What does DNA stand for?

DNA stands for deoxyribonucleic acid.

What is the function of mRNA in protein synthesis?

mRNA (messenger RNA) serves as a template during protein synthesis by carrying the genetic information from the DNA in the cell's nucleus to the ribosomes in the cytoplasm. The ribosomes read the sequence of nucleotides in the mRNA and use this information to assemble the correct sequence of amino acids to form a protein. Essentially, mRNA acts as a messenger that conveys the instructions for building proteins from the DNA to the protein-making machinery of the cell.

Where does protein synthesis occur in a eukaryotic cell?

Protein synthesis in a eukaryotic cell occurs primarily in the cytoplasm, specifically on ribosomes. The process involves transcription of DNA into mRNA in the nucleus, which is then transported to the cytoplasm where ribosomes read the mRNA and synthesize proteins by linking amino acids together in the order specified by the mRNA sequence.

What is the role of tRNA in protein synthesis?

tRNA, or transfer RNA, plays a crucial role in protein synthesis by transferring specific amino acids to the ribosome during translation. Each tRNA molecule carries a specific amino acid and has an anticodon region that pairs with the complementary codon on the mRNA. By recognizing the codon and delivering the correct amino acid, tRNA helps in assembling the amino acids in the correct order to form a protein according to the genetic information encoded in the mRNA.

What is the significance of the start codon in protein synthesis?

The start codon, typically AUG, marks the initiation of protein synthesis and helps in identifying the correct reading frame during translation. It signals the ribosome to begin translating the mRNA molecule into a specific amino acid sequence, starting with methionine. Therefore, the start codon plays a crucial role in ensuring that the correct amino acids are brought together in the right sequence to form a functional protein.

How is the genetic code translated into a specific amino acid sequence?

The genetic code is translated into a specific amino acid sequence through a process called translation. During translation, messenger RNA (mRNA) is read by ribosomes, which are cellular machinery that use transfer RNA (tRNA) molecules to bring specific amino acids to the ribosome according to the codons on the mRNA. Each codon on the mRNA corresponds to a specific amino acid, and as the ribosome moves along the mRNA, it joins the amino acids together to form a polypeptide chain, which ultimately folds into a functional protein. This process repeats for each codon, translating the genetic information from DNA into proteins.

What is the purpose of the ribosomes in protein synthesis?

Ribosomes play a crucial role in protein synthesis by serving as the site where messenger RNA (mRNA) is translated into a polypeptide chain. They help facilitate the assembly of amino acids into proteins by decoding the genetic information carried by mRNA. Ribosomes are responsible for catalyzing the formation of peptide bonds between amino acids, ultimately leading to the production of functional proteins that are essential for various cellular processes.

What is the difference between transcription and translation in protein synthesis?

Transcription is the process in which the information in DNA is copied into messenger RNA (mRNA) by RNA polymerase. This occurs in the nucleus of eukaryotic cells and serves as a template for protein synthesis. On the other hand, translation is the process in which the mRNA is decoded by ribosomes to synthesize a specific protein. During translation, transfer RNA (tRNA) molecules bring specific amino acids to the ribosome based on the mRNA codons, forming a polypeptide chain that will eventually fold into a functional protein.

What are the three steps involved in transcription?

Transcription involves three main steps: initiation, where the RNA polymerase binds to the DNA at the promoter region; elongation, where the polymerase reads the DNA template strand and synthesizes the RNA transcript; and termination, where the polymerase reaches a termination sequence and releases the RNA transcript.

What are the three steps involved in translation?

The three main steps involved in translation are initiation, elongation, and termination. During initiation, the ribosome assembles around the mRNA and the first tRNA molecule enters the ribosome. In elongation, the ribosome moves along the mRNA, matching tRNA molecules to the corresponding codons and forming a polypeptide chain. Finally, termination occurs when a stop codon is reached, signaling the end of translation and the release of the completed protein.
