How many spirals does a DNA molecule have?
Nucleic acids are made up of chains of many repeating units called nucleotides (see bottom left of Figure 1 below). The DNA molecule actually consists of two such chains that spiral around an imaginary axis to form a double helix (spiral.)
What percentage would make up cytosine if guanine makes 31 of the nucleotide sample of DNA?
Correct answer: Together, adenine and thymine compose 70\% of the segment. This means that 30\% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15\% of the DNA section will be cytosine bases.
How many turns of double helix of DNA will be there in a molecule of DNA having 45 base pairs?
So, the correct answer to the given question is option A, i.e., DNA will take 4500 turns if it consists of 45000 base pairs.
How many spirals A DNA of 2000 base pairs have?

What percent of the DNA strand is cytosine *?
In this example cytosine makes up 42\%, which means that guanine also makes up 42\%. So 84\% of the DNA is a G-C base pair.
How many full turns of the DNA helix are there in this molecule?
The DNA double helix. (A) A space-filling model of 1.5 turns of the DNA double helix. Each turn of DNA is made up of 10.4 nucleotide pairs and the center-to-center distance between adjacent nucleotide pairs is 3.4 nm. The coiling of the two strands around (more…)
How many turns in a DNA helix?
The double helix makes one complete turn about its axis every 10.4–10.5 base pairs in solution.
How many adenine and cytosine are in DNA DNA?
DNA forms a two-stranded spiral, or double helix. Note that adenine always bonds with thymine and cytosine always bonds with guanine. Since you have 35 C, you will have 35 G. Without knowing the number of thymine, the number of adenine is unknown .
How many cytosine bases will a double-stranded DNA molecule of 50 base pairs contain?
A double-stranded DNA molecule of 50 base pairs contains 15 cytosine bases (C), how many thymine bases will it have? How many base pairs per turn of the helix would MOST likely correspond to a relaxed DNA molecule? The following table shows Chargaff’s data that demonstrates base composition of DNA from different biological sources. (6)
What is the content of adenine in a single stranded DNA sample?
In the question, the DNA sample referred is a single stranded DNA. 4. In DNA, guanine is 10\%. The content of adenine is If guanine=10\% as guanine will always pair with cytosine, i.e.cytosine is also 10\% then adenine and thymine accounts 80\% as adenine will always pair with thymine.
What is 20\% adenine and 20\% thymine?
You have 20\% of adenine. If you have 20\% of adenine than you have 20\% of thymine, because the amount of adenine and thymine is equal. 20\% plus 20\% is 40\% of adennine and thymine. From 100\% DNA bases subtract 40\% and you will get 60\%.
