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 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 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).
How are cytosine and guanine related to each other?
Cytosine and guanine are two of the four nitrogenous bases found in DNA and RNA. They are complementary bases that form hydrogen bonds with each other, forming a base pair in the double helix structure of DNA. This complementary pairing is essential for the accurate replication and transmission of genetic information.
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.
How does a nitrogenous base pair with DNA?
In DNA, nitrogenous bases pair according to specific rules known as complementary base pairing. adenine(A) pairs with Thymine (T) and Cytosine(C) pairs with Guanine (G). This is due to the hydrogen bonds between these bases: two between A and T, and three between C and G. These pairings allow the double helix structure of DNA and enable the accurate replication of DNA during cell division.
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
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).
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.
What bases forms a true complementary pair?
cytosine and guanine
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 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
