This type of membrane allows some substances to pass through but blocks others.
selectively permeable membrane
These biological catalysts speed up chemical reactions by lowering activation energy.
enzymes
DNA stands for Deoxyribonucleic Acid. DNA molecules consist of small units called
Nucleotides
This part of the cell cycle includes G1, S, and G2
interphase
This is the physical trait or appearance of an organism
phenotype
This type of transport moves molecules from high concentration to low concentration and does not require ATP.
passive transport
This is the specific region of an enzyme where the substrate binds.
What is the active site?
Adenine and guanine are double ringed structures called what?
Purines
During this phase of the cell cycle, DNA is copied
S phase
This is the genetic makeup or allele combination of an organism
genotype
Water moving across a membrane from low solute concentration to high solute concentration is called this.
osmosis
This process uses sunlight, carbon dioxide, and water to make glucose and oxygen.
Photosynthesis
Cytosine, Thymine & Uracil in RNA and single ringed structures called
pyrimidines
Mitosis produces genetically identical what?
daughter cells
A trait that is expressed when only one copy of the allele is present is called this
dominant
What will happen to red blood cell if it is placed inside a hypertonic solution?
It will shrink.
water is split using light energy to create oxygen, thus releasing hydrogen and electrons
photolysis
This process uses DNA as a template to make mRNA
transcription
Meiosis produces genetically different what?
haploid cells
In this inheritance pattern, both alleles are expressed at the same time, like red and white flowers producing red-and-white spotted flowers
codominance
This type of transport requires ATP because molecules move against the concentration gradient.
In the absence of oxygen this cannot enter the mitochondria
Pyruvic acid
This process uses mRNA codons to build a chain of amino acids.
translation
These two processes in meiosis help create genetic diversity.
crossing over and independent assortment
In this inheritance pattern, the heterozygous phenotype is a blend of both traits, like red and white flowers producing pink flowers
incomplete dominance
