BRCA1 and BRCA2 Genes

BRCA1 and BRCA2 Genes

Discuss how the primary structure of nucleic acids is the order of bases in the polynucleotide sequence, and the secondary structure is the three-dimensional conformation of the backbone.

Discuss how the primary structure of nucleic acids is the order of bases in the polynucleotide sequence, and the secondary structure is the three-dimensional conformation of the backbone.
Discuss the monomers of nucleic acids are nucleotides.
Discuss how the bases are bonded to the sugars, forming nucleosides.
Summarize how nucleosides are linked by ester bonds to phosphoric acid to form the phosphodiester backbone.
Specific proteins called single-strand binding proteins bind to the single-stranded regions and protect them from nucleases.
Spontaneous mutation of bases and insertion of the wrong nucleotide would normally lead to an error every 104 to 105

Instructions:

Step 1: Respond to the following:

Are the BRCA1 and BRCA2 genes reliable predictors of cancer and if so, should the person take the steps necessary to reduce their risk, such as a double mastectomy? Why/why not?

Answer preview discuss how the primary structure of nucleic acids is the order of bases in the polynucleotide sequence, and the secondary structure is the three-dimensional conformation of the backbone.
