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.
A small, condensed mass of the inactivated X-chromosome usually located just inside the nuclear membrane of the interphase nucleus; the number of sex chromatin bodies per nucleus is one less than the number of X-chromosomes; hence, normal males have none and normal females have one.he substance of the chromosomes, composed of DNA and basic proteins (histones), the material in the nucleus that stains with basic dyes. sex chromatin the persistent mass of the material of the inactivated X chromosome in cells of normal females; called also Barr body.
