Cell Division & Reproduction
The creation of genetically identical offspring by a single parent, without the participation of sperm or egg.
What is asexual reproduction?
These structures, joined together at a centromere, separate into daughter cells during cell division.
What are sister chromatids?
These monomers of both DNA and RNA are composed of a sugar, a phosphate, and a nitrogenous base.
What are nucleotides?
In an organism that reproduces sexually, a cell containing two homologous sets (2n) of chromosomes, one from each parent.
What is diploid?
During this stage of mitosis, chromosomes line up on an imaginary plane that is between the two spindle poles.
What is metaphase?
One way that RNA differs from DNA is through the inclusion of this nucleotide.
What is uracil?
Any cell in a multicellular organism except a sperm or egg cell, or a cell that develops into a sperm or egg.
What is a somatic cell?
A structure found in animal cells from which microtubules originate. It is a critical structure for both mitosis and meiosis.
What is a centrosome?
This important feature of DNA allows the sequence of one strand to be predicted by the sequence of the other strand.
What is complimentary base pairing?
This process produces daughter cells with the same number of chromosomes as the parent cell.
What is mitosis?
During this phase of mitosis fragments of the nuclear envelope are still present, but the sister chromatids are not yet lined up.
What is prometaphase?
The double-ringed nucleotides from this category of molecules always pair with pyrimidines.
What are purines?
