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.
Answer by Farah ramadan. Confidence votes 43. A Barr body is the inactivated X chromosome that is usually found in the nuclei of female somatic cells. It can also occur in males when there is an abnormality and the male is XXY instead of the normal XY, a condition known as Klinefelter's syndrome. In this case, the male somatic cells would also contain a Barr body. ---.
