The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
Yes, all living organisms share the same four nucleotides that make up DNA: adenine, thymine, cytosine, and guanine. The unique arrangement and quantity of these nucleotides in an organism's DNA are what determine its genetic characteristics and differences from other organisms. These variations in DNA sequence and content contribute to the diversity seen among different species.
Uracil is only found in RNA nucleotides. In DNA uracil is replaced by thymine.

Chromosomes are DNA, which is made of sequences of nucleotides. Also there are some supporting factors such as proteint which help with it's structure and functioning. Nucleotides are molecules with a carbon-skeleton structure, about 3 small rings in size each. They bind in strings to other nucleotides quite strongly. One string binds less strongly to another string, but only if the nucleotides match (largely). In DNA there are four nucleotides, Adenine and Thymine which match, and Guanine and Cytosine which match.
All of the four nucleotides have a nitrogenous base. Adenine: has a double ring, nitrogenous base and found in DNA and RNA Thymine:single ring with nitrogenous base. ONLY FOUND IN RNA. not DNA. that is a difference from the rest of the three nucleotides. Cytosine: single ring with nitrogenous base, found in both DNA and RNA Guanine: double ring with nitrogenous base, found in DNA and RNA. also i guess you can say there is another difference with the double and single rings.

Living things exhibit vast diversity due to the unique combinations and sequences of the four nucleotides in their DNA. These nucleotides can be arranged in countless ways, leading to different genes and traits that contribute to the wide range of characteristics seen in living organisms.

Yes, nucleotides pair with specific complementary nucleotides based on their chemical properties.
DNA nucleotides. Note that adenine, thymine, cytosine and guanine are NOT nucleotides, but they are only the bases which make the nucleotides different.
Uracil is only found in RNA nucleotides. In DNA uracil is replaced by thymine.
Only one or two nucleotides are changed in a certain mutation. This is an example of a(n)
All nucleotides contain a phosphate group and a sugar molecule (ribose or deoxyribose), which form the backbone of the nucleotide. The nitrogenous base is the part that varies between nucleotides, with adenine, thymine, cytosine, and guanine being the four different bases found in DNA nucleotides. In RNA nucleotides, thymine is replaced by uracil.

The DNA molecule has four different kinds of nucleotides: adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides combine in specific sequences to form the genetic code that determines an organism's traits.
The four nucleotides found in DNA are adenine (A), thymine (T), cytosine (C), and guanine (G). These nucleotides form base pairs with each other, with adenine pairing with thymine and cytosine pairing with guanine. The sequence of these nucleotides along the DNA strand carries genetic information and determines the genetic code of an organism.
