Protein Synthesis Review 2023

Front

What is translation in protein synthesis?

Back

Translation is the process that joins amino acids at the ribosome using mRNA codons as the source of code.

Front

Which base does not exist in RNA?

Back

Thymine (T) does not exist in RNA; instead, RNA contains Uracil (U).

Front

What is the amino acid sequence for the mRNA sequence AUGCAGCAAUGG?

Back

The amino acid sequence is met-gln-gln-trp.

Front

What type of RNA carries the code from DNA for producing proteins?

Back

mRNA (messenger RNA) carries the code from DNA for producing proteins.

Front

What are amino acids used to make?

Back

Amino acids are used to make proteins.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template that carries genetic information from DNA to the ribosome for protein synthesis.

Front

What is the function of tRNA in translation?

Back

tRNA (transfer RNA) brings the appropriate amino acids to the ribosome during translation.

Front

What is the start codon in mRNA?

Back

The start codon in mRNA is AUG, which codes for the amino acid Methionine.

Front

What are codons?

Back

Codons are sequences of three nucleotides in mRNA that specify a particular amino acid.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains Thymine (T), while RNA is single-stranded and contains Uracil (U) instead of Thymine.
