Central Dogma: Protein Synthesis

Transcription & Translation

Multiple Choice

What does the word "synthesis" mean?

• to dehydrate

• to make

• to destroy

• to combine

​What causes transcription?

​Signals from the environment, environmental factors, activate proteins called transcription factors. These proteins bind to sections of a gene and control transcription, this process can determine when and how much protein product is made by a gene.

Multiple Choice

What can cause a gene to be activated to start transcription?

• environmental factors

• DNA helicase

• mRNA

• RNA polymerase

Multiple Choice

Can DNA leave the nucleus?

• yes

• no

Multiple Choice

Which of the following about DNA and RNA are true?

• mRNA has the nitrogenous base Uracil

• mRNA has the nitrogenous base Thymine

• mRNA is a double helix

• DNA can leave the nucleus

Multiple Choice

Where does transcription take place?

• Nucleus

• Cytoplasm

• Cell membrane

• Ribosome

Multiple Choice

What protein enzyme is responsible for transcribing the DNA into mRNA ?

• Nucleotides

• Monosaccharides

• RNA polymerase

• ATP

Multiple Choice

How can DNA information leave the nucleus to go to the ribosome?

• DNA can leave the nucleus at any time

• DNA has to be transcribed into mRNA

• DNA splits into three parts and leaves

• Ribosomes enter the nucleus and copy the instructions

Multiple Choice

Where does translation take place?

• Nucleus

• cell wall

• Cell membrane

• Ribosome

Multiple Choice

What is the second step of Protein synthesis?

• transcription

• translation

Multiple Choice

Where does mRNA go once it leaves the nucleus?

• to the cell membrane

• to the ribosome

• to the nucleoid

• to the lysosomes

-Anticodons stick to the mRNA codons
