What are the 3 parts of a nucleotide?
Phosphate group
Pentose sugar
Nitrogenous base
How does the structure of DNA contribute to its function?
The double helix allows for stable base pairing
What is the function of the nitrogenous base in a nucleotide?
The nitrogenous base (such as adenine, guanine, cytosine, or thymine) carries the genetic information and allows base pairing between DNA strands.
How does the structure of DNA differ from RNA?
DNA has a deoxyribose sugar, while RNA has a ribose sugar
What type of sugar is present in a nucleotide?
Pentose sugar
If the nitrogenous base in a nucleotide is adenine, what is the complementary base it will pair with?
Thymine
How do the three parts of a nucleotide (phosphate group, pentose sugar, and nitrogenous base) work together to form the structure of DNA and RNA?
The phosphate group provides the negative charge to link nucleotides, the pentose sugar forms the backbone, and the nitrogenous bases allow base pairing between strands
Which base pairs with Cytosine (C) in DNA?
Guanine (G)
What is the role of the phosphate group in a nucleotide?
It connects to the sugar via a phosphodiester bond
What are the three main components of a nucleotide?
Phosphate group, pentose sugar, nitrogenous base
What type of bond connects the phosphate group to the sugar in a nucleotide?
Phosphodiester bond
Where does the nitrogenous base attach in a nucleotide?
To the sugar's first carbon atom
What is the name of the nitrogenous base that replaces Thymine in RNA?
Uracil
What are the four nitrogenous bases that make up DNA?
Adenine, Thymine, Cytosine, Guanine
How do the nitrogenous bases in DNA form base pairs?
Adenine (A) pairs with Thymine (T)
Cytosine (C) pairs with Guanine (G)
These base pairs are held together by hydrogen bonds
What group is present in each DNA nucleotide?
Phosphate group
What are the structural components of a DNA nucleotide?
Sugar (deoxyribose)
Phosphate group
Nitrogenous base (A, T, C, G)
How does the structure of DNA allow it to store and transmit genetic information?
The double helix structure of DNA
Complementary base pairing (A-T, C-G)
Ability to replicate and pass on genetic information
What is the structure of DNA?
Double helix
How do the RNA and DNA Nucleotides differ in the image?
RNA uses Ribose, DNA uses Deoxyribose
