Transcription creates an mRNA molecule using DNA as as a template. Where does this process occur in cells of eukaryotes?

• in the nucleus

• in the cytoplasm

• in the ribosomes

• in the Golgi apparatus

DNA replication results in two separate DNA molecules. How are the DNA molecules at the end of the process related to the DNA molecule at the begining of the process?

• One strand of the original DNA molecule becomes one strand in each of the new DNA molecules ,While each other strand is made from cytoplasmic nucleotides

• Both strands of the original DNA molecule are stripped of their nitrogenous bases and each strand of the new DNA molecules is made using cytoplasmic bases

• Both strands of the original DNA molecule are broken down to their nucleotides and each strand of the new DNA molecules made from cytoplasmic nucleotides

• Both strands of the original DNA molecule are in one of the new DNA molecules and the other new DNA molecule is constructed from cytoplasmic nucleotides

At the cellular level ,lipids are the primary component of the cell membrane. Which statement would BEST support the argument that the structure of a lipid is related to this function?

• Lipids contain many hydrogen bonds

• Lipids are insoluble

• Lipids are constructed to store genetic information

• Lipids are composed of amino acids

A student investigated photosynthesis .In her lab report, she wanted to add a diagram summarizing the process. Which flow chart provides the BEST summary of photosynthesis.

• Carbon + Water + Oxygen = Carbohydrates

• Carbon + Water = Carbohydrates and Oxygen

• Carbon Dioxide + Water = Carbohydrates and Oxygen

• Water + Oxygen = Carbohydrates and Carbon Dioxide

Which statement describes the products of meiosis I and II?

• Meiosis I produces two haploid cells, and meiosis II produces four haploid cells

• Meiosis I produces four diploid cells, and meiosis II produces four haploid cells

• Meiosis I produces two diploid cells, and meiosis II produces four haploid cells

• Meioisis I produces two diploid cells, and meiosis II produces two daughter cells

What is a mutation?

• A change in genetic material of a cell

• The specific sequence of bases in a molecule of DNA

• The process by which a molecule of DNA makes a copy of itself

• The perfect replication of a DNA molecule

Consider this DNA nucleotide sequence: ACG GTT CTA GAC Which mutation will result in a frame shift?

• Substitution of T for the first A in a frame shift

• Deletion of GTT from the sequence

• Insertion of C at the start of the sequence

• Substitution of ATA for ACG in the sequence
