FLASHCARD QUESTION

Front

What is the Central Dogma of Molecular Biology?

Back

The Central Dogma describes the flow of genetic information from DNA to RNA to protein, outlining the processes of transcription and translation.

2.

FLASHCARD QUESTION

Front

What is transcription in the context of the Central Dogma?

Back

Transcription is the process of synthesizing RNA from a DNA template, where the DNA sequence is copied into a complementary RNA sequence.

3.

FLASHCARD QUESTION

Front

What is translation in the context of the Central Dogma?

Back

Translation is the process of synthesizing proteins from mRNA, where ribosomes read the mRNA sequence and assemble amino acids into a polypeptide chain.

4.

FLASHCARD QUESTION

Front

What is a codon?

Back

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

5.

FLASHCARD QUESTION

Front

What is the role of mRNA?

Back

mRNA (messenger RNA) carries the genetic information from DNA to the ribosome, where it serves as a template for protein synthesis.

6.

FLASHCARD QUESTION

Front

What is the role of tRNA?

Back

tRNA (transfer RNA) transports specific amino acids to the ribosome during translation, matching its anticodon with the corresponding codon on the mRNA.

7.

FLASHCARD QUESTION

Front

What is the significance of the start codon?

Back

The start codon (AUG) signals the beginning of translation and codes for the amino acid methionine, initiating protein synthesis.
