What are the TWO components of the DNA backbone?
nucleotide and phosphate group
deoxyribose sugar and nitrogen base
nitrogen base and nucleotide

What is the process that duplicates DNA called?
DNA Replication
Transcription
Translation
None of the above
What is the purpose of the mitochondria?
The mitochondria provide the energy needed to power chemical reactions
The mitochondria is the organelle that processes and packages proteins
Mitochondria receives proteins from the rough ER and directs that protein to the proper location
None of the above
Which best defines a gene?
A gene is a unit of protein that contains the genetic code.
A gene is a unit of DNA that contains code for the creation of one protein.
A gene is a unit of DNA that contains the code for the creation of amino acids.
None of the above

Which organelle houses the DNA, the genetic material of the cell?
the endoplasmic reticulum
the mitochondria
the lysosome
the nucleus
Protein synthesis requires
replication then transcription
transcription then translation
replication then translation
translation then transcription
Which organelle makes proteins?
the ribosome
the mitochondria

the nucleus
Translation can be described as
the process of making a protein in the nucleus
the transfer of the instructions from the nucleus to the cytoplasm
the process in which the genetic code in mRNA is read to make a protein
the transfer of genetic instructions in DNA to mRNA
