Use the following template strand of DNA and the coding table to determine the correct amino sequence and write this sequence be
REY [17]

DNA and RNA have the main difference in the presence of deoxyribose sugar in DNA and ribose sugar in RNA. One more is the presence of thymine in DNA while the presence of uracil in RNA.

<h3>What is the codon?</h3>

Codon is actually a three-letter code which is a sequence of three consecutive nucleotides in a DNA or RNA molecule which generally codes for a specific amino acid.

The DNA sequence given here is:

T A T A T C T A C G G T C C G G C A T C G A T T T C G

So the RNA sequence for this will be:

A U A U A G A U G C C A G G C C G U A G C U A A A G C.

So according to the table, the amino-acid sequence will be:

Isoleucine STOP Methionine Proline Glycine Arginine Serine STOP Serine.

Generally stop codon is responsible for the termination of protein synthesis.

Thus, this was the amino acid sequence for mRNA according to the given DNA sequence.

A student wants to find out if the amount of bleach has an effect on stain removal.
Step2247 [10]

Answer:

The second option.

Explanation:

We're trying to test the amount of bleach that has an effect on the stain so that is the altered variable.

The 2nd option uses different amounts of bleach to clean the same amount of stain.

If you choose the other options, people can argue that the bigger stain would be harder to clean with one cup of bleach, whereas the small stain gets two cups or the other way around.

It's not an effective way to see if the amount of bleach has an effect on stain removal.
