A __________ compares or shows the relationship between two quantities.
DNA
Clone
Meiosis
Ratio
A ________ is an organism, cell, or piece of genetic material that is genetically identical to the one from which it was derived.
DNA
Clone
Ratio
Meiosis
____________ is the process of cell division that results in the formation of cells with half the usual number of chromosomes.
DNA
Clone
Meiosis
asxual
The type of reproduction that results in offspring that are genetically ientical to the single parent is known as __________ reproduction.
DNA
Clone
Asexual
Meiosis
Sex-linked
codominance
complete dominance
incomplete domiance
What process dose a multicellcular organism use to replace its damaged body cells?
Mitosis
meiosis
replication
transcription
deletion
insertion
substitution
transcription
How does a sex cell differ from a body cell?
A sex cell does not contain chromosomes
A sex cell contains homologous chromosomes
A sex cell has the same number of chorosomes as a body cell.
A sex cell has half the amount of genetic material as body cell.
How do the chromosomes at the end of meiosis I compare with the chromosomes at the end of meiosis II?
Chromosomes have one chromatid at the end of both meiosis I and meiosis II
Chromosomes have two chromatids at the end of both meiosis I and meiosis II
Chromosomes have one chromatid at the end of meiosis I and two chromatids at the end of meiosis II
Chromosomes have two chromatids at the end of meiosis I and one chromatid at the end of meiosis II
A pair only with C, and T pairs only with G
A pairs only with T, and C pairs only with G
DNA is amde up of nuclrotides that consist of a sugar, a phosphate, and a base
The bases i DNA are arranged in the interior of a double helix, like rungs of a ladder
Which of the following is an advantage of asexual reproduction?
It is a slow process
Two parents are needed
The organism can increase in number quickly
It introduces genetic diversity in the offspring
As a codominant trait
As a recessive trait
As a dominant trait
As an incompletely dominant trait
Which of the following statements correctly describes the function of cell division in unicellular organisms?
Cell division allows the organism to grow
Cell division allows the organism to reproduce
Cell division allows the organism to produce sex cells
Cell division allows the organism to repair damage to the cell
Which statement about zygotes, which form by fertilization, is correct?
Zygotes have a full set of chromosomes, receiving half from each parent.
Zygotes have half the set of chromosomes from one parent only
Zygotes have two full sets of chromosomes, one set from each parent
Zygotes have half the set of chromosomes, one-fourth fro each parent
Each chromosome would still have two chromatids
The Chromosomes would look the same as in mitosis
You would be able to see DNA in the chromosomes during meiosis
Homologous chromosomes would be moving to the same end of the cell
If the sequence of bases in one strand of DNA is ATTCGAC, what will be the base sequence on the strand that is formed during replication?
ATTCGAC
TAAGCTG
UAAGCUG
AUUCGAC
