DNA, RNA & Protein Synthesis

Front

What is the role of transfer RNA (tRNA) in protein synthesis?

Back

Transfer RNA (tRNA) is responsible for bringing amino acids to the ribosome during translation, matching the amino acid to the corresponding codon on the mRNA.

Front

What is the start codon and its significance in translation?

Back

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

Front

What are the three main types of RNA involved in protein synthesis?

Back

The three main types of RNA are messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA).

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 is the difference between DNA and RNA?

Back

DNA contains deoxyribose sugar and thymine, while RNA contains ribose sugar and uracil instead of thymine.

Front

What is the function of ribosomal RNA (rRNA)?

Back

Ribosomal RNA (rRNA) forms the core of the ribosome's structure and catalyzes protein synthesis.

Front

What is the significance of the semi-conservative model of DNA replication?

Back

The semi-conservative model of DNA replication means that each new DNA molecule consists of one original strand and one newly synthesized strand, ensuring genetic continuity.

Front

What is a codon and its role in protein synthesis?

Back

A codon is a sequence of three nucleotides on mRNA that specifies a particular amino acid during protein synthesis.

Front

What is the process of translation?

Back

Translation is the process by which the sequence of nucleotides in mRNA is decoded to produce a specific polypeptide or protein.

Front

What happens during the elongation phase of translation?

Back

During elongation, amino acids are added one by one to the growing polypeptide chain as the ribosome moves along the mRNA.
