Which letters go together in DNA?
Thymine - represented by letter (T) Adenine - represented by letter (A) Guanine represented by letter (G) Cytosine represented by letter (C) So the letters of dna are TAGC
What are the 4 RNA nucletides?
Adenine, Guanine, Cytosine, and Uricil RNA uses three of the same nucleotides that DNA uses:two purines, called adenine (A) and guanine (G), and the pyrimidine cytosine(C).However RNA uses Uracil where DNA uses Thymine.Thus the four RNA nucleotides are Adenine, Guanine, Cytosine, and Uracil
Why would a DNA molecule have the same percentage of guanine and cytosine in it?
A DNA molecule may have the same percentage of guanine and cytosine because they bond together through three hydrogen bonds, forming a stable base pair. This complementary pairing ensures that the total percentage of guanine always equals the total percentage of cytosine in a DNA molecule, known as Chargaff's rule.
Explain how chargaff's helped watson and crick model dna?
Chargaff discovered that in DNA the percentages of adenine and thymine were the same, and the percentages of cytosine and guanine are the same. This led to the idea of base-pairing between adenine and thymine, and cytosine and guanine.
What four bases are in DNA?
G A T C easy way to remember? Just think of the movie GATACA
What are the four base of rna?
RNA contains four different bases, three of which are the same as in DNA: adenine, guanine, and cytosine. The other one is uracil (U).
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.*
What are all the bases of RNA?
In DNA, there are four different bases: adenine (A) and guanine (G) are the larger purines. Cytosine (C) and thymine (T) are the smaller pyrimidines. RNA also contains four different bases. Three of these are the same as in DNA: adenine, guanine, and cytosine.
If DNA were 40 percent cytosine what would be percent of guanine?
20% because cytosine and guanine have equal amounts. Always
Which bases does Guanine always bond with to form a pair in DNA?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
What base always base pairs with guanine?
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
Does DNA consists of five different nucleotides and does RNA consists of four different nucleotides?
No, first of in total, both RNA and DNA combined have five nucleotides, DNA and RNA, both consists of three of the same nucleotides, and have one that varies between the two. Both DNA and RNA, have the nucleotides, guanine, cytosine and adenine, however DNA, has the additional nucleotide thymine and RNA instead of thymine has uracil. So, DNA's nucleotides are guanine, cytosine, adenine and thymine, while RNA's are guanine, cytosine, adenine and uracil. To specifically answer the question, no DNA consists of four different nucleotides and RNA consists of three of the same nucleotides, with one differing.
What is the part of the nucleotide that differs among the other different nucleotides?
All nucleotides are similar except for the nitrogen bases, which may either be adenine, cytosine, guanine, thymine, or uracil..
Do DNA and RNA have the same nitrogenous bases?
No, DNA and RNA do not have the same nitrogenous bases. DNA contains adenine (A), thymine (T), cytosine (C), and guanine (G), while RNA contains adenine (A), uracil (U), cytosine (C), and guanine (G).
If there are 45 cytosines and 55 thymines how many guanines are there?
Given that DNA base pairing rules state that cytosine pairs with guanine and adenine pairs with thymine, for every cytosine there must be one guanine. Therefore, if there are 45 cytosines, there must also be 45 guanines.
Which letters go together in DNA?
Thymine - represented by letter (T) Adenine - represented by letter (A) Guanine represented by letter (G) Cytosine represented by letter (C) So the letters of dna are TAGC
What scientist discovered that there is the same amount of cytosine and guanine?
Erwin Chargaff discovered that in DNA, the amount of cytosine is equal to the amount of guanine. This observation forms part of Chargaff's rules, which laid the foundation for understanding DNA base pairing.
