DNA
The building blocks of DNA.
What are nucleotides?
The process is called fertilization.
What is it called when a sperm cell and egg combine?
Two cells that are identical to each other and to the parent cell.
How many daughter cells are produced when a bacterial cell reproduces asexually?
It happens after Metaphase.
When does Anaphase happen in Mitosis?
The phase where the sister chromatids are separated from each other.
What is Anaphase II?
Special proteins surround DNA and form chromatin.
What are histones?
A case where the offsprings are identical to each other.
What are twins?
Genetically identical cells.
What are clones?
Half of a chromosome.
What are chromatids?
The part of meiosis is most similar to mitosis.
What is meiosis II most similar to?
The nitrogenous bases that form in the double helix.
What are Adenine, Cytosine, Guanine, and Thymine?
A haploid cell
What is a cell with half the amount of chromosomes called?
Type of asexual reproduction by separation of the body into two new bodies.
What is binary fission?
Two nuclei form and each nucleus contain a copy of the cell's DNA.
What happens during Telophase?
During this stage of meiosis the DNA and chromatin condense into chromosomes .
What happens during prophase I of meiosis?
Make up the structure or backbone of DNA.
What do sugar and phosphate groups do?
It has half as many chromosomes as a body cell.
How many chromosomes does a gamete have when compared to a body cell?
The only source of variation in asexual reproduction.
What is mutation?
Duplicated chromosomes form an X-like shape.
What happens in Prophase?
Both of these cells undergo meiosis.
Do eggs cells undergo meiosis or do sperm cells?
They are proteins that help condense and pack the DNA inside the nuclei.
What are histones?
A gamete.
What is a reproductive, haploid cell that carries one copy of chromosomes?
Gametes are not needed for asexual reproduction because...
There is no cell division by meiosis.
The phase where the cytoplasm divides into two daughter cells.
What is Cytokinesis?
Crossing over happens during this phase.
What happens during prophase 1?
