Which nitrogen base bonds with adenine?
Thymine will always bond with adenine, and guanine will always bind with cytosine.
What nitrogenous bases will tend to hydrogen bond with adenine in DNA?
guanine
Why does C always have to bond with G?
C always has to bond with G because of base pairing rules. Only between Cytosine and Guanine are there opportunities to form hydrogen bonds. This is why Adenine or Thymine cannot bond with Guanine and Cytosine.
What is the base pair of nitrogen bases in a DNA molecule?
In DNA the nitrogen bases are either purines or pyrimidines.Adenine (A) and guanine (G) are purines, and thymine (T) and cytosine (C) are pyrimidines.A pairs with T on the complementary strand, and G with C.In RNA, A pairs with U (uracil). U is specific for RNA, and T is found only in DNA.-------------If you have the same crossword puzzle homework as I do, the specific answer is:BASE PAIRS
What is the difference between a nucleoside and a nucleotide?
Nucleoside contains a sugar group and a base whereas phosphorylation of nucleosides by kinases ( addition of phosphate in the sugar's primary alchohol group) produces nucleotides.nucleoside = sugar +basenucleotide = sugar + base + phosphate
In DNA molecules nucleotides bond together according to the nitrogenous bases Which of the following correctly describes how nitrogenous bases bond together?
Purines bond to pyrimidines
Which nitrogen base bonds with adenine?
Thymine will always bond with adenine, and guanine will always bind with cytosine.
Is uracil a nitrogenous base?
Yes, the two nitrogen atoms in urcil function as hydrogen bond acceptors, so the molecule is basic.
What nitrogenous bases will tend to hydrogen bond with adenine in DNA?
guanine
Which pair of nitrogenous bases will form a bond in a DNA molecule?
Complementary nitrogen bases pair by means of hydrogen bonds. Refer to the related link below for an illustration.
What type of bonds hold the individual DNA bases together?
If the DNA nitrogenous bases (A&T, G&C) alone, its the Hydrogen bond. Phosphate-Sugar= phosphoester bond Sugar-Nitrogenous bases= Beta N-glycosidic bond Sugar-phosphate-sugar = phosphodiester bond
Why does C always have to bond with G?
C always has to bond with G because of base pairing rules. Only between Cytosine and Guanine are there opportunities to form hydrogen bonds. This is why Adenine or Thymine cannot bond with Guanine and Cytosine.
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.

What two nitrogenous bases can bond with a denine?
Sorry i don't really know. Ask someone from your family...
What type of bonds form between the nitrogenous bases of a DNA molecule?
A hydrogen bond--two between A and T and three between G and C.
