Answer:

DNA is present as genetic material in all the living organism except some virus. DNA structure follows the Chargaff's rule in which states that the ratio of pyrimidines to purines is equal to 1.

So, amount of adenine will be equal to thymine. If adenine is 30% then thymine is also 30%. Total amount of DNA is 100%. Cytosine and thymine are also equal in the DNA molecule. The total amount of cytosine and guanine is 40%. The amount of cytosine is 20% and the amount of guanine is also 20%.

Thus, thymine is 30%, cytosine is 20% and guanine is 20%.

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the
gregori [183]

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59
