Lab: Building Proteins from RNA

Question 1

You transcribed DNA to make and built a sequence of amino acids through

Revolt · Accepted Answer

B: mRNA

Question 2

Check all ways below to ensure that the bases in RNA are properly paired.

Revolt · Accepted Answer

B: The mRNA strand is complementary to the DNA template strand.; C: During transcription, G in DNA pairs with C in mRNA, and A in DNA pairs with U in mRNA.

Question 3

Chains of nucleic acids have directionality and are read in a certain way just like languages are read from "left to right" or "right to left."DNA is always read in the ✔ 3' to 5'5' to 3' direction,

Revolt · Accepted Answer

A: 3' to 5'

Question 4

Identify the antisense strand of the DNA within the cell nucleus.

Revolt · Accepted Answer

⇒ 2: 1

Question 5

Suppose the following amino acid chain was created based on a student's transcription and translation:Tyr-Leu-Pro-MetIn the chain, which data show a possible source of error? Explain the error.

Revolt · Accepted Answer

The position of Met seems incorrect. The amino acid sequences of all proteins begin with Met because it is the amino acid that is attached to the anticodon for the AUG start codon. It looks like the student might have worked in a backward direction for transcription.

Question 6

How could you be sure you have located a section of DNA that encodes for a protein?

Revolt · Accepted Answer

B: Allow the DNA to be transcribed to RNA and see what protein results.

Question 7

and built a sequence of amino acids through

Revolt · Accepted Answer

C: translation.

Question 8

whereas RNA is read in the 3' to 5'✔ 5' to 3' direction.

Revolt · Accepted Answer

B: 5' to 3'

Question 9

Question 10

The sequence of amino acids was controlled by the information in the molecules.
