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.
Assume 100 bair pair DNA double helix contains 45 cytosines. how many adenines are ther?
Since DNA base pairs always have an equal amount of adenine and thymine, if there are 45 cytosines, there would also be 45 guanines. Therefore, the number of adenines would be equal to the number of thymines, making it 100 - 45 - 45 = 10 adenines.
What are the 4 bases of the DNA ladder?
The four bases of the DNA ladder are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in a complementary way (A with T and C with G) to form the rungs of the DNA double helix.
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.
Abbreviation for the disease in which one of the enzymes needed to repair sunlight damsaged DNA is missing?
Ultra violet radiation from sunlight causes Pyrimidines in DNA to bind together in a way they aren't supposed to. This binding most often occurs between two thymines creating a thymine dimer. The dimer must be cut out of the DNA strand and replaced in a process called Nucleotide Excision Repair. In the disorder Xeroderma pigmentosum (abbreviated XP) one or more of the excision repair enzymes is missing leading to extreme sensitivity to sunlight and high likelihood of skin cancer.
What are the repeating units in DNA called?
Hydrogen Bonds Adenine, Thymines, Guaines, and Cytosines.
What are the four bases of making up the rungs of the DNA ladder?
thymines, guanines, adenines, and cytosines
What does photolyases do to thymine diamers?
Photolyases repair thymine dimers by using visible light energy to break the covalent bonds formed between adjacent thymine bases in the DNA strand. This process, called photoreactivation, restores the original structure of the DNA molecule by splitting the thymine dimer back into individual thymines.
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
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 type of physical mutagens produce tymine dimers?
Ultraviolet (UV) radiation is a type of physical mutagen that can produce thymine dimers. Thymine dimers are formed when adjacent thymines in the DNA strand become covalently linked, leading to DNA damage and potential mutations.
How many molecules of adenine and thymine are in each DNA model?
In DNA, adenine always pairs with thymine. Therefore, in each DNA model, the number of adenine molecules will be equal to the number of thymine molecules. The exact count of adenines and thymines will depend on the length of the DNA strand in the model.
How are nucleotides joined together within a single DNA strand?
I just did this paper in Biology, the answer is Hydrogen bonds! :)
Which RNA has thymine?
uracil but that's in rna its thymine in DNA
