Back

ACCGUU

Front

What is the flow of genetic information?

Back

DNA-RNA-protein

Front

Frameshift Mutation

Front

How did a puppy in a family of pitbulls with grey fur end up with black fur?

Back

A genetic mutation changed the puppy's fur color.

Front

What is a nucleotide?

Back

The basic building block of DNA and RNA, consisting of a sugar, phosphate group, and a nitrogenous base.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is a substitution mutation?

Back

A mutation where one nucleotide is replaced by another, potentially altering the protein produced.

Front

What is a silent mutation?

Back

A mutation that does not change the amino acid sequence of a protein.

Front

What is the function of tRNA?

Back

tRNA transports amino acids to the ribosome during protein synthesis.
