BIO 2 d protein synthesis
The property of a substance where its molecules are attracted to other molecules of the same kind and therefore stick together.
COHESION
What is the purpose of the flagellum?
MOVEMENT
TRUE OR FALSE
An important difference between viruses and living cells is that viruses cannot reproduce outside of cells.
TRUE
DNA stands for
deoxyribonucleic acid
The simple, three-nucleotide sequence on an mRNA molecule that codes for a specific amino acid.
codon
The property of a substance where its molecules are attracted to molecules of a different substance and therefore stick to a surface or other material.
ADHESION
What is the part of the cell responsible for the “rough” appearance of endoplasmic reticulum?
PROTEINS
What could be successfully treated with antibiotics?
BACTERIA
The four nitrogenous bases in DNA are Adenine, Guanine, Cytosine, and this one.
thymine
This enzyme is responsible for synthesizing a complementary strand of mRNA from a DNA template.
RNA polymerase
Complete the sentence:
Water is _________ that has a slightly ________ charge on the __________ side and a slightly _________ charge on the two ___________ sides.
Water is polar that has a slightly negative charge on the oxygen side and a slightly positive charge on the two hydrogen sides.
the brain/control center of the cell
NUCLEUS
Viruses replicate through?
Lysogenic and Lytic
The type of weak bond that holds the complementary nitrogenous base pairs (A-T and C-G) together.
Hydrogen bond
The process where the DNA code is copied into an mRNA molecule in the cell's nucleus.
transcription
Responsible for carrying coded information from the nucleus
mRNA
When an animal eats, food stays in the stomach for a period of time. When a unicellular organism, such as Paramecium, takes in food, the food is contained in which organelle?
VACUOLE
TRUE or FALSE
Bacteria reproduce asexually by binary fission.
TRUE
The final structure of DNA, described by Watson and Crick in 1953.
double helix
The process where the mRNA code is "read" by a ribosome to assemble a chain of amino acids (a protein).
translation
The parts of DNA that provide the code for proteins are the
NITROGENOUS BASES
PLANT
The protein structure that makes up the outside of viruses.
CAPSID
In 1950 Erwin Chargaff discovered that the percentage of adenine in DNA equals to percentage of thymine, and that the percentage of cytosine is equals the percentage of guanine.
This proved invaluable to the eventual discovery of which aspect of DNA?
structure
The type of RNA molecule that carries a specific amino acid to the ribosome and matches it to a codon.
tRNA or transfer RNA
