What are the 3 parts of a DNA nucleotide? | -Sugar -Bases -Phosphate |
Adenine and Guanine | Purines |
Cytosine and Thymine | Pyrimidines |
Watson and Crick suggested what model of DNA? | Double Helix |
What are the nitrogen bases? | Adenine(A), Guanine(G), Cytosine(C), Thymine(T) |
The complementary base pairs. | C--G T--A |
The process of copying DNA in a cell is called _________. | Replication |
Structure of RNA | -Sugar (Ribose) -Phosphate -Base |
RNA is Different from DNA because..... | ....the sugar is ribose, thymine is NOT present (but uracil is), and RNA is single stranded. |
3 types of RNA | mRNA, tRNA, and rRNA |
mRNA | Messenger RNA |
tRNA | Transfer RNA |
rRNA | Ribosomal RNA |
Transcription | Process by which genetic information is copied from DNA to RNA. |
Protein Synthesis | The production of proteins. |
3 mRNA = ________ | A codon. |
Adenine and guanine are made of.... | ....two rings of carbon. |
Bases face toward... | ...the center. |
Bases bond to other bases of strands with what bond? | Hydrogen Bond |
Enzymes that bind to the separated chains of DNA. | DNA polymerase |
The process of assembling polypeptides from information encoded in mRNA is called what? | Translation |
Amino acids are transported to what? | Ribosomes |
Ribosomes are composed of what? | Proteins and rRNA |
The assembly of a polypeptide begins when... | ...a ribosome attaches to the start codon on an mRNA transcript. |
The start codon pairs with what? | The anticodon on tRNA. |
Pairing causes the specific amino acid to... | ...attach to the previously translated amino acids. |
The chain of amino acids make what? | A protein. |
This process continues until.... | ....a stop codon is reached. |
DNA is made up of... | ...repeating subunits of nucleotides. |
DNA consists of 2 chains of... | ...nucleotides. |
