  1. How much do you know about genes?

  2. Which of the following is NOT on DNA? thymine deoxyribose guanine adenine uracil

  3. __ is when the mRNA is decoded by tRNA so that amino acids can line up? interphase photosynthesis replication transcription translation

  4. What did James Watson do? Discovered that replication is semi-conservative Identified the location of the nuclear pores Discovered that thymine always bonds with adenine Took x ray pictures of DNA Discovered that DNA is a double helix

  5. Which of the following might be a rung on DNA? Adenine and uracil Ribose and deoxyribose Deoxyribose and thymine Thymine and uracil Cytosine and guanine

  6. Cytosine is complementary to? plurine thymine adenine uracil guanine

  7. Which of these is NOT a reason why Mendel used peas? Easy to cross pollinate Many observable traits Easily observed traits Quick reproduction Contain only eggs or sperm

  8. __ is semi-conservative? A, B, and C A and B translation transcription replication

  9. An anticodon is 3 bases on ? DNA mRNA pRNA dRNA tRNA

  10. Because adenine always bonds with thymine, we call adenine and thymine __ base pairs. expository mandatory supplementary explanatory complementary

  11. Replication takes place in the ? Ovaries ribosome cytoplasm Endoplasmic reticulum nucleus

  12. Proteins are made of chains of? DNA glucose incorrect nucleotides Amino acids

  13. What happens when a true-breeding plant self-pollinates? All of the above None of its offspring have the same traits as the parent. Some of its offspring have the same traits as the parent. One of its offspring has the same traits as the parent. All of its offspring have the same traits as the parent.

  14. What did Francis Crick do? Discovered that replication is semi-conservative Identified the location of the nuclear pores Discovered that thymine always bonds with adenine Took x ray pictures of DNA Discovered that DNA is a double helix

  15. A plant with two dominant OR two recessive alleles is said to be Cross pollinating heterozygous Self pollinating alleles homozygous

  16. What is a phenotype? The alleles contained by the organism The way an organism feels A dominant gene A group of 5 alleles The way an organism looks

  17. Which of these might be on the sides of the DNA ladder? Peptide bond tRNA uracil guanine phosphate

  18. What does DNA do? All of the above Controls what moves in and out of cells Contains the enzymes responsible for digestion Produces proteins Carries the blueprint for making proteins

  19. __ is when one gene of DNA is copied to make mRNA? mitosis photosynthesis translation replication transcription

  20. Translation takes place in the? nucleus Hydrogen bond Golgi apparatus lysosome ribosome

  21. A string of nucleotides that has the instructions for a certain trait is a? homozygous cell dominant chloroplast gene

  22. 3 bases code for one organelle protein DNA cell Amino acid

  23. In Mendel’s parent cross, he tested a true breeder long with a true breeder short. The offspring were 25% tall, 50% medium, 25% short 75% tall, 25% short 100% medium 75% short, 25% tall 100% tall

  24. 2 bases on DNA are held together by? gravity A nitrogen bond A peptide bond Amino acids A hydrogen bond

  25. Which of the following is NOT on DNA? thymine deoxyribose phosphate adenine ribose

  29. Amino acids are connected by? Rock bands Rubber bands Nitrogen bonds Hydrogen bonds Peptide bonds

  30. What did Maurice Wilkins do? Discovered that DNA is a double helix Discovered that cytosine always bonds with guanine Discovered the chemical structure of the phosphate molecule Used the word “cell” when looking through a microscope Took x ray pictures of DNA

  31. Which of the following is a heterozygous genotype? WW No widow’s peak ww Widow’s peak Ww
