each parent must reduce his/her genetic material by half in a process called meiosis.

Asexual reproduction increases genetic variation-the raw material on which natural selection operates?
Asexual reproduction decreases genetic variation which is the raw material on which natural selection operates. This is because asexual reproduction produces identical offspring to the parent.
Sexual reproduction evolved before the evolution of?
Multicellular organisms
What happens to genetic information before a cell divides?
The genetic information is duplicated, so that each new cell has the same genetic code as the original.
What happens before messenger RNA is mature?
it attaches to RNA and the genetic code
What is the genetic material contained in each of the 46 chromosomes of a human cell just before division?
Each human cell contains 46 chromosomes. Just before division, these chromosomes contain two identical copies of all of the cell's genetic material.
Are joined strands of duplicated genetic material?
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
What is the difference between a bacteriaiophage and a prophage?
A bacteriophage is a completely assembled virus capable of landing on a bacterium and injecting it's genetic material in lysis, or a lysogenic attack. A provirus is a virus that has incorporated it's genetic material into the genetic material of the host for continual replication, thus, " before " the phage. This is the lysogenic phase of viral attack.
What must happen to the genetic material from each parent before sexual reproduction can occur?
The chromosomes from each parent sex cell must interact with each other in a process called crossing over. Crossing over allows the exchange of genes between the two chromosomes.
What is happening to the genetic material just before a cell leaves interphase and starts prophase of cell division?
replicating
What happens to the nuclear material of the parent cell before it divides?
Melios
What are 2 identical strands of genetic material?
Chromosomes and sister chromatids are joined strands of duplicated genetic material. A chromatid is one copy of a duplicated chromosome which, before replication, is composed of one DNA molecule.
What is the pathogen attacks specific cells and injects genetic materials?
Viruses attach specific cells and inject genetic material. There are viruses called bacteriophages that infect bacteria be injecting their genetic material into the bacterial host and invading their protein machinery. With animal viruses that infect animal cells (much larger than bacteria), the virus either injects genetic material OR gets into the cell whole before it begins to unleash its pathogenic effects
