Protein Synthesis Flashcard (STAAR and Short)

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

How many nucleotides make up a codon?

Back

3

Front

What is the purpose of protein synthesis?

Back

The purpose of protein synthesis is to translate the genetic code into a specific sequence of amino acids, forming proteins.

Front

What is mRNA and its role in protein synthesis?

Back

mRNA (messenger RNA) is a type of RNA that carries the genetic information from DNA to the ribosome, where it is translated into a protein.

Front

What is the difference between DNA and RNA in terms of nitrogenous bases?

Back

In DNA, the nitrogenous base Thymine (T) is present, while in RNA, Uracil (U) replaces Thymine.

Front

What is transcription in the context of protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA, where the DNA sequence is transcribed into a complementary RNA sequence.

Front

What is translation in the context of protein synthesis?

Back

Translation is the process by which the sequence of nucleotides in mRNA is decoded to produce a specific sequence of amino acids, forming a protein.

Front

What is the role of ribosomes in protein synthesis?

Back

Ribosomes are the cellular structures where translation occurs, facilitating the assembly of amino acids into proteins based on the mRNA sequence.
