Chapter 8: From DNA to Proteins

Figure 8.1 shows a single strand of DNA. Identify the nucleotide sequence of the other DNA strand.

• GGCUTGU

• AATGCAG

• GGCATGA

• TTACGTC

Figure 8.2 shows a single strand of DNA. Identify the nucleotide sequence of the complementary RNA strand

• ATUTUAG

• CAAGACT

• AUCUCAG

• ATCTCAG

In which part of the cell does this process shown in Figure 8.3 take place?

• in the nucleus

• in food vacuoles

• at the ribosomes

• on the chromosome

The process illustrated in Figure 8.3 is called _____.

• translation

• replication

• monoploidy

• transcription

Which series is arranged in order from largest to smallest in size?

• chromosome, nucleus, cell, DNA, nucleotide

• cell, nucleus, chromosome, DNA, nucleotide

• nucleotide, chromosome, cell, DNA, nucleus

• cell, nucleotide, nucleus, DNA, chromosome

Which of the following sequences of processes correctly reflects the central dogma?

• protein synthesis, transcription, translation

• protein synthesis, translation, transcription

• transcription, translation, protein synthesis

• translation, transcription, protein synthesis

What did Hershey and Chase know about bacteriophages that led them to use these viruses in their DNA experiments?

• bacteriophages are made up of a protein coat surrounding DNA

• sulfur in all bacteriophages is radioactive

• protein from bacteriophages enters bacteria

• bacteriophages have no DNA of their own

How did Hershey and Chase's use of radiolabeled bacteriophages to study the genetic material validate Avery's research?

• it demonstrated conclusively that the genetic material is not protein

• it showed that bacteriophages are not digested by bacterial enzymes

• it proved that bacteria will take up phosphorus, but not sulfur

• it confirmed that bacteriophages cannot inject radiolabeled DNA

The main difference between the four nucleotides that make up DNA is that they have different

• sugars

• uracil

• bonds

• bases

Which scientists figured out the three-dimensional structure of DNA by using a model of metal and wood?

• Hershey and Chase

• Watson and Crick

• Pauling, and Franklin

• Chargaff and Griffith
