Vocabulary
An abbreviation for deoxyribonucleic acid, which ia the genetic code material passed from parent to offspring.
What is DNA?
First discovered DNA, named it nuclien.
Who is Friedrich Miesher?
Prophase, Metaphase, Anaphase, and Telophase.(PMAT)
What are the four steps to Mitosis?
In this phase of meiosis chromosomes pair and cross-over occurs.
What is Meiosis 1 - Phase 1?
A shape that looks like a twisted ladder.
What is a double helix?
Two identical copies of the same chromosomes.
What is a sister chromatid?
Studied DNA using special x-rays.
Who is Maurice Wilkins?
In this phase chromosomes attached to the spindle fibers at the centromere and line up in the equator of the cell.
What is metaphase?
Type of cell meiosis is responsible for creating.
What are gametes?
A segment of DNA that codes for a trait and is transferred from parent to offspring.
What is a gene?
A complex of nucleic acids and proteins that make up chromosomes.
What is chromatin?
First photo of DNA, which helped confirm DNA's structure.
Who was Rosalind Franklin?
In this phase, new nuclear membrane forms. Spindle fibers dissapear. DNA returns to thread like form called chromatin.
What is prophase?
In this stage of meiosis there are four complete daughter cells (haploids) each different from other and different from the parent cell.
What is the meiosis 2 - telophase 2 stage?
Sugar molecules (deoxyribose) and phosphate molecules.
What is the backbone of DNA?
Four cells as a result of meiosis which are genetically from each other and the parent cell.
What are haploid cells?
Confirmed the three-dimensional structure of DNA.
Who are James Watson and Francis Crick?
In this phase, sister chromatids are pulled apart by spindle fibers. Separated chromosomes are pulled to opposite end of the cell.
What is anaphase?
There are two cycles of this, one in meiosis 1 and one in meiosis 2.
What is cell division?
A structure in the nucleus of an eukaryotic cell that is made up of DNA wrapped around histones (proteins)
What is a chromosoms?
An Abbreviation for ribonucleic acid, which is a type of nucleic acid that plays a role in making proteins.
What is RNA?
The division of the parent cells into two identical daughter cells.
What is Cytokinesis?
In this stage the chromosomes line up in the center in pairs.
What is meiosis 1 - metaphase 1?
Here there are four nitrogen bases: thymine, adenine, cytosine, and guanine
What are the rungs of DNA?
