Codon Chart

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or a stop signal during protein synthesis.

Front

What does the codon UUA represent?

Back

Leucine.

Front

What is the start codon in mRNA?

Back

AUG, which codes for Methionine.

Front

How is mRNA synthesized from DNA?

Back

During transcription, RNA polymerase reads the DNA template and synthesizes a complementary mRNA strand.

Front

What is the role of tRNA in translation?

Back

tRNA transports specific amino acids to the ribosome, matching its anticodon with the corresponding codon on the mRNA.

Front

What is the significance of the genetic code being universal?

Back

The genetic code is nearly the same in all organisms, indicating a common evolutionary origin and allowing for genetic engineering across species.

Front

What is the difference between a stop codon and a start codon?

Back

A start codon (AUG) signals the beginning of protein synthesis, while stop codons (UAA, UAG, UGA) signal the termination of protein synthesis.

Front

What is the amino acid sequence for the mRNA code AUGCCAGUAUGA?

Back

Met-Pro-Val.
