Lab: Building Proteins from RNA

Question 1

You transcribed DNA to make

Revolt · Accepted Answer

mRNA; Selection 1: mRNA; Selection 2: translation.

Question 2

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

Revolt · Accepted Answer

✔ translation.

Question 3

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

Revolt · Accepted Answer

✔ RNA

Question 4

Revolt · Accepted Answer

✔ nonoverlapping

Question 5

✔ have gaps betweenrepeat the words.

Revolt · Accepted Answer

✔ have gaps between

Question 6

Number the steps in the correct order (1 through 5). Transcribe the DNA to create the mRNA. Match the mRNA codons to their tRNA anticodons and the attached amino acids. Perform dehydration synthesis to build the amino acid chain in the ribosome. Locate the start, stop, and other codons on the mRNA. Identify the antisense strand of the DNA within the cell nucleus.

Question 7

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

Revolt · Accepted Answer

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

Question 8

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 9

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

Revolt · Accepted Answer

✔ 5' to 3'

Question 10

There is a certain grammar to the genetic code, or rules to follow so that the message can be effectively translated from DNA into functional protein.Codons are 234 base "words" that code for specific amino acids. They are

Revolt · Accepted Answer

3; base "words" that code for specific amino acids. They are: 3; and never: overlapping; the words.: repeat
