Isaac Asimov's science fiction novel "The Fun They Had" is a poignant and thought-provoking commentary on the impact of technology on society. The story follows a young girl named Margie as she becomes fascinated with a rare book that contains traditional, printed pages. In a world where all information is accessed through electronic screens and education is fully automated, Margie's discovery sparks a sense of nostalgia and longing for a different way of life.

As the story unfolds, Asimov presents a bleak vision of the future where the joy and curiosity of learning has been replaced by a sterile, efficient system that lacks humanity. Margie's teacher, Mrs. Jones, is a perfect example of this, as she is more concerned with meeting the quotas of the computerized curriculum than fostering a love of knowledge in her students.

Despite this, Margie remains determined to learn and understand the world around her. She is drawn to the physicality of the book, with its textured pages and musty smell, and she becomes engrossed in its contents. As she reads, Margie begins to realize that the world of the past was not perfect, but it was a place where people could express themselves and engage with each other in meaningful ways.

Asimov's portrayal of the future in "The Fun They Had" is a cautionary tale about the dangers of relying too heavily on technology. While it can certainly have its benefits, Asimov suggests that it is important to preserve the human element in education and society. Margie's love of reading and learning, despite the obstacles she faces, serves as a reminder of the joy and fulfillment that comes from intellectual curiosity and exploration.

In conclusion, "The Fun They Had" by Isaac Asimov is a thought-provoking exploration of the impact of technology on society. Through the character of Margie, Asimov reminds us of the importance of preserving the human element in education and the joy that comes from learning and engaging with the world around us.

Retrieved 6 December 2009. It took until 1954 before the human diploid number was confirmed as 46. And these stages are characterized by the breakdown of the nucleolus and nuclear envelope for proper cell division to take place. Yes, chromosomes are made up of genes.

In addition, chromosomes can be copied and moved into reproductive cells sperm and eggs so that genetic material passes from generation to generation. This site does not constitute any kind of pet medical advice, so please consult a licensed veterinarian in your area for pet medical advice. Answer and Explanation: 1. Each chromosome is made up of a single supercoiled DNA molecule packaged with histone proteins. The spindle apparatus has things known as microtubules and motor proteins which are utilized to pull the chromosomes apart and shift them to the correct positions.

This also shows that the chromosome is a part of DNA. Octodrilus complanatus Annelida: Oligochaeta: Lumbricidae , revealed by single- and double-color FISH". Chromosomes are made of strands of DNA wrapped around spools of protein called histones and organized into distinct packets. The technique of determining the karyotype is usually called karyotyping. Abnormal numbers of chromosomes typically result due to the failure of homologous chromosomes to be properly separated during cellular division.

Packaging of the DNA molecule into chromatin allows for the cell divisions like mitosis and meiosis to take place by preventing chromosome breakage. Chromosomes are also critical for cells to be able to make new copies of themselves and for life's instructions to be passed down from one generation to the next. These daughter cells with half the number of chromosomes are referred to as haploid cells. This means that the chromosome number will be half the number of chromosomes in the parent cell, contrasted with mitosis where the chromosome number in the daughter cells remains the same as the parent cell. The X chromosome does much more than turn an embryo into a biological male.

When a cell is ready to split into two cells, it first copies its chromosomes. For example, people with Turner syndrome have 45 chromosomes, having a single X chromosome rather than a pair of Xs or an X and Y. A gene is just only a section of a DNA molecule, and a chromosome contains hundreds to thousands of genes. Bethesda, Maryland: National Center for Biotechnology Information. Is a chromosome part of DNA? A chromosome is circular in the case of prokaryotes. DNA molecule is so long that it can have both coding and non-coding DNA sequence.

But it does have one important gene SRY that causes most Y- containing embryos to develop as biologically male. The spermatogenesis of man". Proceedings of the National Academy of Sciences of the United States of America. Structure And Function Of The Chromosome Chromosomes are aggregated collections of genes, made out of tightly wound packets of chromatin, which are themselves composed out of proteins and DNA. The structure of the nuclear envelope helps the nucleus maintain its shape and assists the nucleus in controlling which molecules move in and out of it.

During the late Prophase, sometimes referred to as Pro-metaphase, the mitotic spindle stretches out and captures the chromosomes within it. Where in a human cell the chromosomes are located depends on when you look. The genes on each chromosome are arranged in a particular sequence, and each gene has a particular location on the chromosome called its locus. A chromosome is formed when the DNA double helix structure condenses and wraps around 8 histone proteins forming a nucleosome. The growth of biological thought.
