Diffusion is______________
The passive movement of molecules along a concentration gradient
The active movement of molecules along a concentration gradient
Dis-arming of nuclear weapons
A concentration gradient ________________
moves from regions of high concentration to low concentration
moves from regions of low concentration to high concentration
is like a grading curve
a scale of concentrations
hypertonic
is Steve Martin
is the higher concentration solution
is the lower concentration solution
is neither higher nor lower concentration
is a kid on pixie stix
hypotonic
a hippo's tonic and gin
hyper- = ?
having a lot of something
having nothing
hypo- = ?
Not a lot of something
A big deal
Osmosis is
the active movement of water molecules through a membrane
the passive movement of water through a permeable membrane
the passive movement of water through a semi-permeable membrane
diffusion of water from one place to another
Osmosis is the movement of water from the
hypotonic to the hypertonic
hypertonic to the hypotonic
good to the bad
big to the small
hard to the soft
Which has a nucleus?
eukaryote
prokaryote
the rock lobster
Which is not usually as complex or as large as the other?
An Organelle is ___________
a membrane bound substructure in the cell.
an organ
rare in cells
only found in prokaryotes
hard to define
Which of these is not an organelle?
ribosome
vacuole
vesicle
plastid
Which of these organelles have their own DNA?
Endoplasmic Reticulum
golgi body
mitochondria
the Chloroplast is the most famous plastid type.
Plastids are found in both plant and animal cells.
Mitochondria:
posses their own DNA inherited from the maternal line
are energy factories for the cell, and produce ATP
have an inner and an outer membrane
are unique only to animal cells
Plastids have their own DNA.
In terms of DNA and/or RNA, replication is:
when the cell copies itself
the creation of mRNA
The synthesis of a duplicate copy of DNA from a template pair of strands
During replication, the double stranded DNA is separated by ____
DNA helicase
RNA helicase
zipper gene
zipper enzyme
The step from DNA to RNA is called
Transcription
Translation
Replication
What does DNA stand for?
Deoxyribonucleic acid
Deoxixribonucleic acid
Deoxinucleic acid
What is tRNA?
small RNA molecules containing 75 to 95 nucleotides and carriers of amino acids and participate in protein synthesis.
the transcriptional blue print for a protein that is used to code the proteins structure
used to make copies of DNA during replication
Which of these occur inside the nucleus?
replication
transcription
translation
________: long chains of DNA wrapped around each other. DNA exists like this only during limited periods of the cells life, and DNA is not really usable in this bundled structure.
Chromosome
Chromatin
Chromatid
_______: how DNA usually exists within the cell, in a loose, usable state within the nucleus. DNA + Structural Proteins (such as histones).
Chromasome
Comes from a word that means "color"
"chromo"
"some"
Comes from a word that means "body"
"Chromo"
"Some"
A structural protein that DNA is wrapped around in the nucleus:
histone
