Which rna base bonds with cytosine
Which RNA base bonds with cytosine quizlet?
either of the nucleotide bases linked by a hydrogen bond on opposite strands of DNA or double-stranded RNA: guanine is the complementary base of cytosine, and adenine is the complementary base of thymine in DNA and of uracil in RNA. You just studied 11 terms!
Which bases pairs with cytosine?
guanine
In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
Which RNA base bonds with?
Explanation: Base pairs occur when nitrogenous bases make hydrogen bonds with each other. Each base has a specific partner: guanine with cytosine, adenine with thymine (in DNA) or adenine with uracil (in RNA).
Which RNA base bonds with adenine?
Explanation: Uracil in RNA bonds to adenine on the DNA template during transcription. These two nitrogenous bases form two hydrogen bonds.
Which nitrogen base is complementary to cytosine?
guanineDeoxyribonucleic acid (DNA), the hereditary material of most living organisms, consists of the five-carbon sugar deoxyribose with a phosphate linkage, to which is attached cytosine or any of three other bases, which together form two complementary pairs. Cytosine’s complementary base in the DNA molecule is guanine.
Why does guanine pair with cytosine?
Guanine and cytosine make up a nitrogenous base pair because their available hydrogen bond donors and hydrogen bond acceptors pair with each other in space. Guanine and cytosine are said to be complementary to each other.
Which RNA base bonds with adenine which RNA base bonds with cytosine which RNA base bonds with guanine?
In RNA adenine binds to uracil and cytosine binds to guanine.
What nitrogenous base does cytosine C bond with in DNA?
Guanine
Explanation: In a DNA molecule, Adenine pairs with Thymine by two hydrogen bonds and Cytosine pairs with Guanine by 3 hydrogen bonds.
Which nitrogen base most closely resembles cytosine and why?
Which nitrogen base most closely resembles cytosine and why? Thymine because they are both pyrimidines.
What type of bases are cytosine and thymine?
pyrimidines
Cytosine and thymine are pyrimidines which are structures composed of a single six-sided ring. Adenine always binds to thymine, while cytosine and guanine always bind to one another. This relationship is called complementary base paring.
What is purine and pyrimidine bases?
Purines and pyrimidines are the nitrogen bases that hold DNA strands together through hydrogen bonds. … The purines in DNA are adenine and guanine, the same as in RNA. The pyrimidines in DNA are cytosine and thymine; in RNA, they are cytosine and uracil.
Which of the following are nitrogenous bases of the pyrimidine type?
The pyrimidine bases are thymine (5-methyl-2,4-dioxipyrimidine), cytosine (2-oxo-4-aminopyrimidine), and uracil (2,4-dioxoypyrimidine) (Fig. 6.2).
What is between guanine and cytosine?
Cytosine and guanine pairing can be found in both DNA and DNA-RNA hybrid formed during replication and transcription. The two nitrogenous bases are held together by three hydrogen bonds. … The second hydrogen bond is formed between N-3 of cytosine and Hydrogen atom attached to N-1 of guanine.
Which of the following is a complementary base pair for DNA adenine and cytosine guanine and cytosine adenine and guanine cytosine and thymine?
Explanation: The four nitrogenous bases of DNA are thymine, adenine, guanine, and cytosine. Guanine and cytosine are bound together by three hydrogen bonds; whereas, adenine and thymine are bound together by two hydrogen bonds. This is known as complementary base pairing.
What stops adenine from bonding with cytosine?
They both have to -OH/-NH groups which can form hydrogen bridges. When one pairs Adenine with Cytosine, the various groups are in each others way. For them to bond with each other would be chemically unfavorable.
Does guanine pair with cytosine?
Guanine is one of the building blocks of DNA. … Guanine in the double helix pairs with cytosine, so you will see CG pairs; one on one strand and one on the other.
Does cytosine pair with guanine in RNA?
Attached to each sugar is one of four bases–adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.
What are the base pairings of guanine and cytosine?
Guanine pairs with cytosine, and adenine pairs with thymine in DNA. Interstrand hydrogen bonds are responsible for this pairing.
