Chapter 10 Biology

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.
