Front

What enables specialized cells such as skin cells and liver cells to perform specific activities?

Front

What is the central dogma of molecular biology?

Back

The process by which DNA is transcribed to RNA, which is then translated into protein.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the sites where amino acids are assembled into proteins.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains thymine, while RNA is single-stranded and contains uracil.

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 transfer RNA (tRNA)?

Back

tRNA transfers amino acids to the ribosome during protein synthesis.
