DefinitionWord
Copying DNA. Uses both strands of DNA as a template to form complementary strands.
Forms an interconnected network of tubules within cells. Rough ones synthesize proteins while smooth ones synthesize lipids and steroids
Part of the cell that makes proteins from amino acids. A main component in translation. Stuck on rough ER.
Occurs in many cooked starchy foods
A primary antibody is used against the antigen of interest; a subsequent, secondary ('indirect'), dye-coupled antibody is introduced that recognizes the primary antibody.
RNA molecule that provides the 'blueprint' for protein production.
Regulator of hemoglobin
The primary function of this is to process and package macromolecules, such as proteins and lipids, after their synthesis and before they make their way to their destination; it is
Display self and nonself antigens within a cell to the rest of the organism.
Property of magnetic nuclei that allows it to absorb an electromagnetic pulse and radiate it back out.
Cells that contain complex structures inside the membranes. The defining membrane-bound structure that sets them apart is the nucleus, or nuclear envelope, within which the genetic
Decodes mRNA into amino acids. Aids in translation.
Partitions replicated DNA in mitosis
Cells have two homologous copies of each chromosome (non-sex cells, 2n)
Bacteria that carry out photosythesis
Threadlike structures in bacteria that help them adhere to one another
The process of creating an equivalent RNA copy of a sequence of DNA
The iron-containing oxygen-transport protein in the red blood cells. Binds cooperativly and can bind 4 oxygen molecules.
NAD+, NADP+, FMN, FAD, Heme
An enzyme that creates a double-stranded DNA molecule from a single strand of RNA.
On the inner membrane of mitochondria and is used to carry electrons down the ELC
Tumor that grows without invading other tissues
Projections from neurons that recieve message from other neurons
Extended and specialized plasma membrane that wraps around nerve
Where does the oxygen plants produce come from?
Process of cellular that results in two exact copies of the cell.
Tumor that invades other tissues
What is another way to say lowest energy conformation or active conformation?
Sequences of DNA that can move around to different positions within the genome of a single cell, they can cause mutations and change the amount of DNA in the genome.
Moves the cell, important in muscle contraction and cell division
Signal to make cell kill itself
Used as a reducing agent. Can transfer its electron to another molecule.
Set of pathways that break down larger molecule into small units and release energy
An organism that produces complex organic compounds from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions
A unit of heredity in a living organism. It is normally a stretch of DNA that codes for a type of protein or for an RNA chain that has a function in the organism.
DefinitionWord
DNA sequence that is NOT removed from DNA durring splicing
Two different genes (eg. Hh or Bb)
genes that determine which parts of the body form what body parts
Two of the same genes (eg. HH or hh)
Biological process that causes an organism to develop its shape.
A cell or an organism having half of the number of chromosomes of normal cells. (eg. sex cells, n)
Transfers genetic information to another cell is typically to isolate, multiply, or express the insert in the target cell.
_________ gel electrophoresis is a method used in biochemistry and molecular biology to separate DNA, RNA or protein. Nucleic acid molecules are separated by size.
Trap in sunlight.
Prevents the transcription of DNA. Coded by regulator genes.
Is the largest or the smallest at the bottom of the SDS page gel?
Locomotory structures in bacteria
What is Tim?
Quinones and Coenzyme Q are exaples of what?
Middle layer of tissue
Involves chromogenic reporters and substrates which produce some kind of observable color change to indicate the presence of antigen or protein.
Improves the function of a protein
Energy remains constant, even though it forms a change.
'Reads' an intact DNA strand as a template and uses it to synthesize the new strand.
Interferes with the expression of a particular gene. Also serves as an antiviral mechanism and shapes chromatin.
What amino acid is the start codon?
Any substance (as a toxin or enzyme) that stimulates an immune response in the body (especially the production of antibodies)
In this the electron transport chain accepts the electron from photosynthesis.
Used in anabolic reactions like lipid and nucleic acid synthesis. In plants, it is reduced during the light reaction of photosynthesis.
Chemicals that cause changes in the DNA sequence and cause cancer.
Proteins use hydrolysis of _____ as a 'timer' for the 'on' response.
Simultaneous polymerization and depolymerization of different MT's in the same pool at steady state.
Outter layer of tissue
Reduced form of NADP
What makes a compund more reduced?
Is an organism that uses organic carbon for growth.
Moves materials with in the cell and form mitotic spindles.
Premature death of cells and tissues. Can be caused by infection, toxins, trauma, etc.
Specialization of cells for different structures and functions
How fat is Tim?
DefinitionWord
Used by the immune system to identify and neutralize foreign objects
The liquid found inside a cell
Converts chemical energy into ATP. Cellular respiration. Have their own DNA
DNA sequence that is removed from DNA during splicing. Codes for nothing. NOTHING.
Sequences that are evolutionarily related are __________.
Cells of early embryo can become any cell type or tissue
Is one of the germ layers formed during embryogenesis. It forms the epithelial lining of multiple systems.
a small molecule that binds specifically to a larger one
Total entropy (disorder) in the universe is continually increasing
Process of cellular replication that results in the formation of gametes.
Pulse-like voltage wave that travels on 'excitable' membranes
Transfers a specific active amino acid to a growing polypeptide chain at the ribosomal site of protein synthesis during translation.
Cleaves DNA at restriction sites. Leaves sticky ends.
What is the primary source of free energy driving protein folding?
Conduct photosynthesis. Contains chlorophyll. Have their own DNA.
Molecules that differ only in configuration of the atoms around one or more carbons
What kind of magic does Tim use?
A phase early in the development of most animal embryos, during which the morphology of the embryo is reorganized to form the three germ layers: ectoderm, mesoderm, and endoderm
Increase in the concentration of chemical nutrients in an ecosystem to an extent that increases the primary productivity of the ecosystem. Such as algae on a lake.
the spread of cancer from one organ to another. Very inefficient.
Put two strands of DNA together
What states 'There is no way for a protein to sample all conformations while folding because there are too many'?
Partitioning of cytoplasm
Organisms that lack a cell nucleus. DNA is stored in the nucleoid. High surface area to volume ratio.
lipid-soluble molecule usually synthesized by microorganisms to transport ions across the lipid bilayer of the cell membrane.
