Protein Synthesis Practice

Front

What is the function of ribosomes in cells?

Back

Ribosomes are the organelles where protein synthesis occurs, translating mRNA into amino acid sequences.

What is the complementary mRNA sequence to the DNA strand AACTGAA?

Front

What is protein synthesis?

Back

Protein synthesis is the process of assembling proteins based on the instructions encoded in DNA.

Front

What type of RNA is responsible for carrying genetic information from the nucleus to the ribosome?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What are the two main stages of protein synthesis?

Back

The two main stages are transcription (copying DNA to mRNA) and translation (reading mRNA to assemble proteins).

Front

What is the role of tRNA in protein synthesis?

Back

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

Front

Define transcription in the context of protein synthesis.

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is the role of the nucleus in protein synthesis?

Back

The nucleus houses the DNA, which contains the instructions for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

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