Chemistry
In an atom, these two particles are equal in number.
Protons and electrons
Eukaryotic cells differ from prokaryotic cells because they contain these structures.
Nucleus and membrane-bound organelles
mRNA is formed from DNA during this process.
Transcription
Four
Half
These are the alternative forms of a gene for a specific trait, such as brown eyes or blue eyes.
Alleles
Which of the 4 biomolecules is good for short term energy? Which is good for long term energy storage?
Carbohydrates
Lipids
This cellular structure builds proteins and can be found in these 2 locations.
Ribosome
In cytoplasm or on the rough ER
DNA polymerase is used in this process and works in this direction.
DNA replication
5' to 3' direction
The cell grows and replicates its DNA during this cell cycle phase.
Interphase
This type of cross results in offspring with an intermediate phenotype. (Ex: red and white parent generation results in pink offspring)
Incomplete dominance or Blending
In this type of molecule, the electrons are shared unequally between the 2 atoms.
Polar
This process allows the movement of water across a membrane from high to low concentration.
Osmosis
The production of proteins from mRNA is called
Translation
Crossing over occurs during this process and this phase.
Meiosis
Prophase I
Men with an X-linked disorder can pass the gene for the disorder to their
Daughters only
An atom with 12 electrons would have this many electrons in its valence shell.
2 electrons
This process requires energy to move particles across the cell membrane. Name one specific example.
Active transport
Ex: Pinocytosis, phagocytosis, receptor-mediated endocytosis
RNA nucleotides are made of these 3 parts.
ribose sugar
phosphate group
nitrogenous base
Mitosis starts with (haploid/diploid) cells. Meiosis starts with (haploid/diploid) cells.
diploid
diploid
A child has albinism (a recessive trait) but his parents do not. What must the genotypes of the parents be?
Heterozygous
In ionic bonds, the electrons are _________. But in covalent bonds, the electrons are _________.
lost by one atom, gained by another (donated/accepted, given up/received)
shared
All cells have these 2 structures in common.
This type of mutation is caused by the change of one DNA nucleotide.
Point mutation
This process prevents the cell from passing along damaged DNA and keeps an organism's cell number at an appropriate level.
Apoptosis
A man with AB blood and a woman with B blood have a child. What are the chances this child will have O blood?
0% - No chance
