Unit 5: Central Dogma of Genetics

Front

What type of mutation causes a premature stop codon to appear in the amino acid sequence?

Back

Nonsense Mutation

Front

What type of mutation involves substituting a DNA base with a different base but still forms the same protein?

Back

Silent Mutation

Front

A frameshift mutation where a nucleotide base is added to the DNA sequence is called?

Back

Insertion Mutation

Front

DNA has a _____________ structure.

Back

double helix

Front

Translate the following mRNA codon: AUG

Back

Methionine

Front

What is the primary function of mRNA in the central dogma of genetics?

Back

To carry genetic information from DNA to the ribosome for protein synthesis.

Front

What is a missense mutation?

Back

A mutation that results in a different amino acid being incorporated into a protein.

Front

What is a deletion mutation?

Back

A mutation where one or more nucleotide bases are removed from the DNA sequence.

Front

What is the role of tRNA in protein synthesis?

Back

To transport amino acids to the ribosome and match them to the mRNA codons.

Front

What is the significance of the start codon AUG?

Back

It signals the beginning of translation and codes for the amino acid Methionine.
