DNA has a deoxyribose sugar; RNA has a ribose sugar
DNA is a double stranded helix; RNA is a single stranded helix
RNA has the nitrogen base uracil instead of thymine (thymine is one of the four bases in DNA).
The main difference between the four nucleotides that make up DNA is in their nitrogenous bases. Adenine pairs with thymine, and cytosine pairs with guanine. These base pairs are complementary and form the double helix structure of DNA.
The main difference is that DNA contains deoxyribose sugar, while RNA contains ribose sugar. This difference in sugar composition affects the structure and function of each molecule.
the difference is that DNA is a double helix and RNA is a single chain
No oxygen on the second carbon of the deoxyribose sugar used in DNA. That is the only difference between ribose and deoxyribose sugars. And, of course RNA is single stranded and has catalytic properties DNA does not have. DNA is strictly a storage of information molecule.
In molecular biology, the main difference between ddNTPs and dNTPs is that ddNTPs lack a 3' hydroxyl group, which prevents further DNA strand elongation when they are incorporated into a DNA strand during sequencing. This makes ddNTPs useful for determining the sequence of a DNA fragment, while dNTPs are used for DNA replication and synthesis.
Chromatins are made up of DNA strands
There are three main differences between RNA and DNA: The sugar in RNA is ribose instead of deoxyribose, RNA is generally single-stranded, and RNA contains uracil in place of thymine.
DNA contains the sugar deoxyribose and RNA contains the sugar ribose. Deoxyribose sugar has one less oxygen atom than ribose.
No, there is no difference in appearance between DNA from different cells. DNA is a molecule that has a uniform structure regardless of the cell type it is found in. The only differences in DNA between cells come from variations in the sequence of nucleotides that make up the DNA.
The main difference is that DNA contains deoxyribose sugar, while RNA contains ribose sugar. Deoxyribose has one less oxygen atom than ribose, which affects the stability and function of the molecules.
The main difference in shape between DNA and RNA lies in their sugar molecules. DNA contains deoxyribose sugar, which lacks an oxygen atom on the 2' carbon, resulting in a double-stranded helical structure. RNA, on the other hand, contains ribose sugar with the oxygen atom, giving it a single-stranded structure that can fold into various shapes.
The three main structural differences between DNA and RNA are: DNA is double-stranded, while RNA is single-stranded. DNA contains the sugar deoxyribose, while RNA contains the sugar ribose. DNA contains the base thymine, while RNA contains the base uracil instead.
