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 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.
Why is it very needful to have a correct pair of nitrogenous bases?
Having the correct pair of nitrogenous bases is essential for accurate DNA replication and protein synthesis. Base pairing ensures that the genetic code is preserved during cell division, preventing mutations that could lead to diseases. Additionally, proper base pairing allows for the formation of stable double helices, which is crucial for the structural integrity of DNA. Ultimately, accurate base pairing underpins the fidelity of genetic information transfer across generations.
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
What is the attraction between nitrogenous bases?
The attraction between nitrogenous bases is due to hydrogen bonding. This bonding occurs between specific pairs of bases in DNA (adenine-thymine, guanine-cytosine) and RNA (adenine-uracil, guanine-cytosine), contributing to the stability of the double helix structure.
What are the nitrogenous bases in DNA and how do you know whether there are two bonds or three?
The four nitrogenous bases in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). In DNA, adenine pairs with thymine with two hydrogen bonds, and cytosine pairs with guanine with three hydrogen bonds. This pairing is based on the structure and chemical properties of the bases, which allow for complementary base pairing.
What are the ladders of DNA made of?
The 'steps' on the 'DNA Ladder' are made up of the four nitrogenous bases, Cytosine, Guanine, Thymine, and Adenine, while the pairing bases (Adenine & Thymine, Cytosine & Guanine) are bonded together with a hydrogen bond. The pairing bases (the 'rungs' of the ladder) are connected to the side posts of the ladder, which contain phosphate.
What structural feature helps DNA replicate?
complementary pairing of nitrogenous bases
Can the DNA molecule be compared to a ladder?
Yes, the DNA molecule can be compared to a ladder, where the two long strands represent the sides of the ladder, and the rungs are formed by pairs of nitrogenous bases that connect the strands. This ladder-like structure is known as the double helix. The specific pairing of the bases (adenine with thymine and cytosine with guanine) ensures the integrity of genetic information, much like how rungs maintain the structure of a ladder.
What is pairing arrangement of nitrogenous bases?
Adenine pairs with thymine, and cytosine pairs with guanine.

The secret of DNA has to do with the sequence of what along the DNA ladder?
The sequence of the nitrogenous bases, which are the 'rungs' of the DNA 'ladder' are what give DNA its specificity.
What parts of the nucleotides make up the rungs of the ladder?
In DNA, the actual nitrogenous base rings make up the "ladder" while the "sides" are made from alternating deoxyribose and phosphate groups.
What the correct pairing of DNA bases?
A with T, and C with G.
Four kinds of nitrogenous base?
The four nitrogenous bases found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These bases pair up in specific combinations to form the "rungs" of the DNA double helix, with adenine pairing with thymine and cytosine pairing with guanine.
