Adenine binds to thymine with 2 hydrogen bonds, and cytosine binds to guanine with 3 hydrogen bonds. In RNA thymine is replaced with uracil. A and G are purines, whereas C, T and U are pyrimidines.

What is the base pairing rule in DNA?

Adenine pairs with thymine Guanine pairs with cytosine.


What is the base pair rule for DNA?

In DNA the base pairs are Adenine with Thymine and Guanine with Cytosine. In RNA Thymine is replaced by Uracil so the base pairs are Adenine with Uracil and Guanine with Cytosine.


When purine base only pairs with a pyrimidine?

This is a basic principle of DNA base pairing called Chargaff's rule. Adenine (purine) pairs with thymine (pyrimidine), while guanine (purine) pairs with cytosine (pyrimidine). This complementary base pairing is essential for the double-stranded structure of DNA.


A base represented by A always combines with?

a base represented by T due to complementary base pairing in DNA. This is known as Chargaff's rule, where adenine (A) pairs with thymine (T) and cytosine (C) pairs with guanine (G).


What are base pairs in biotechnology?

In biotechnology, base pairs refer to the complementary pairing of nitrogenous bases in DNA molecules. Adenine pairs with thymine, and guanine pairs with cytosine. Understanding base pairs is crucial for techniques like PCR and DNA sequencing.


Why can you predict the base of one strand in a molecule of DNA if you know the sequence of the other strands?

in DNA, each base pairs up with only one other base


What are the base pairs that are found in DNA?

The base pairs found in DNA are adenine with thymine, and cytosine with guanine.


How are DNA bases always paired?

DNA bases are always paired through hydrogen bonding. Adenine pairs with thymine, while cytosine pairs with guanine. This complementary base pairing ensures the stability and accuracy of DNA replication and transcription processes.


What rule is used to join the free nucleotides to the exposed bases of the DNA?

The rule used to join free nucleotides to the exposed bases of DNA is base pairing. Adenine pairs with thymine, and guanine pairs with cytosine through hydrogen bonding. This complementary base pairing ensures the accurate replication of DNA during cell division.


Is DNA always six base pairs long?

No, DNA is not always six base pairs long. The length of DNA can vary and is determined by the number of nucleotide base pairs present in the DNA molecule. The human genome, for example, consists of about 3 billion base pairs.


Which mrna base always pairs with what DNA base?

In the base pairing between mRNA and DNA, the mRNA base adenine (A) pairs with the DNA base thymine (T). Conversely, uracil (U) in mRNA pairs with adenine (A) in DNA, as uracil replaces thymine in RNA. Cytosine (C) pairs with guanine (G) in both DNA and mRNA, and guanine (G) pairs with cytosine (C).


Which base pairs with adenine in DNA?

In DNA the base pairs are Adenine with Thymine and Guanine with Cytosine. In RNA Thymine is replaced by Uracil so the base pairs are Adenine with Uracil and Guanine with Cytosine.
