The four different nucleotides have different strucutres: Adenine and Guanine have 2 ring structures. However, Cytosine and Thymine have singular ring structures. This means that Adenine cannot pair with Guanine as the two ring structures will be bigger than the singular ringed structure and the two strands of DNA are equidistant the entire length. Adenine and Thymine both have the ability to form 2 hydrogen bonds, whereas Cytosine and Guanine form 3 hydrogen bonds. Therefore Adenine and Thymine bond together, Cytosine and Guanine bond together. These hydrogen bonds between four different types of nucleotides (due to 4 different nitrogenous bases) hold together the two strands of DNA to form a double strand of DNA.

How do dna bases pair up with mrna bases?
The mRNA bases are complementary to the DNA bases, and so form H-bonds when the DNA is single-stranded. DNA - mRNA A - U T - A C - G G - C
Which bases pair together in human DNA?
Adenine pair up with thymine. guanine pair up with cytosin
What shows how bases pair in complementary strands of DNA?
A-T and C-G
What does the structure of DNA contain?
DNA contains 4 nitrogenous bases that pair with each other. Thymine always pairs with Adenine, and Cytosine always bonds with Guanine. DNA also contains the sugar deoxyribose.
What are the 4 bases the make up the rungs of the DNA ladder?
what are 4 bases that make up the rungs of the DNA ladder
How many different nitrogenous bases exist and are found in Dna?
There are only 4 nitrogenous bases in DNA. These are adenine, thymine, guanine, and cytosine. Adenine will only pair with thymine, and guanine will only pair with cytosine.
Describe how each of the DNA nitrogen bases together in DNA?
Describe how each of the DNA nitrogen bases pair together
What are the 4 DNA nitrogen bases pairing rules?
The 4 Nitrogen Bases are Adenine, Guanine, Cytosine and Thymine
What is the pair of nitrogenous bases in a DNA molecule?
AT and GC
A pair of these form a rung in the DNA ladder?
A pair of the 4 nitrogen bases represented by an a, t, c, or g
How do dna bases pair up with mrna bases?
The mRNA bases are complementary to the DNA bases, and so form H-bonds when the DNA is single-stranded. DNA - mRNA A - U T - A C - G G - C
Which bases pair together in human DNA?
Adenine pair up with thymine. guanine pair up with cytosin
Copy and complete the events chain concept map of DNA synthesis?
step1: enzyme separates DNA sides. step2: new bases pair with bases on original DNA. step3: two new identical DNA molecules are produced.
What arrangement of two bases in the DNA molecule forms?
Base Pair
How the nitrogen bases pair in a DNA molecules?
The order of the bases in each new DNA molecule exactly matches the order in the original DNA molecule by bringing them together with the original DNA cells.
Does dna and RNA have nitrogenous bases?
Both DNA and RNA have nitrogenous bases. The nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). The nitrogenous bases in RNA are adenine (A), uracil (U), cytosine (C), and guanine (G). In DNA, A and T pair together, as does C and G. In RNA, C and G also pair together, but A pairs with U because U replaces T in RNA.
How many bases are in DNA and what are the names of the bases?
There are 4 bases in DNA: adenine, thymine, cytosine, and guanine.
