Transcription and Translation

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the organelles that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

How many bases are in a codon?

Back

A codon consists of 3 bases.

Front

What base pairs with adenine (A) during RNA transcription?

Back

During RNA transcription, adenine (A) pairs with uracil (U).

Front

Is RNA single-stranded or double-stranded?

Back

RNA is single-stranded.

Front

What is the sequence of events in protein synthesis?

Back

The correct order is transcription followed by translation.

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into messenger RNA (mRNA).

Front

What is translation in the context of protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins by reading the sequence of mRNA.

Front

What role does mRNA play in protein synthesis?

Back

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

Front

What are the three main types of RNA involved in protein synthesis?

Back

The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

Front

What is the role of tRNA in translation?

Back

tRNA transports specific amino acids to the ribosome and matches them to the corresponding codon on the mRNA.
