nucleotides | sugar, phosphate, and base |
Adenine and Guanine | Purines |
Cytosine and Thymine | Pyrimidine's |
The process of copying DNA in a cell is called | Replication |
Structure of RNA | repeating units |
Differs from DNA | sugar is ribose, thymine is not present, RNA is single stranded |
Types of DNA? | mRNA, tRNA, rRNA |
Transcription | process by which genetic information is copied from DNA to RNA |
Protein Synthesis | the production of proteins |
Genetic Code | a correlation between a nucleotide sequence and an amino acid sequence |
3 mRNA nucleotides | codon |
Start codon | AUG |
Stop codon | UAA, UAG, UGA |
Translation | The process of assembling polypeptides from information encoded in mRNA |
Anticodon | the loop opposite of the site of amino acid attachment bears a sequence of three nucleotides |
Ribosomes | are composed of rRNA and proteins and are free in the cytoplasm and attached to the endoplasmic reticulum |
Double Helix | bases face toward the center and face the base of other chains with which they form hydrogen bonds. |
Deoxyribose | five-carbon sugar in a DNA nucleotide |
Nitrogenous base | an organic base that contains nitrogen, and subunit of nucleotide in a DNA and RNA |
Purine | Nitrogenous bases that have a double ring of carbon and nitrogen atoms such as adenine and guanine. |
Pyrimidine | Nitrogenous bases that have a single ting of carbon and nitrogen atoms such as cytosine an thymine |
base-paring rules | the rules stating that cytosine pairs with guanine and adenine pairs with the thymine in DNA |
Complementary base pairs | cytosine on one strand pairs with guanine on the opposite strand, and thymine |
base sequence | The order of nitrogenous bases on a chain of DNA |
DNA replication | is the process by which DNA is copied in a cell before a cell divides by mitosis, meiosis, or binary fission. |
Helicase | An enzyme that separates DNA strands |
Replication fork | Y-shaped point that results when two strands of DNA |
DNA polymerase | An enzyme that catalyzes the formation of DNA molecule |
semi-conservative replication | In each new DNA double helix, one strand is from the original molecule, and one strand is new |
Mutation | A change in he nucleotide \-base sequence od a gene or DNA molecule |
