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
What else can I help you with?
What best describes the correct pairs of DNA bases?
The correct pairs of DNA bases are adenine (A) with thymine (T), and cytosine (C) with guanine (G). This pairing is based on the complementary base pairing rule in DNA, where A always pairs with T and C always pairs with G.
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 is pair of complementary nitrogenous bases in DNA?
There are four nucleotides and each links to another specifically based on the number of hydrogen bonds it makes. A bonds with T (2 hydrogen bonds) and G links with C (3 bonds).
Is cytosine and thymine a true complementary pair?
Cytosine (C) and thymine (T) are not considered a true complementary pair in DNA. Instead, the true complementary pairs are adenine (A) with thymine (T) and cytosine (C) with guanine (G). This pairing is based on the hydrogen bonding properties of the nitrogenous bases, which ensure the stability of the DNA double helix. Thus, C and T do not pair with each other in the structure of DNA.
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 best describes the correct pairs of DNA bases?
The correct pairs of DNA bases are adenine (A) with thymine (T), and cytosine (C) with guanine (G). This pairing is based on the complementary base pairing rule in DNA, where A always pairs with T and C always pairs with G.
What is the pair of nitrogenous bases in a DNA molecule?
AT and GC

This pairing is based on the hydrogen bonding properties of the nitrogenous bases, which ensure the stability of the DNA double helix. Thus, C and T do not pair with each other in the structure of DNA.
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.
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 bases forms a true complementary pair?
cytosine and guanine
What belong to the class of nitrogenous bases called pyrimidines?
The pyrimidines are a class of nitrogenous bases that includes cytosine, thymine, and uracil. These bases are found in nucleic acids like DNA and RNA, where they pair with complementary purines to form the building blocks of genetic information.
How many nitrogenous bases are found in a anticodon?
3. The opposite three that are located on the codon of an mRNA strand.eg.If mRNA reads CAG UCG AGU Three codonsThen tRNA GUC AGC UCA Three Antiocodons each containing three nitrogenous bases.
How do the bases pair from mRNA (codon) to tRNA (anticodon) during the process of translation?
During translation, the bases in mRNA (codon) pair with complementary bases in tRNA (anticodon) through hydrogen bonding. This pairing ensures that the correct amino acid is added to the growing protein chain.
What links a pair of complementary bases together?
phospo-di-ester bond
