deoxyguanosine

Thân thiện

A scientist examines a molecular model of deoxyguanosine in the lab.

Definition

1. Noun:
   • A nucleoside component of DNA: Deoxyguanosine is one of the four fundamental nucleoside building blocks that make up deoxyribonucleic acid (DNA). It is composed of the nucleobase guanine linked to the sugar deoxyribose.

Usage Examples

• Noun:
  • Deoxyguanosine pairs with deoxycytidine in the DNA double helix.
  • Scientists studied the role of deoxyguanosine in genetic coding.
  • A mutation can occur if deoxyguanosine is damaged or incorrectly paired.

Advanced Usage

• "Deoxyguanosine monophosphate (dGMP)": This refers to the phosphorylated form of deoxyguanosine, which is the actual nucleotide unit incorporated into a DNA strand.
  • The enzyme catalyzes the addition of deoxyguanosine monophosphate to the growing DNA chain.

Variants and Related Words

• Deoxyguanosine monophosphate (dGMP) (n): The nucleotide form, where deoxyguanosine has one phosphate group attached.
• Deoxyribonucleic acid (DNA) (n): The molecule that carries genetic instructions, composed of nucleotides including deoxyguanosine.
• Guanine (n): The purine nucleobase component of deoxyguanosine.
• Nucleoside (n): The class of molecules to which deoxyguanosine belongs, consisting of a nucleobase and a sugar.

Synonyms

• dG (abbreviation): A common shorthand for deoxyguanosine in biochemical contexts.
  • The sequence was analyzed for its dG content.

Related Phrases and Terms

• Base pair: In DNA, deoxyguanosine forms a specific base pair with deoxycytidine.
  • The stability of the DNA helix depends on correct base pairing, such as deoxyguanosine with deoxycytidine.
• DNA replication: The process where DNA is copied, requiring the incorporation of nucleotides like deoxyguanosine.
  • The polymerase enzyme ensures the correct insertion of deoxyguanosine during DNA replication.
