Unit 5 & 6 - Protein Synthesis

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the genetic instructions for the development and function of living things, including the sequence of amino acids in proteins.

Front

What are the four nucleotides found in DNA?

Back

Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).

Front

What is a frameshift mutation?

Back

A frameshift mutation occurs when nucleotides are added or deleted from the DNA sequence, altering the reading frame and potentially changing all subsequent amino acids.

Front

What determines the sequence of amino acids in a protein?

Back

The sequence of nucleotides in the DNA determines the sequence of amino acids in a protein.

Front

What is the significance of the genetic code?

Back

The genetic code is universal, meaning that the same nucleotides code for the same amino acids across different organisms.

Front

What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into RNA, specifically messenger RNA (mRNA), which carries the genetic information to the ribosome.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes read the mRNA sequence and assemble amino acids into a polypeptide chain, forming a protein.

Front

What is the difference between point mutation and frameshift mutation?

Back

A point mutation involves a change in a single nucleotide, while a frameshift mutation involves the addition or deletion of nucleotides, affecting the entire reading frame.

Front

How do environmental factors influence protein synthesis?

Back

Environmental factors such as temperature and pH can affect the structure and function of proteins, potentially impacting their synthesis.

Front

What is the function of ribosomes in protein synthesis?

Back

Ribosomes are the cellular machinery that facilitate the translation of mRNA into a protein by linking amino acids together.
