Unit 5 Test Remediation

Mei started feeling sick at school and the school nurse called her mom and suggested that they come by the clinic. Mei tested positive for the Influenza virus. She will need to allow her body to fight off the infection. In order to fight it, she would need to make antibodies, which are proteins. Which of the following describes the proper steps needed for Mei's cells to make these influenza antibodies?

• Nucleus, Rough ER, Golgi apparatus, Vesicle
• Rough ER, Golgi apparatus, Vesicle, Nucleus
• Golgi apparatus, Rough ER, Nucleus, Vesicle
• Vesicle, Nucleus, Golgi apparatus, Rough ER

In a model of a DNA molecule created by students Hannah and Rohan, there are four parts labeled below. What can be inferred about the bonds between 1 and 2 versus the bonds between 3 and 4?

• The bonds between 3 and 4 are weaker because they are held by hydrogen bonds

• The bonds between 1 and 2 are weaker because they are held by covalent bonds

• The bonds between 1 and 2 are stronger because they are held by hydrogen bonds

• The bonds between 3 and 4 are stronger because they are held by covalent bonds

In a recent biology project, David, Aria, and Hannah were analyzing the DNA of several organisms. They noticed some values were missing from their data table. According to Chargaff’s rule, if they were to determine the amount of guanine bases in chicken DNA, what percentage should it be?

• 29%

• 20%

• 21%

• 13%

Fill in the blanks with the correct set of words below: In a high school biology class, Henry and Nora are learning how DNA replicates itself. They learn that the nitrogen bases of DNA, T-A and C-G, act as a template in building new DNA molecules during replication. But before replication can begin, an enzyme called ________ must _____________, starting at the replication origin.

• DNA primase; split open the DNA

• DNA polymerase; match nitrogen bases

• helicase; split open the DNA

• ligase; insert the correct nitrogen bases

Maya is conducting an experiment in her biology class to extract DNA from a sample of bacteria collected from a local pond. After several steps, she obtains a preparation that contains only four types of molecules. Based on the characteristics listed in her lab notebook, molecule 2 would most likely be which type of molecule?

• DNA

• RNA

• carbohydrate

• protein

During a high school science project, Nora and Noah were examining the DNA segment of a fruit fly. They noticed a mutation similar to the one described here. What type of mutation has occurred? If this DNA molecule proceeds to transcription and translation, explain the impact of this mutation on the production of a protein?

• This is a point mutation, resulting from the addition of one nitrogen base. This strand can no longer be used for transcription or translation due to its mutation.

• This is a frameshift mutation, resulting from the substitution of one nitrogen base. If this strand of DNA is used for transcription, it will result in all of the amino acids being placed incorrectly in the protein.

• This is a frameshift mutation, resulting from the addition of one nitrogen base. This strand can no longer be used for transcription or translation due to its mutation. If this strand of DNA is used for transcription, it will affect the coding of multiple amino acids, causing an incorrect protein to be assembled.

• This is a point mutation, resulting from the substitution of one nitrogen base. If this strand of DNA is used for transcription, it will affect the coding of ONE amino acid, resulting in placing the correct amino acid in the protein, placing the wrong amino acid in the protein, or coding for the protein to stop building.
