Lab: Building Proteins from RNA

Question 1

You transcribed DNA to make tRNA✔ mRNADNAprotein

Revolt · Accepted Answer

✔ mRNA; mRNA; translation.

Question 2

and built a sequence of amino acids through tRNA.lipids.✔ translation.mRNA.

Revolt · Accepted Answer

✔ translation.

Question 3

Question 3

Revolt · Accepted Answer

base "words" that code for specific amino acids. They are: 3; and never: nonoverlapping; the words.: have gaps between

Question 4

overlapping✔ nonoverlapping and never

Revolt · Accepted Answer

✔ nonoverlapping

Question 5

✔ have gaps betweenrepeat the words.

Revolt · Accepted Answer

✔ have gaps between

Question 6

Question 6

Revolt · Accepted Answer

direction,: 3' to 5'; direction.: 5' to 3'

Question 7

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

Revolt · Accepted Answer

✔ RNA

Question 8

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

Revolt · Accepted Answer

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

Question 9

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

✔ 3' to 5'; direction,: 3' to 5'; direction.: 5' to 3'

Question 10

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.
