DNA and Protein Synthesis

Front

What is the structure of tRNA?

Back

tRNA (transfer RNA) is a molecule that helps decode a messenger RNA (mRNA) sequence into a protein. It carries amino acids to the ribosome during protein synthesis.

Front

What is mRNA?

Back

mRNA (messenger RNA) is a type of RNA that carries genetic information from DNA to the ribosome, where proteins are synthesized.

Front

Where does transcription occur in the cell?

Back

Transcription occurs in the nucleus of the cell.

Front

What is an anticodon?

Back

An anticodon is a sequence of three nucleotides in tRNA that pairs with a complementary codon in mRNA during protein synthesis.

Front

What are the RNA bases that pair with DNA base 'T'?

Back

The RNA base that pairs with DNA base 'T' is 'A' (adenine), which pairs with 'U' (uracil) in RNA.

Front

How many nucleotides are in one codon?

Back

One codon consists of three nucleotides.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into a polypeptide chain.

Front

What is the start codon for protein synthesis?

Back

The start codon is AUG, which codes for the amino acid methionine.

Front

What is the function of rRNA?

Back

rRNA (ribosomal RNA) is a component of ribosomes and plays a crucial role in protein synthesis by facilitating the binding of mRNA and tRNA.

Front

What is the process of translation?

Back

Translation is the process by which ribosomes synthesize proteins using the information encoded in mRNA.
