What are the 4 letters that make up the alphabet code 4 DNA?
a t c and g they represent adenine thymine cytosine and guanine
What number is equal to a opposite?
the number 0 is always equal to its opposite
Does 100 equal 100?
Yes. Every number is equal to itself (and to no other number).
What does greater than equal to mean?
This means that whatever a given number "a" is, number "b" is larger that number "a". If you are trying to say equal or greater, it would be number "b" is either equal to number "a", or of larger value than "a".
What is equal to 428?
428 is equal to 428. No other number is equal to 428.
The number of which base is equal to the number of guanine in a DNA molecule?
DNA contains four nucleic acid bases. These can be remembered by the acronym ACGT where the A stands for adenine, the C stands for cytosine, the G stands for guanine, and the T stands for thymine.
What two bases are in purines?
Adenine and guanine are the two purines bases present in DNA.Two purines in DNA are adenine and guanine.
What nucleotide basis are present in equal amounts of DNA?
In equal amounts, the nucleotide bases adenine (A) and thymine (T) are present, as well as guanine (G) and cytosine (C). This is because of the specific pairing arrangement that dictates A pairs with T and G pairs with C in DNA molecules.
What is correct about Chargaff's rule for each species A adenine equals guanine B adenine equals thymine C adenine equals cytosine D adenine guanine thymine and cytosine amounts are equal?
C adenine equals thymine. Chargaff's rule states that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.
How many Guanine's are in a DNA?
There is no consistent amount of guanine in everyone's DNA, but there is an equal amount of guanine and cytosine as well equal amounts of thymine and adenine.
According to chargaff's rules the percentages of what are equal to those of thymine?
According to Chargaff's rules, the percentage of adenine is equal to thymine in a double-stranded DNA molecule. These rules state that in DNA, the amount of adenine is equal to the amount of thymine, and the amount of guanine is equal to the amount of cytosine.
Which two nitrogenous bases are purines?
The two nitrogenous bases that are purines are adenine and guanine.
What forensic scientist is trying to find out the number of adenine in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine?
The forensic scientist can assume that the number of adenine molecules in the DNA sample is equal to the number of thymine molecules, as adenine always pairs with thymine in DNA. This is known as Chargaff's rule. By determining the number of thymine molecules, the scientist can indirectly infer the number of adenine molecules present in the DNA sample.
If adenine makes up 30 percent of the bases in a DNA helix what percentage of the bases are cystosine?
There are four bases in the DNA double helix: adenine, guanine, cytosine and thymine. An adenine in one strand always pairs with a thymine in the other strand. Similarly, a cytosine always pairs with a guanine. So the number of adenines always equals the number of thymines, and the number of cytosines always equals the number of thymines. The total number of bases must equal 100%. So if 30% of the bases are adenine, another 30% must be thymine because they always pair with each other. Thymine and adenine added together therefore make 60% of the bases. The remaining 40% must be cytosine plus guanine. If the number of cytosines must equal the number of guanines, the percentage of cytosines must be ....... well, you can work it out for yourself!
Name the four nitrogen bases?
There are 4 nitrogenous bases found in DNA; Cytosine, Adenine, Guanine, and Thymine. Cytosine pairs with Guanine, and Thymine pairs with Adenine. *In RNA, Uracil replaces Thymine, therefore Adenine pairs with Uracil, in RNA.*
If a species has 23 percent adenine in its DnA what is the percentage of guanine it would contain?
If a species has 23% adenine, we know that adenine pairs with thymine. In DNA, the amount of adenine is equal to the amount of thymine, so together they make up 46% (23% adenine + 23% thymine). This leaves 54% for guanine and cytosine, of which guanine would be 27%.
What are the 4 different bases in DNA?
The four different bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). They pair up in specific combinations (A-T and C-G) to form the double helix structure of DNA.
