Question 1

What is the author’s purpose for writing "Your DNA at Work"?

Revolt · Accepted Answer

to describe how proteins are produced

Question 2

How does the author organize the text or ideas in the article? Select three options.by using paragraphs to focus on ideasby using images that help explain or focus on an ideaby using an outline to list the steps in a processby using a table to show steps in a processby using subheadings to separate steps in a process

Revolt · Accepted Answer

by using paragraphs to focus on ideas; by using images that help explain or focus on an idea; by using subheadings to separate steps in a process

Question 3

Where in the cell do transcription and translation take place?

Revolt · Accepted Answer

Transcription takes place in the nucleus, and translation takes place in ribosomes.

Question 4

Which molecule involved in protein synthesis was mentioned in "Our Molecular Selves" but not in "Your DNA at Work"?

Revolt · Accepted Answer

tRNA

Question 5

Which statements describe proteins? Select three options.

Revolt · Accepted Answer

Proteins are created from the code in DNA.; Amino acids are the building blocks of proteins.; Proteins affect the structures and functions of living things.

Question 6

Use information from the lesson and article (Transcription and Translation on pages 3 and 4, respectively) to answer the question. Which statements differentiate DNA and RNA? Select three options.DNA is a double helix, and RNA is a single strand.DNA moves in and out of the nucleus, and RNA stays in the nucleusDNA is involved only in transcription, and RNA is involved in both transcription and translation.DNA is involved in both transcription and translation, and RNA is involved only in translation.DNA does not have uracil as a nitrogen base, but RNA does have uracil as a nitrogen base.

Revolt · Accepted Answer

DNA is a double helix, and RNA is a single strand.; DNA is involved only in transcription, and RNA is involved in both transcription and translation.; DNA does not have uracil as a nitrogen base, but RNA does have uracil as a nitrogen base.

Question 7

The transcription of the information in DNA involves the pairing of the nitrogen bases of DNA with RNA nucleotides to form a molecule of messenger RNA. Review this pairing process on page 3 of the article under the subheading “Transcription.” Then, complete the pairing activity below. Choose the RNA nitrogen bases that pair with the DNA nitrogen bases listed. Be sure to use the capital letters that represent the nitrogen bases. A pairs with . C pairs with . T pairs with .
