids to the ribosome

• picks up and transfers nucleic acids to the nucleus

What mRNA sequence will best match the section of DNA shown?

• C-T-A-G-G-C

• C-U-A-G-G-A

• A-G-C-U-U-C

• T-C-G-A-A-G

• Methionine

• Serine

In many humans, exposing the skin to sunlight over prolonged periods of time results in the production of more pigment by the skin cells (tanning). This change in skin color provides evidence that -

• the inheritance of skin color is an acquired characteristic.
• albinism is a recessive characteristic.
• ultraviolet light can cause mutations.
• the environment can influence gene action.
