Answer:

There is actually more than one difference because DNA uses deoxyribose and RNA uses ribose PLUS DNA has thymine and RNA uses uricale

Find the mean, median, and mode of the following list of values. Round to the nearest tenth if necessary.

grin007 [14]

Answer:

D.

Mean: 24.8

Median: 26

Mode: 26

Explanation:

The mean is the average. To find the average, add up all the numbers and divide by the amount of numbers there are.

30 + 26 + 25 + 11 + 34 + 20 + 26 + 26 = 198

Now, we divide by how many numbers we started out with (8).

198 divided by 8 = 24.75, rounded would be 24.8

To find the median, you arrange the numbers from smallest to largest, and find the middle number like this:

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the middle number is 26.

To find the mode, you arrange the number from smallest to largest, and find the number that appears more often.

11, 20, 25, 26, 26, 26, 30, 34

As you can see, the number 26 appears the most often.

So, we end up with:

Mean: 24.8

Median: 26

Mode: 26

This table shows the codons found in messenger RNA (attached). Using this information, what sequence of nucleotides in the templ

Rashid [163]

Answer:

Explanation:

The correct answer would be option A - GUA-CAU-ACC

Looking at the table of codons, for the amino acid Val, the first base (which is on the 1st column in the 6th row) is G while the second base (2nd column, 2nd row) is U. The third column can be any of U, C, A, or G (6th column, 4th row). Hence, GUA is plausible

For the amino acid His, the first base is C (1st column, 2nd row), the second is A (4th column, 4th row) while the last could be any of the 4 bases. Hence, CAU is plausible.

For the amino acid Thr, the first base is A (first column, 5th row), the second is C (3rd column, 2nd row) while the 3rth could be any of the 4 nucleotide bases. Hence, ACC is plausible.

Therefore, the correct sequence of nucleotides for Val-His_Thr would be GUA-CAU-ACC
