Transcription and Translation and DNA Fingerprinting

Front

What is transcription?

Back

Transcription is the process by which the DNA sequence of a gene is copied into mRNA. It occurs in the nucleus of the cell.

Front

What is translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is used to synthesize proteins. It occurs in the ribosomes.

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosomes, where proteins are synthesized.

Front

What is the role of tRNA?

Back

tRNA (transfer RNA) brings amino acids to the ribosome during protein synthesis, matching them to the codons in mRNA.

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 protein synthesis.

Front

What is DNA fingerprinting?

Back

DNA fingerprinting is a technique used to identify individuals based on unique patterns in their DNA.

Front

What is the significance of amino acid interactions in proteins?

Back

The chemical interactions of amino acids determine the way a protein folds, which is crucial for its function.

Front

What organelle is responsible for producing energy for protein synthesis?

Back

Mitochondria are the organelles that produce ATP, the energy currency needed for protein synthesis.

Front

What is the difference between DNA and RNA?

Back

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

Front

What is the function of ribosomes?

Back

Ribosomes are the cellular structures where protein synthesis occurs, translating mRNA into polypeptide chains.
