DNA Structure
DNA stands for
Deoxyribose nucleic acid
What does RNA stand for ?
Ribose nucleic acids
During mitosis 1 parent cell becomes how many daughter cells
2
How many cells are the result of Meiosis?
4
A nucleic acid is made from a base, a ribose sugar and a what?
phosphate molecule
How does DNA replicate from one strand of DNA
DNA is unzipped and free nucleic acids bind to their complementary base pairings.
What phase comes after prophase?
Metaphase
What is the name of the cells that are formed from the process of meiosis?
Gametes
Whats is the human genome?
All the genes that are found in your DNA
In which phase of the cell cycle does DNA replication occur?
Interphase
What occurs during Telephase?
The cell divides into 2 daughter cells which are genetically identical
How many phases does meiosis have?
9
IPMAT
PMAT
Where in the cell is DNA found?
The nucleus
What do genes code for?
Proteins
During which phase of mitosis do chromotids divide?
Anaphase
How many chromosomes does each cell have as a result of meiosis?
Adenine binds with what other base?
Thymine
How do mutations occur?
There becomes a mistake in the DNA sequence during replication or translations and therefore codes for a wrong protein.
How many chromosomes do the daughter cells have as a result of mitosis?
What does crossing over mean and when does it occur?
It occurs in Meiosis 1 and is when the chromosome pairs come together and swap some genes
