DNA structure
and function
and function
DNA is defined as this
What is the instructions for life?
The number of parents needed for asexual reproduction
What is one parent?
The phase of the cell cycle where cells spend most of their time (normal cell living)
What is interphase?
A haploid, reproductive cell (could be male or female)
What is a gamete?
The phase that proceeds both meiosis and mitosis
What is interphase?
This is the location in the cell where DNA is found
What is the nucleus?
This is an organism that is genetically identical to it's parent organism.
What is a clone?
In this stage of mitosis, chromosomes line up across the middle of the cell
What is metaphase?
When a male and female gamete fuse to form a zygote
What is fertilization?
This event happens during prophase I and contributes to genetic diversity of gametes
What is crossing over?
The sequence of these four DNA bases determines what proteins and molecules the cell will make.
What are adenine, thymine, cytosine and guanine?
Five asexual reproduction strategies
What are budding, fragmentation, vegetative propagation, spore formation, and binary fission?
Things that happen during prophase?
What is formation of the spindle apparatus, dissolving the nuclear membrane, condensation of chromatin into chromosomes?
Forces that plants rely on for sexual reproduction
What are wind and pollinators?
In anaphase I, these are pulled to opposite poles of the dividing cell
What are homologous chromosomes?
The DNA back bone is made of these two substances
What are sugar and phosphate?
The main advantage of asexual reproduction
Four things that the cell does during interphase
What is growth, duplication of organelles, duplication of DNA, and checking DNA for damage?
The two types of sexual reproduction
What are internal and external fertilization?
In anaphase II, these are pulled to opposite sides of the dividing cell
What are sister chromatids?
From least to most coiled, these are the three levels of DNA structure
What is the DNA double helix, chromatin, and chromosomes?
What are prokaryotes (bacteria and archaea)?
The result of mitosis
What are two genetically identical, diploid, daughter cells?
A new organisms first somatic cell; a diploid cell that will divide to form the embryo and, eventually, all other cells in our body.
What is a zygote?
The result of meiosis
What are four genetically unique, haploid daughter cells?
