DNA vs. RNA Practice

What is the role of mRNA in expressing specialized structures?

• making energy available for cellular activities

• creating bonds to form biomolecules

• producing sugars that assist with replication

• carrying information to form proteins

Cell differentiation is most directly regulated by...

• ATP

• DNA

• RNA

• sugars

Match the factor to the appropriate column

Groups:

(a) DNA

,

(b) Both

,

(c) RNA

• Helps to build proteins

• Double stranded

• Deoxyribonucleic acid

• Base Pairs: adenine, uracil, guanine, cytosine

• Ribonucleic acids

• Has a sugar, phosphate, and a base

• Nucleic acids

• Is found in all living things

• Has a messenger and transfer type

• Stays inside the nuclues

• Singe stranded

• Bases Pairs: adenine, thymine, guanine, cytosine

Which components must be combined with a phosphate group to form an adenine nucleotide in DNA?

Select all that apply

• Deoxyribose sugar

• Uracil base

• Ribose sugar

• Adenine base

• Thymine base

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 double-helix shape of the condensed chromosome

• In the ration of adenines to thymines

• As a pattern of phosphates and sugars

The photograph shows a laboratory investigator examining samples of DNA in a procedure called PCR, or polymerase chain reaction. Using PCR, the investigator can create thousands or millions of copies DNA for closer investigation.

In which of these situations would PCR be most useful?

• When only a small amount of DNA is available, such as at a crime scene.

• When the DNA of identical twins is being mapped.

• When the genome of a population is being analyzed for preventable diseases.

• When the blood type of a DNA donor is known.

The results in the picture were obtained using a technique known as gel electrophoresis. This technique separates mixtures of DNA. In the picture nine different samples of DNA are compared.

Gel electrophoresis can be used to...

• determine the difference in ages of a set of people

• identify how closely two individuals are related

• determine how effective certain medications are

• identify different blood types
