Termination efficiency can vary from 2% to 90%, Point mutations reduce termination efficiency usually occur within the stem region of the hairpin, replacing GC base pairs with weaker AT base pairs

PTEN can remove phosphate groups attached to serine,

threonine, and tyrosine residues in proteins, its ability to

remove the 3-phosphate from PI(3,4,5)P3 is its major function in cells.

Autosomal Recessive Traits

Autosomal recessive traits normally appear with equal frequency in both sexes.

The trait seems to skip generations.

When both parents are heterozygous, approximately one-fourth of the offspring are expected to express the trait.

Recessive traits appear more frequently among the offspring of consanguineous matings.

Example - Tay–Sachs disease, sickle cell anemia, cystic fibrosis, PKU
