4 thoughts on âGolf Carts: Fairway or Rough?â. Iâve heard that the issue is the grass type, rather than the generic fairway or rough. Apparently carts do more damage to fescue (typically a rough grass) than typical fairway grass (whatever that may be). My club is almost exclusively walking, and our fairways and rough are both fescue. Where to drive is a source of controversy on the rare occasion a cart is used.
In addition, enzymes add methyl groups to the DNA of the inactive X, resulting in repression of transcription. The inactivated X is visible during interphase in mitosis as a condensed chromosome, called a Barr body. It replicates in the S (synthesis) phase of the cell cycle later than does the active copy. Inactivation of one of the two X copies in a female leaves only one active. X chromosome in any cell. An individual who has three X chromosomes has two inactivated copies of the X, producing two Barr bodies.
X-linked inheritance means that the gene causing the trait or the disorder is located on the X chromosome. Females have two X chromosomes; males have one X and one Y. Genes on the X chromosome can be recessive or dominant.Their expression in females and males is not the same.Genes on the Y chromosome do not exactly pair up with the genes on the X chromosome. X-linked recessive genes are expressed in females only if there are two copies of the gene (one on each X chromosome).heir expression in females and males is not the same.
