Is cytosine not a nucleotide of DNA?
Cytosine is a nitrogenous base that is a component of DNA, but on its own, it is not a nucleotide. In DNA, cytosine pairs with guanine through hydrogen bonding to form a complementary base pair. Nucleotides are composed of a nitrogenous base, a sugar, and a phosphate group.
What is the correct pairing of the nitrogenous bases of the rungs of the DNA ladder?
In the DNA ladder structure, the nitrogenous bases pair specifically as adenine (A) with thymine (T) and cytosine (C) with guanine (G). This complementary pairing is crucial for the stability of the DNA double helix and is governed by hydrogen bonding, with A forming two hydrogen bonds with T and C forming three hydrogen bonds with G.
What part of the DNA ladder connects to phosphate?
In the DNA ladder structure, the phosphate groups connect to the deoxyribose sugar molecules, forming the backbone of the DNA strand. Each deoxyribose sugar is linked to a phosphate group, creating a repeating sugar-phosphate backbone that supports the nitrogenous bases. The nitrogenous bases, which include adenine, thymine, cytosine, and guanine, extend from the sugars and pair with complementary bases on the opposite strand.
What are the correct pair of complementary nitrogenous bases in DNA?
In DNA (Deoxtribonucleic acid) there are 4 bases and the pairning rules are as follows: Adenine-Thymine and the other is Guanine-Cytosine However in RNA (Ribonucleic Acid) the bases are different and thus the base pairing-the "complimentary pairs" are Adenine-Uracil and Guanine-Cytosine
Which molecules make up the horizontal rungs of a DNA ladder?
The horizontal rungs of a DNA ladder are composed of nucleotide pairs. Each nucleotide pair consists of a nitrogenous base (adenine, thymine, cytosine, or guanine) attached to a deoxyribose sugar molecule, which is in turn connected to a phosphate group. The nitrogenous bases form specific hydrogen bonds with their complementary bases on the opposite strand, creating the double helix structure of DNA.
What is the pair of nitrogenous bases in a DNA molecule?
AT and GC
What structural feature helps DNA replicate?
complementary pairing of nitrogenous bases
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.
What is meant by nitrogenous base pairs?
The pair of nitrogenous bases that connects the complementary strands of DNA or of double-stranded RNA and consists of a purine linked by hydrogen bonds to a pyrimidine: adenine-thymine and guanine-cytosine in DNA, and adenine-uracil and guanine-cytosine in RNA.
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.
Does DNA replication use thymine?
I guess yes. Guanine, Adenine, Cytosine and Thymine are the nitrogenous bases for DNA, So when it replicates It should use T to complementary-pairs to A.
Is cytosine not a nucleotide of DNA?
Cytosine is a nitrogenous base that is a component of DNA, but on its own, it is not a nucleotide. In DNA, cytosine pairs with guanine through hydrogen bonding to form a complementary base pair. Nucleotides are composed of a nitrogenous base, a sugar, and a phosphate group.
What part of the DNA ladder connects to phosphate?
In the DNA ladder structure, the phosphate groups connect to the deoxyribose sugar molecules, forming the backbone of the DNA strand. Each deoxyribose sugar is linked to a phosphate group, creating a repeating sugar-phosphate backbone that supports the nitrogenous bases. The nitrogenous bases, which include adenine, thymine, cytosine, and guanine, extend from the sugars and pair with complementary bases on the opposite strand.

The two strands of DNA molecules are held together by?
hydrogen bonds between complementary nitrogenous bases.
What four nitrogenous bases does DNA contain?
The four nitrogenous bases in in DNA are adenine, thymine, cytosine, and guanine.
Which molecules make up the horizontal rungs of a DNA ladder?
The horizontal rungs of a DNA ladder are composed of nucleotide pairs. Each nucleotide pair consists of a nitrogenous base (adenine, thymine, cytosine, or guanine) attached to a deoxyribose sugar molecule, which is in turn connected to a phosphate group. The nitrogenous bases form specific hydrogen bonds with their complementary bases on the opposite strand, creating the double helix structure of DNA.
