Protein Synthesis, Mutations, and Epigenetic review

Front

What are the three base segments of mRNA called?

Back

Codons are the three base segments of mRNA that code for specific amino acids.

Front

What amino acid does the mRNA codon 'CCU' code for?

Back

The mRNA codon 'CCU' codes for the amino acid Proline.

Front

True or False: Epigenetic changes can be passed on to future generations.

Back

True. Epigenetic changes can be inherited by future generations.

Front

What is the study of changes in organisms caused by modification of gene expression rather than alteration of the genetic code itself?

Back

Epigenetics is the study of changes in gene expression without altering the genetic code.

Front

Which factors can affect the epigenome?

Back

Nutrition, exercise, and stress can all affect the epigenome.

Front

Define protein synthesis.

Back

Protein synthesis is the process by which cells generate new proteins, involving transcription and translation.

Front

What is transcription in protein synthesis?

Back

Transcription is the process of copying a segment of DNA into mRNA.

Front

What is translation in protein synthesis?

Back

Translation is the process where ribosomes synthesize proteins using mRNA as a template.

Front

What role do ribosomes play in protein synthesis?

Back

Ribosomes are the cellular machinery that facilitate the translation of mRNA into proteins.

Front

What is a mutation?

Back

A mutation is a change in the DNA sequence that can lead to changes in protein structure and function.
