Nitrogenous base that bonds with adenine
7
Any of many cell "organs" or organized components
8
Three-base sequence of mRNA
9
Contain all of the genetic information for the regeneration of the cell and instructions for the function of the cell
13
6CO2+6H20+Light Energy-->C6H12O6+6O2
17
Alternate versions of a gene
18
Process in which cells engulf food particles through the cell membrane
19
Packages, processes, and ships organelles; transports proteins from the ER throughout the cell
23
Produces cell energy; found in most eukaryotic cells and are the site of cellular respiration
24
Cycle that occurs in the mitochondrion during cellular respiration
25
Nucleic acid found in both the nucleus and cytoplasm of the cell; occurs in 3 forms
26
Process that determines how reproductive cells divide in a sexually reproducing organism
30
Endoplasmic reticulum that lacks ribosomes and responsible for the detoxification and metabolism of multiple molecules
31
Reproduction that involves two cells that contribute genetic material to daughter cells, resulting in significantly greater variation
32
Long chains, or polymers, of sugars that functions as storage, structure, and energy; the backbone of important molecules such as DNA and RNA
33
Type of fatty acid with no double bonds
34
Trait in an organism that contains different alleles
Down
1
Intracellular digestion, acidic environment, and hydrolyzes proteins, fats, sugars, and nucleic acids
3
The process of cell division occurs in five stages before pinching into two in a process called _______
4
Unique molecule specific to a particular organism and contains the code necessary for replication
5
Stage of mitosis where chromosomes gather on either side of the new separating cell
10
Functions as a messenger from the original DNA helix in the nucleus to the ribosomes in the cytosol or on the rough ER
11
Phosphate-containing fat molecules; form the bilayer of a cell membrane
12
Sum of all chemical reactions that occur in an organism
14
RNA involved in protein synthesis; transfers a specific amino acid to the ribosome and binds it to the mRNA
15
Nitrogenous base that bonds with guanine
16
_____ transport chain is the part of cellular respiration that produces the greatest amount of ATP
20
Process during protein synthesis in which the DNA molecule is used as a template to form mRNA
21
Within the biologic hierarchic system of organization, this branch is the least inclusive
22
Type of cell with a membrane enclosed nucleus and a series of membrane organelles that carry out the functions of the cell
25
Organelles that read the RNA produced in the nucleus and translate the genetic instructions to produce proteins
27
Stage in mitosis where all chromosomes align along the metaphase plate (center of the cell)
28
Endoplasmic reticulum covered with ribosomes responsible for protein synthesis and membrane production
29
Stage of mitosis where the chromosomes are visibly separate with two noticeable sister chromatids
