Transcription and Translation

Front

What is the process of transcription?

Back

Transcription is the process by which the genetic information in DNA is copied into messenger RNA (mRNA).

Front

What are the base pairing rules for RNA during transcription?

Back

In RNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).

Front

What is the role of mRNA in protein synthesis?

Back

mRNA serves as a template for translating the genetic code into a sequence of amino acids during protein synthesis.

Front

What is a codon?

Back

A codon is a sequence of three nucleotides in mRNA that corresponds to a specific amino acid or stop signal during translation.

Front

What is the start codon and its significance?

Back

The start codon is AUG, which signals the beginning of translation and codes for the amino acid methionine.

Front

What is the difference between DNA and RNA?

Back

DNA contains the bases adenine (A), thymine (T), cytosine (C), and guanine (G), while RNA contains adenine (A), uracil (U), cytosine (C), and guanine (G).

Front

What is the function of ribosomes in translation?

Back

Ribosomes are the cellular machinery that facilitate the translation of mRNA into a polypeptide chain by reading codons and assembling amino acids.

Front

What is the role of tRNA in protein synthesis?

Back

Transfer RNA (tRNA) carries specific amino acids to the ribosome and matches them to the corresponding codon on the mRNA.

Front

What is a polypeptide chain?

Back

A polypeptide chain is a sequence of amino acids linked together by peptide bonds, forming a protein.

Front

What is the significance of the genetic code?

Back

The genetic code is a set of rules that defines how the sequence of nucleotides in DNA and RNA is translated into the amino acid sequence of proteins.
