3.1 Protein Synt Practice Test Flashcardizz

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies a particular amino acid or a stop signal during protein synthesis.

Front

What amino acid is represented by the codon UUA?

Back

Leucine

Front

What is the amino acid for the codon CAA?

Back

Glutamine (Gln)

Front

What is the transcribed mRNA sequence for the DNA sequence ATCCGTC?

Back

UAGGCAG

Front

Which organelle is responsible for protein synthesis?

Back

Ribosome

Front

What is the start codon and its significance?

Back

The start codon is AUG, which codes for Methionine and signals the start of protein synthesis.

Front

What is the role of tRNA in protein synthesis?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during protein synthesis, matching its anticodon with the mRNA codon.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.

Front

What is a stop codon?

Back

A stop codon is a nucleotide triplet within mRNA that signals the termination of translation, indicating that the protein synthesis is complete.

Front

What is the function of ribosomes in cells?

Back

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