What are exons?

Back

Exons are the parts of messenger RNA that are spliced together and used for protein synthesis.

Front

What are introns?

Back

Introns are the parts of messenger RNA that are not used for protein synthesis and are removed during RNA processing.

Front

What is the relationship between RNA and DNA during transcription?

Back

The RNA formed during transcription is complementary to one strand of DNA.

Front

What type of RNA carries instructions for assembling a protein?

Back

Messenger RNA (mRNA) carries the instructions for assembling a protein.

Front

How many different possible 3-base codons are there?

Back

There are 64 different possible 3-base codons.

Front

What is transcription?

Back

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

Front

What is translation?

Back

Translation is the process of synthesizing proteins from messenger RNA.

Front

What role does ribosomal RNA (rRNA) play in protein synthesis?

Back

Ribosomal RNA (rRNA) forms the core of the ribosome's structure and catalyzes protein synthesis.

Front

What is the function of transfer RNA (tRNA)?

Back

Transfer RNA (tRNA) carries amino acids to the ribosome during protein synthesis.

Front

Define codon.

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid.
