HESI REVIEW- BIOLOGY

Across
Type of cell that lacks a defined nucleus and does not contain membrane- bound organelles
Nitrogenous base that bonds with adenine
Any of many cell "organs" or organized components
Three-base sequence of mRNA
Contain all of the genetic information for the regeneration of the cell and instructions for the function of the cell
6CO2+6H20+Light Energy-->C6H12O6+6O2
Alternate versions of a gene
Process in which cells engulf food particles through the cell membrane
Packages, processes, and ships organelles; transports proteins from the ER throughout the cell
Produces cell energy; found in most eukaryotic cells and are the site of cellular respiration
Cycle that occurs in the mitochondrion during cellular respiration
Nucleic acid found in both the nucleus and cytoplasm of the cell; occurs in 3 forms
Process that determines how reproductive cells divide in a sexually reproducing organism
Endoplasmic reticulum that lacks ribosomes and responsible for the detoxification and metabolism of multiple molecules
Reproduction that involves two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
Long chains, or polymers, of sugars that functions as storage, structure, and energy; the backbone of important molecules such as DNA and RNA
Type of fatty acid with no double bonds
Trait in an organism that contains different alleles
Down
Intracellular digestion, acidic environment, and hydrolyzes proteins, fats, sugars, and nucleic acids
The process of cell division occurs in five stages before pinching into two in a process called _______

Stage of mitosis where chromosomes gather on either side of the new separating cell
Functions as a messenger from the original DNA helix in the nucleus to the ribosomes in the cytosol or on the rough ER
Phosphate-containing fat molecules; form the bilayer of a cell membrane
Sum of all chemical reactions that occur in an organism
RNA involved in protein synthesis; transfers a specific amino acid to the ribosome and binds it to the mRNA
Nitrogenous base that bonds with guanine
_____ transport chain is the part of cellular respiration that produces the greatest amount of ATP
Process during protein synthesis in which the DNA molecule is used as a template to form mRNA
Within the biologic hierarchic system of organization, this branch is the least inclusive
Type of cell with a membrane enclosed nucleus and a series of membrane organelles that carry out the functions of the cell
Organelles that read the RNA produced in the nucleus and translate the genetic instructions to produce proteins
Stage in mitosis where all chromosomes align along the metaphase plate (center of the cell)
Endoplasmic reticulum covered with ribosomes responsible for protein synthesis and membrane production
Stage of mitosis where the chromosomes are visibly separate with two noticeable sister chromatids
