Unit 5: Central Dogma of Genetics

Front

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

Back

Uracil (U)

Front

Which of the following best describes a protein?

Back

A molecule composed of amino acids that performs various functions in the body.

Front

RNA contains the sugar

Back

ribose

Front

What is a codon?

Back

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

Front

What is the complementary base pair for adenine (A) in DNA?

Back

Thymine (T)

Front

What is the central dogma of molecular biology?

Back

The process by which the information in genes flows into proteins: DNA -> RNA -> 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 the function of ribosomes in the cell?

Back

Ribosomes are the sites of protein synthesis, where mRNA is translated into amino acid sequences.

Front

What are the building blocks of proteins?

Back

Amino acids.

Front

What is transcription in the context of genetics?

Back

The process of copying a segment of DNA into RNA.
