Mitosis/Meiosis

QuestionAnswer
What is the shape of DNA? Spiral staircase
Name the 4 bases found in DNA. Adenine, Thymine, Guanine, and Cytosine
Adenine always pairs with ____________ in DNA. Thymine (Apples in the Tree)
Cytosine always pairs with ___________ in DNA. Guanine (Cars in the Garage)
What is the function of DNA? It carries all our genetic information
In DNA, the sugar is deoxyribose. What is the sugar in RNA? Ribose
DNA is double stranded. RNA is _______ stranded. Single
In DNA, adenine pairs with thymine. In RNA, adenine pairs with ___________. Uracil
What do we call the type of cell division where a cell makes an exact copy of itself? Mitosis
Mitosis makes all the cells in our bodies except for ____________ cells. sex (sperm and egg)
Human beings have _____________ chromosomes. 46
DNA replication occurs during what part of the cell cycle? Interphase
Has the genetic material formed an "X" yet during interphase? NO!
What happens during prophase? Chromosomes appear. Nuclear membrane dissolves.
What happens during metaphase? Chromosomes line up at the center.
What happens during anaphase? Chromosomes split and move to opposite ends of the cell
What happens during telophase? New nuclear membranes form. Cell starts in pinch in a bit
What happens during cytokinesis? Separation into 2 cells.
A _________________ is any change that occurs in a gene or chromosome during replication. Mutation
True/False: ALL mutations are harmful. FALSE
What is the name of the cell process that creates cells with 1/2 the genetic information? (sperm and egg cells) Meiosis
Why is it necessary to create cells with 1/2 our genetic information? Because we get half of our genetic info from our moms and half from our dads. That is why we resemble both parents without being a copy of either parent.
Who discovered DNA in 1953? Watson and Crick
Where in the cell is the DNA located? the nucleus
Our bodies need mitosis for GROWTH AND REPAIR
How are mitosis and meiosis the same? They both create new cells
How are mitosis and meiosis different? Mitosis creates exact copies. Meiosis creates copies with 1/2 the genetic information
