Transcription and Translation

Front

What is the role of rRNA in protein synthesis?

Back

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

Front

What is transcription?

Back

Transcription is the process of making an mRNA copy from a DNA template.

Front

What is translation?

Back

Translation is the process of decoding mRNA to synthesize proteins.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that specifies an amino acid.

Front

How many nucleotides are in a codon?

Back

A codon is made up of 3 nucleotides.

Front

What is the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in mRNA is translated into amino acids.

Front

Can a single codon specify more than one amino acid?

Back

No, a single codon specifies only one amino acid.

Front

What is the significance of start and stop codons?

Back

Start codons signal the beginning of protein synthesis, while stop codons signal the end.

Front

What is the function of tRNA in translation?

Back

tRNA (transfer RNA) carries amino acids to the ribosome and matches them to the codons in mRNA.

Front

What is the difference between DNA and RNA?

Back

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