JAMES WATSON AND FRANCIS CRICK
Broke the code of DNA structure in 1953 by gathering information from fellow scientists
WHO DID THEY GATHER INFO FROM?
Line Pauling, Maurice Wilkins, and Rosalind Franklin
MAURICE WILKINS AND ROSALIND FRANKLIN
X-ra picture of DNA
STRUCTURE OF DNA
phosphate attached to a sugar group
genetic material made of nucleotide sequences
4 TYPES OF DNA
Guanine, Cytosine, Adenine, and Thymine
WHICH OF THESE DNA'S PAIR UP?
Guanine + Cytosine
Adenine + Thymine
An organisms full set of DNA found in its nucleus or in circular pieces of genetic material
HOW MANY PAIRS OF CHROMOSOMES TO HUMANS HAVE?
EACH SPECIES WILL HAVE THE SAME AMOUNT OF CHROMOSOMES THAT MAKE UP GENETIC MATERIAL?
LARGER NUMBER OF CHROMOSOMES MEANS MORE COMPLEX ORGANISM?
Genes are the specific sequence of base pairs that carry the information for a specific product or expression
Alternate versions of a gene that code for the same feature. pair of genes for a given trait.
Regions of the gene that are considered "non-coding" DNA sequences. They will usually precede and follow after.
Coding sequence of the gene.
ARE THERE MORE CODING SEQUENCES THAN NON-CODING SEQUENCES?
The sequence of base pairs that codes for a particular trait or protein for the organism
The physical trait or protein made by the gene.
WHAT MUST OCCUR FOR THE BASE PAIR SEQUENCE'S "MESSAGE" TO GET OUT IN TO THE CELL?
Translation and Transcription
makes an mRNA strand of one side of the DNA
mRNA is translate into two DNA strands
Can leave the nucleus and work its way to a ribosome for protein production
WHEN DOES TRANSLATION OCCUR?
After mRNA has found its way from the nucleus to a ribosome
Decode into strands of proteins that are very long chains of amino acids
A series of 3 nucleotides that reads a 3 nucleotide sequence in the mRNA in order to find the amino acid that will be next in line for the protein to be built.
