what does the nucleus do?
its the control center

What is heredity
The passing of traits from parent to offspring.
100
What is genetics
The scientific study of heredity is also called this
100
What is homozygous
Purebred means the same as this
100
What is hybrid or heterozygous
when two things are different
200
true or false.. is nucleus inside cells
true
200
What are Alleles
These are different forms of a gene
200
What is a dominant allele
A trait that will ALWAYS show up in an organism as long as it it present
200
What is a recessive allele
A trait that is masked by a dominant allele
200
What is a Karyotype
This is a chart that shows and arranges chromosomes in order from largest to smallest
300
Is there a nucleus in an animal cell?
yes.
300
What is a Phenotype
Relates to physical characteristics
300
What is a Punnett Square
This is a chart used to find all possible allele combinations in a cross
300
alleles for a trait What is heterozygous
alleles for a trait
300
This is having two IDENTICAL alleles for a traitWhat is homozygous
This is having two IDENTICAL alleles for a trai
400
How many cells make up your body?
37 trillion
400
What is DNA
Referred to as the "genetic blueprint" or code for an organism
400
What is mRNA
This brings the code from the nucleus to the ribosome
400
What is tRNA
This translates the message, and collects amino acids
400
What is a mutation
This is a permanent change in an organisms DNA
500
two parts of the cell that hold DNA
Mitochondria and nucleus
500
What is a protien
Amino acids arranged in a particular order produce a certain one of these
500
What is an example of two recessive traits being carried and passed by both parents
When a child shows traits that neither of the parents show
500
What are stem cells
This has to do with cells that do not have a specific function, and can therefore become any type of cell. Research in this area is very controversial
500
What is genetic engineering
An example of this would be creating "super rice" or transferring genes from one organism to another
