Unit 5: Central Dogma of Genetics

Front

Which nucleotide base is found in RNA but not in DNA?

Back

Uracil (U) is found in RNA but not in DNA.

Front

How does a mutation in a gene affect the phenotype of an organism?

Back

A mutation can change the protein produced, potentially altering the phenotype.

Front

Translate the following mRNA codon: GGA

Back

Glycine is the amino acid translated from the mRNA codon GGA.

Front

Translate the following mRNA codon: UCU

Back

Serine is the amino acid translated from the mRNA codon UCU.

Front

Translate the following mRNA codon: UAA

Back

UAA is a stop codon, signaling the end of protein synthesis.

Front

What is the Central Dogma of Molecular Biology?

Back

The Central Dogma describes the flow of genetic information from DNA to RNA to protein.

Front

What role does mRNA play in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that codes for a specific amino acid.

Front

What is the function of tRNA in translation?

Back

tRNA transports specific amino acids to the ribosome during protein synthesis.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can affect gene function.
