Term | Definition |
Genes | Units of genetic material that codes for a specific trait |
DNA and RNA are examples of | Nucleic Acids |
DNA is made up of | Repeating molecules called Nucleotides (building blocks) |
Nucleotide consists of three different structures | 1) Phosphate group
2) Sugar Deoxyribose
3) Nitrogenous Base |
DNA Structure | Is called DOUBLE HELIX |
DOUBLE HELIX was discovered by 3 scientist | 1)Fredrick Griffith
2) Rosalind Franklin
3) Watson and Crick |
DNA had specific pairing between nitrogen Bases | Adenine... Thymine
Cytosine....Guanine |
DNA is made of 2 long strands of Nucleotides arranged in a specific way | Complementary Rule |
Purines: | Adenine
Guanine |
Pyrimidine's | Thymine
Cytosine |
Adenine must pair with | Thymine |
Guanine must pair with | Cytosine |
Different arrangements of Nucleotides in a nucleic acid DNA provides | Key to DIVERSITY among living organism |
The Code of the Chromosome | the specific order that bases occur. |
Chromosomes | DNA is wrapped tightly around histones and coiled tightly |
DNA is replicated to prepare for a cell division | During phase of a cell lifecycle. |
Nucleus of the cell occurs during | DNA replication |
Template | Each strand of the original DNA serves as a template for the new strand. |
DNA Molecule | Will produce 2 identical new complementary strands at the completion of DNA replication. |
Enzyme Helicase | Breaks the hydrogen bonds connecting the complimentary bases of the original DNA molecule. |
Enzyme DNA Polymerase | binds the new nucleotides to the original strand and proof reads for mistakes in pairing |
Helicase is doing this | The DNA molecule and allows for new complimentary nucleotides to match up with the nucleotides of the original template |
