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.
Smaller matches on the X will usually be too far back to find the relationship because the X chromosome does not get recombined when a father passes his only X chromosome on to make a daughter. Thus segments can stay together longer in time.
