Degeneracy
Degeneracy indicates that several codons can encode for the same amino acid during the process of protein synthesis from DNA. A codon comprises a triplet of <span>nucleotides that represents a specific amino acid.
This redundancy means that mutations (like point mutations) are less likely to disrupt the synthesis of proteins. For instance, if the codon sequence GAA, which represents glutamate, changes to GAG, glutamate will still be produced as the code is degenerate. </span>
Answer:
1. Insulin binds to the alpha subunit of the insulin receptor
2. Insulin receptor tyrosine kinase is activated
3. IRS proteins are phosphorylated
4. PDK1, a PIP3-dependent protein kinase, is activated
5. Phosphinositide 3-kinase (PI-3K) is phosphorylated
6. PIP2 is converted to PIP3
7. Akt is activated
8. Glut4 receptors are moved to the cell membrane
The OCCIPITAL LOBES of the CEREBRAL CORTEX play a crucial role in identifying fundamental elements of the visual environment. Known also as the visual cortex, these lobes are positioned at the rear of the skull.
