The genetic makeup of an organism constitutes its genotype.
An allele that is always fully expressed is referred to as recessive.
An organism with two different alleles for a single trait is said to be heterozygous for that trait
Alleles are alternative forms of a gene.
The expressed physical traits of an organism are called its phenotype.
The cell grows
A copy of DNA is made (DNA duplicates)
The cell cytoplasm divides
All of the above are correct
A and B are correct, but not C
It plays an important role in proper development.
Many cancers begin because of problems associated with gene regulation.
Although complex, researchers have an excellent understanding of gene regulation.
It is the process that controls gene expression.
A molecule necessary to make copies of a gene.
The point where sister chromatids are attached together.
A structure where proteins are assembled together.
An enzyme that unzips a DNA molecule.
None of the above.
It occurs when many genes influence one characteristic.
It tends to affect males much more than females.
It produces phenotypes that tend to vary along a continuum.
It works when the effects of many genes add together to produce a particular phenotype.
It is also called polygenic inheritance.
They separate from each other during Meiosis I.
They segregate independent of each other during gamete formation.
They carry the same alleles.
They carry the same genes.
Proper reading of these sequences relies on molecules of tRNA.
Every gene is designated by these sequences.
They are nucleotide sequences that either start or stop transcription at that location on the molecule of DNA
They lie on either side of a coding sequence along a molecule of DNA.
Nucteotides.... . .amino acid
Polypeptides.... . .amino acid
Amino acids...... protein
Cell division is how old or damaged cells are replaced.
Cell division is the process that enables organisms to grow.
Cell division only occurs in cells of that produce eggs and sperm.
Ell division is the process during which the DNA is copied and the cell is split into two daughter cells.
It is a particular sequence of nucleotides found in a particular location along the molecule of DNA.
It can exist in alternative forms.
It contains the directions for the manufacture of a particular protein.
It is always expressed in the individual who has it.
It is copied during transcription.
The sequence of the different nucleotides along the length of the molecule.
The sequence of amino^acids that run along its backbone.
He type of sugars it possesses.
The total number of nucleotides it contains.
Useful for understanding the process of DNA replication.
A type of cell found only in plants.
Unspecialized, undifferentiated cells.
Important for directing natural selection.
None of the above
The baby is theirs, since the blood types of parents have no relation to their children's blood types.
The eggs must have been accidentally switched, since the baby's blood type has to match one of his parents.
Each parent could have contributed one recessive allele, resulting in type O blood.
The eggs must have been accidentally switched, since a type A parent and a type B parent can have any type children except O.
It is possible for the baby to have type O blood, since type O is inherited through a dominant allele.
Color blindness often appears randomly, even if neither parent is color-blind.
Since color blindness is recessive, both parents can pass it on, even if neither is color-blind.
the baby's father must have a recessive allele for color blindness.
Since color blindness is sex-linked, a son can inherit color blindness if his mother carries the recessive color blindness allele.
The eggs must have been accidentally switched, since males inherit sex-linked traits only from their fathers.
