Dna Transcription and Translation

Front

What is DNA transcription?

Back

The process of copying a segment of DNA into RNA, specifically messenger RNA (mRNA), which carries the genetic information needed for protein synthesis.

Front

What is the role of mRNA in protein synthesis?

Back

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

Front

What is the start codon in mRNA?

Back

AUG, which codes for the amino acid Methionine and signals the start of translation.

Front

What is translation in the context of protein synthesis?

Back

The process by which ribosomes read the sequence of mRNA and assemble amino acids into a polypeptide chain, forming a protein.

Front

What is tRNA and its function?

Back

Transfer RNA (tRNA) is responsible for bringing the correct amino acids to the ribosome during translation, matching them to the mRNA codons.

Front

What is a codon?

Back

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

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.

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.

Front

What are the four bases of RNA?

Back

Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).

Front

What is the process of RNA splicing?

Back

RNA splicing is the modification of the pre-mRNA transcript where introns are removed and exons are joined together to form mature mRNA.
