U6: Translation

Front

What is the role of mRNA in protein synthesis?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where proteins are synthesized.

Front

What are codons?

Back

Codons are sequences of three nucleotides on mRNA that correspond to specific amino acids.

Front

What is the function of tRNA?

Back

tRNA (transfer RNA) transports amino acids to the ribosome during protein synthesis.

Front

What is the site of protein synthesis in a cell?

Back

Ribosomes are the cellular structures where protein synthesis occurs.

Front

What is the first step in protein synthesis?

Back

The first step is transcription, where DNA is used as a template to create mRNA.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where the sequence of codons in mRNA is used to assemble amino acids into a polypeptide chain.

Front

What is the complementary DNA triplet for TTT?

Back

The complementary DNA triplet for TTT is AAA.

Front

What amino acids are coded by the mRNA codon UUU?

Back

The mRNA codon UUU codes for the amino acid phenylalanine.

Front

What is the correct sequence of events in protein synthesis?

Back

1. DNA serves as a template for mRNA (Transcription). 2. mRNA moves to ribosomes. 3. tRNA brings amino acids to the ribosome. 4. Polypeptides are formed.

Front

What is the role of ribosomes in cells?

Back

Ribosomes are responsible for synthesizing proteins by translating mRNA into amino acid sequences.
