What are the four bases of making up the rungs of the DNA ladder?
thymines, guanines, adenines, and cytosines
Assume 100 bair pair DNA double helix contains 45 cytosines. how many adenines are ther?
55. 45 cytosines would mean there must also be 45 guanines. This leaves room for 55 base pairs of adenine and thymine.
What are the 4 bases that make up the rung of the DNA ladder?
what are 4 bases that make up the rungs of the DNA ladder
What are adenines?
purines
How amny adenines are there?
4
How are nucleotides joined together within a single DNA strand?
I just did this paper in Biology, the answer is Hydrogen bonds! :)
What are the 4 bases of the DNA ladder?
Adenine,Thymine,Guanine,and Cytosine. Adenine and thymine pair up and guanine and cytosine pair up.
What are the middle rungs of the DNA ladder made of?
The rungs of the ladder are pairs of 4 types of nitrogen bases (thymines, adenines, guanines, cytosines).---The pairs are guanine and cytosine (G-C), or adenine and thymine (A-T).The rungs of the dna ladder are made of alternating sugars and phosophate groups.
What base in RNA compares with adenine?
Adenines base pair in RNA is uracil.
What are the repeating units in DNA called?
Hydrogen Bonds Adenine, Thymines, Guaines, and Cytosines.
Adenine bonds to what?
Adenine bonds with Thymine.Adenine complementary stand is Thymine in DNA but in RNA Thymine is replaced with Uracil. This means that Adenines complementary stand is Uracil in RNA.
Bacteria methylate their DNA in order to?
Protect their DNA from being excised by their own restriction enzymes such as EcoR1. The bacteria has enzymes that go through and methyl the N6 position of their adenines in order to prevent their own restriction enzymes from cutting their DNA up.
