Cell Division
oncologist
cancer researcher
A cell surrounded by a protective covering
spore
A double-sided chain that looks like a twisted ladder
DNA
The process of putting amino acids together in a specific sequence
protein synthesis
In this phase of mitosis, all the chromosomes are lined up at the center of the spindle
metaphase
Before a cell divides, it makes a copy of its genes during this stage
interphase
This process takes place through the process of cell division - regrowing missing body parts
regeneration
The basic unit of DNA and RNA, consisting of sugar, a phosphate, and a base
nucleotide
The process of forming mRNA from DNA
transcription
These cells may go through mitotic cell division several times a day
human skin cells
The three stages of cell division
interphase mitosis cytokinesis
The number of cells present at the end of meiosis
four
A group of three nucleotides
codon
This carries the genetic code from the DNA to the ribosomes
messenger DNA
The division of a cell's cytoplasm and organelles
cytokinesis
When all the genes of a chromosome have duplicated but are still attached, these structures are formed
sister chromatids
Through this process sexual reproduction copies genetic reproduction
meiosis
The four bases of DNA
adenine thymine cytosine guanine
Protein synthesis occurs in this organelle
ribosome
It is unimportant that each cell gets exactly the same amount of cytoplasm and the same number of these in cell division
organelles
The four phases of mitosis
prophase metaphase anaphase telophase
reproduction by mitotic cell divisions
asexual reproduction
In the DNA molecule, name the pairs of bases
thymine - adenine
guanine - cytosine
In the RNA molecule, name the pairs of bases
uracil - adenine
guanine - cytosine
This type of molecule never contains the code for the sequence of amino acids needed to manufacture a protein
tRNA
