When DNA is extracted from E coli cells and analyzed for base composition it is found that 42 percent of the bases are cytosine this means that there is also 42 percent of which base?

If 42 percent of the bases in E. coli DNA are cytosine, then 42 percent will also be guanine. This is because cytosine always pairs with guanine through three hydrogen bonds in DNA double helix structure.


What are fats with double bonds are said to be?

What is the conclusion for the double color flower?

The double color flower exhibits a unique genetic trait that results in the production of petals with two distinct colors. This characteristic adds visual interest and beauty to the flower, making it a popular choice for ornamental purposes in gardens and floral arrangements.


What is the percent of cytosine in a DNA?

Double Stranded DNA is paired, with Adenine paired with Thymine Cytosine paired with Guanine Then the percent Cytosine in one strand will be exactly the percent Guanine in the other strand. And between the two strands, the percent Cytosine will be equal to the percent Guanine. For a random distribution, the percent should be about 25% for each nucleotide, or 50% for the GC pair, and 50% for the AT pair. However, DNA actually varies considerably from organism to organism. Streptomyces coelicolor A3(2), has a GC content as high as 72% Plasmodium falciparum has a GC content as low as 20%. See Wikipedia link on GC Content.


What is true about a circular double-stranded DNA genome that is determined by chemical means to be 21 percent adenosine?

If a circular double-stranded DNA genome is determined to be 21% adenosine by chemical means, it means that the amount of thymine will also be 21%. This is because in DNA, adenine always pairs with thymine. Consequently, the total percentage of adenine and thymine in the DNA will be 42%.

Does Interest Compounded semi-annually double every year?

No.


How many years will it take for an investment to double if the interest rate is 8 percent per year compounded annually?

11 years


Is it true that it will take money in savings 14.2 years to double at 5 percent interest compounded annually?

Yes, that's an accurate number.


How long would it take 100 to double 5 percent?

As a rough guide to double any amount compounded annually, divide 70 by the interest rate. In this case that is 14 years.


In how many years your amount will be double if rate of interest is 10 percent annually in compound interest?

Approximately 7 years. The general rule is to divide 70 by the interest rate to get an approximation of how long it will take to double. If the interest is compounded annual you will have $194.88 after 7 years, and $214.37 after 8 years. Though if interest is compounded more regularly (ie. monthly or daily) this will grow at a slightly faster rate.


How long does an investment earning 9 percent take to double in value?

8.0432 years (rounded) if compounded annually.


How long will money in savings take to double at 5 percent interest compounded annually?

Use the "rule of 72"...simply put, using compound interest you take the number 72 and divide it by the interest rate. Thus, at 5% the time to double is 14.4 years. This formula can be used for calculating a "double" for any interest rate using the same mathematical procedure.

What rate of interest compounded annually is required to double an investment in 21 years?

(2)1/21 = 1.03356 (rounded)That's an annual interest of 3.356 percent.Let's try it:(1.03356)21 = 2.00009 on my calculator, which is pretty close.


How many years does it take your money to double if it earns 1 percent per year?

Approx 69.661 years if the interest is compounded. 100 years otherwise.


What interest rate is required for an investment with continuously compounded interest to double in 8 years?

It is approx 8.66%


Show steps to solving 8000 invested for 7 years at 8 percent compounded annually?

The basic equation for compounded interest is: FV=PV(1+i)^nt FV=future value PV=present value i=interest compounded per term n=number of times compounded per year t=number of years For this situation: FV=? PV=8000 i=.08 n=1 t=7 Plugging the numbers into the equations gives you FV=8000(1+.08)^7 Solving gives you the amount of 13710.59 A way to roughly check your answer is to use the rule of 72. The rule of 72 is a method of seeing how long it would take to double ones money at a certain interest percent. The interest is 8% so divide 72 by 8 and you get 9. So at 8 percent it would take about 9 years to double your money. Since we only had 7 years, it makes sense that we did not double our money, but we fairly close to doing so, meaning that our answer is viable. This is only a way to roughly check the answer.
