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 Barr body represents an inactive X chromosome in a femaleâs somatic cell. Barr bodies are small, dark stained mass of inactive X-chromosomes in females within the nucleus. Mc.Barrâ and âBertram were the two scientists to observe the deeply stained chromatin body in the nerve cell of female cat in the year 1943.
