Down syndrome is also defined as a birth condition that is experienced by individuals who are born with an extra copy of chromosome 21. Individuals who experience this condition tend to experience different physical issues and intellectual disabilities as well. People who are born with Down syndrome are usually unique in a way and may have different healthcare conditions. Some of

Cell Cycle Describe how major events of cell division that enable the genome of one cell to be passed on to two daughter cells. List the phases of cell cycle and describe the sequence of events that occurs during each phase. There are two main stages of the cell cycle‚ with multiple subdivisions within each. Interphase is the first stage‚ and it’s composed of G1 (contents of the cell are duplicated sans the chromosomes)‚ S (chromosomal duplication)‚ and G2 (checkpoints) phase. After interphase‚

The chromosome is composed of two main molecules. a) DNA b) Proteins called histones. This image was taken shortly after DNA a replication but before the prophase. It is composed of two daughter chromatids joined at the centromere. The chromosome is super coiled by a factor around x16‚000. The DNA molecule is about 1

separated equally this is known as non-disjunction in males meiosis I accounts for 80% of cases this is where gametes end up with either an extra chromatid or no chromatid. With Down syndrome the offspring carries an extra chromatid in Chromosome 21 which is Trisomy 21. You have Turner syndrome which is one of the three most common chromosome abnormalities found in first trimester they often have extensive edema which results in neck webbing and arched nails and usually have heart defects and kidney malformation

This disorder is called Down Syndrome and it affects over 200‚000 children a year‚ it is also known as trisomy 21. Down Syndrome is a genetic disorder caused by 3 chromosomes in your 21st pair of chromosomes. Children with Down Syndrome need extra attention and have special teachers in school to help them. There are many different struggles that children with

Triple X syndrome‚ also known by alternative names such as Trisomy X or Triplo X‚ is a disorder within chromosomes. Our bodies are composed of millions of cells and each cell contains 46 chromosomes inside of its nuclei‚ which acts as the "brain" for the individual cell. Of these chromosomes there are typically 2 sex chromosomes‚ if you are female you will have two X chromosomes‚ and if you are male you will have one X chromosome and one Y chromosome. When someone is diagnosed as having Triple

false impression that pregnancy screening has eliminated or substantially reduced the incidence of Down syndrome in the population. Despite years of screening‚ the Down syndrome population in the country has remained stable. Down syndrome‚ or Trisomy 21‚ as it is called within the medical community‚ is caused by an extra copy of the 21st chromosome. An error in cell division‚ called non-disjunction‚ happens at the moment of conception for reasons we still do not understand. The extra chromosome
