Enzymes are considered to be...

• Lipids

• Proteins

• Carbohydrates

• Nucleic Acids

What biomolecule provides our cells with genetic instructions?

• Lipids

• Proteins

• Nucleic Acids

• Carbohydrates

What does NOT happen during interphase?

• growth of the cell

• obtaining nutrients

• cell division

• DNA replication

What phase of mitosis is this?

• Prophase

• Metaphase

• Anaphase

• Telophase

What letter represents cell division phase of the cell cycle?

• A

• B

• C

• D

A segment of DNA is represented in the illustration. How is information for a specific protein carried on the DNA molecule?

• as a sequence of nucleotides

• in the ratio of nitrogenous bases Thymine/Adenine

• In the double helix shape of condensed chromosomes

• as patterns of phosphates and sugars

The back bone of a DNA structure are NOT made of

• phosphate

• sugar

• nitrogenous bases

• ribose

The process of this question is represented above. The aforementioned process in which DNA makes a copy of messenger RNA is called:

• translation

• mitosis

• translocation

• transcription

Translation is crucial to the process of making proteins. Which statement best describes what takes place during translation?

• A copy of chromosomal DNA is created

• A RNA copy of a DNA strand is made.

• Information in mRNA is converted into a sequence of amino acids in a protein

• Instructions from DNA in the nucleus are brought to the cytoplasm

Use the information provided in the chart above and your knowledge of biology to answer questions which follow. The diagram represents molecular structures involved in protein synthesis.

Structure 1 represents

• part of a polypeptide chain

• a portion of a DNA molecule (or gene)

• a portion of an RNA molecule

• the building blocks of proteins
