Name: __________________________________________ Date: _______________ Quiz name: DNA Structure, Replication, and Protein Synthesis 1. In DNA, the nitrogen base Guanine (G) always bonds with the nitrogen base A Adenine (A) B Cytosine (C) C Thymine (T) 2. In DNA, the nitrogen base Thymine (T) always bonds with A Adenine (A) B Cytosine (C) C Guanine (G) If the sequence of nucleotides on one strand of DNA is GCCTATC, what is the sequence on the complementary strand? 3. A GGGTATG B CGGATTC C CGGTAAC D CGGATAG 4. The building block, or monomer, of DNA is called the A amino acid B RNA C nucleotide D simple sugars 5. DNA contains the instructions for making A proteins B sugars C lipids D genetics 6. Which of the following is an example of a nucleotide? A phosphate, ribose sugar, cytosine B phosphate, deoxyribose sugar, cytosine and guanine C phosphate, deoxyribose sugar, cytosine D cytosine, guanine, thymine, and adenine 7. The weak bonds between nitrogen base pairs in DNA are A covalent bonds B hydrogen bonds Page 1 of 3 C ionic bonds D nitrogen bonds 8. DNA replication results in two DNA molecules, A each with two new strands. B one with two new strands and the other with two original strands. C each with one new strand and one original strand. D each with two original strands. 9. RNA is different from DNA because RNA A has one strand of nucleotides instead of two B has the sugar ribose instead of deoxyribose C has the base Uracil instead of Thymine D all of the above 10. The monomer of proteins are called A nucleic acids B nucleotides C amino acids D simple sugars 11. Transcription takes place in the A cytoplasm B nucleus C ribosome D cell membrane 12. Translation takes place A in the cell membrane B on a ribosome C in the nucleus 13. During transcription, A a DNA copy is made from mRNA. B a protein is formed. C a mRNA is made from DNA. D DNA is replicated. 14. 15. What happens during the process of translation? A Messenger RNA is made from DNA. B The cell uses information from messenger RNA to produce proteins. C Transfer RNA is made from DNA. D Copies of DNA molecules are made. The mRNA copy of the DNA strand GCCATCG is Page 2 of 3 16. A CGGTAGC B CGGUAGC C GCCAUGC D CGGTUGC Why is RNA used as the messenger molecule to carry the information to a ribosome for protein synthesis? Page 3 of 3
