What organelle allows a cell to produce proteins?
ribosome
200
What nitrogen bases does DNA contain?
adenine, guanine, cytosine, thymine
200
Where does translation occur?
At a ribosome, (either free floating ribosome in the cytoplasm or attached ribosome on the ER)
200
What organelles do bacteria contain?
No true organelles, some have ribosomes. (they do have a cell membrane as well)
200
Name the only two parts of a virus's structure:
DNA, protein coat
200
Name TWO days RNA is different than DNA
RNA has Uracil (DNA has Thymine) RNA is single stranded (DNA is double stranded) RNA can leave the nucleus,(DNA cannot)
300
what are the sides of DNA made of?
sugar and phosphate groups
300
What is the product of transcription?
A molecule of mRNA
300
What are archaea bacteria?
bacteria that live in extreme environments such as a hot spring or volcano
300
What must a virus have to reproduce?
It must have a host cell to reproduce within. It cannot reproduce independently.

Bacterial reproduction is called
binary fission

How does DNA affect the phenotypes of a person?
Differences in DNA sequences will results in different proteins, which results in different physical traits.
500
How does the ribosome read the mRNA molecule?
it is read in 3 letter sequences called "CODONS"

What do some bacteria produce that will protect them while they enter a dormant state
endospore

True or false : All bacteria and viruses make you sick
False: Not all bacteria are pathogenic. Some viruses cannot infect humans.
