Nitrogen Base pairs

Front

What is the role of nitrogen bases in DNA?

Back

Nitrogen bases are the building blocks of DNA and RNA, encoding genetic information. They pair specifically (A with T, C with G) to form the rungs of the DNA ladder.

Front

What are the four nitrogen bases found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What nitrogen base is found in RNA but not in DNA?

Back

Uracil (U) replaces Thymine (T) in RNA.

Front

What is the complementary base pair for Adenine in DNA?

Back

Thymine (T) pairs with Adenine (A).

Front

What is the complementary base pair for Cytosine in DNA?

Back

Guanine (G) pairs with Cytosine (C).

Front

How is mRNA synthesized from DNA?

Back

During transcription, the DNA sequence is copied into mRNA, where adenine pairs with uracil instead of thymine.

Front

What is the process of translating mRNA into a protein called?

Back

Translation.

Front

What is the significance of the codon AUG in mRNA?

Back

AUG is the start codon that signals the beginning of protein synthesis and codes for the amino acid Methionine.

Front

How many amino acids are there in the genetic code?

Back

There are 20 standard amino acids.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
