DNA Replication & Protein Synthesis

Front

What is DNA replication?

Back

The process by which a cell makes an exact copy of its DNA before cell division.

Front

What is the role of mRNA in protein synthesis?

Back

mRNA carries the genetic information from the nucleus to the ribosome for protein synthesis.

Front

Where is DNA located in a eukaryotic cell?

Back

DNA is located in the nucleus.

Front

What is a codon?

Back

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

Front

What is the start codon and its significance?

Back

The start codon is AUG, which signals the beginning of protein synthesis and codes for the amino acid Methionine.

Front

What is the function of tRNA?

Back

tRNA transports specific amino acids to the ribosome during protein synthesis.

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 is transcription?

Back

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

Front

What is translation?

Back

Translation is the process of decoding mRNA to synthesize a protein at the ribosome.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, linking amino acids together to form proteins.
