The four types of nitrogenous bases are adenine (A), thymine (T), guanine (G), and cytosine (C). Adenine and guanine are purines, while thymine and cytosine are pyrimidines. Purines have a double-ring structure, while pyrimidines have a single-ring structure. This structural difference is important in how the bases pair with each other in DNA and RNA molecules.

Which nitrogenous base is composed of two rings?
the nitrogenous base which has double ring structure is purine.it consist two bases adenine and guanine;
What part of nucleotide contains the genetic code?
strand of DNA
How many types of hydrogen bond are found in a molecule of DNA?
There are two types of hydrogen bonds found in a molecule of DNA: adenine-thymine and cytosine-guanine base pairs. These hydrogen bonds are responsible for the complementary pairing of the nitrogenous bases in DNA strands.
What types of bond connects the nitrogenous bases?
The nitrogenous bases in DNA are connected by hydrogen bonds. Specifically, adenine pairs with thymine through two hydrogen bonds, while cytosine pairs with guanine through three hydrogen bonds. These hydrogen bonds are crucial for maintaining the structure of the DNA double helix and ensuring the stability of base pairing.
What rungs of DNA ladder made up of?
The rungs of DNA are made up of the nitrogenous bases Adenine (A), Cytosine (C), Guanine (G) and Thymine (T). Each rung represents the bonding of two bases (one from each DNA strand). A binds with T and C binds with G.
What are three types of pyrimidines?
Cytosine and thymine are the nitrogenous bases used in DNA. Uracil substitutes for thymine in RNA.
What four nitrogenous bases does DNA contain?
The four nitrogenous bases in in DNA are adenine, thymine, cytosine, and guanine.

The four types of nucleotides that make up DNA are named for their?
The four types of nucleotides that make up DNA are named for their nitrogenous bases: adenine (A), thymine (T), guanine (G), and cytosine (C). Each nucleotide consists of a phosphate group, a sugar molecule (deoxyribose in DNA), and one of these four nitrogenous bases.
What part of nucleotide contains the genetic code?
strand of DNA

Is DNA positively charged?
Deoxyribonucleic acid (DNA) is negatively charged, and comprises of a pentose sugar, a nitrogenous base and phosphate. The four types of nitrogenous bases are adenine (A), thymine (T), guanine (G), adenine (A), and cytosine (C).
Nitrogen bases made up of two rings are called?
Purines. They are one of the two types of nitrogenous bases found in DNA and RNA, and they consist of a double-ring structure. Adenine and guanine are examples of purines.

What does bases have to do with DNA?
DNA is a polynucleotide, made up of nucleotides. It has a phosphate-sugar backbone. (The sugar is deoxyribose). And, 'internal' are nitrogenous bases that are strung together (by hydrogen bonds) to complementary nitrogenous bases forming something like the rungs of a ladder. The DNA molecule is wound into a double helix. There are 4 types of the bases, adenine, cytosine, guanine and thymine, abbreviated A, C, G and T. A triplet of bases 'codes' for a single amino acid. Thus a whole string of triplets codes for a sequence of amino acids, a polypeptide. A gene is defined as the code for a single polypeptide. Thus, these bases have a lot to do with DNA.
What are the parts of a nitrogenous base?
A nitrogenous (nitrogen-containing) base is a nitrogen-containing molecule having the chemical properties of a base. It is an organic compound that owes its property as a baseto the lone pair of electrons of a nitrogen atom. In biological sciences, nitrogenous bases are typically classified as the derivatives of two parent compounds, pyrimidine and purine.They are non-polar and due to their aromaticity, planar. Both pyrimidines and purines resemble pyridine and are thus weak bases and relatively unreactive towards electrophilic aromatic substitution. Their flat shape is particularly important when considering their roles in nucleic acids as nucleobases (building blocks of DNA and RNA): adenine, guanine,thymine, cytosine, and uracil. These nitrogenous bases hydrogen bond between opposing DNA strands to form the rungs of the "twisted ladder" or double helix of DNA or a biological catalyst that is found in the nucleotides. Adenine is always paired with Thymine, and Guanine is always paired with Cytosine.
