22. Which process produces identical new cells — mitosis, meiosis, or both? Also can be used at classroom in subjects related to Genetics or Bioinformatic presentations. Translocation: One part of a chromosome is transported to another chromosome, or an entire chromosome attaches to another chromosome (Robertsonian translocation). Chromosome walking is a method of positional cloning used to find, isolate, and clone a particular allele in a gene library.An allele is a gene for a particular genetic trait passed on from adults to their offspring, such as the allele for brown eyes in a gene for eye color. Genes are the individual instructions that tell our bodies how to develop and keep our bodies running healthy. You can change your ad preferences anytime.

It is important that we have the correct amount of chromosome material, as the genes (that instruct the cells in our body) are found on the chromosomes. While metaphase chromosomes can be depicted as distinct bodies with well-defined shapes and sizes, interphase chromosomes are less uniform and, by filling the nuclear space, difficult to distinguish. The picture above therefore shows the chromosomes of a male as the last pair of chromosomes are XY. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Each chromosome has a centromere, which divides the chromosome into two uneven sections. It is a single piece of coiled DNA containing many genes, regulatory and other nucleotide sequences.

Different isolates of the same species often have a different chromosome number, with some of these additional chromosomes being unnecessary for normal growth in culture. In every cell of our body there are 20,000 to 25,000* genes that are located on 46 chromosomes. Chromosome polymorphisms are very common among fungi. Explain how many of each is present in a gamete and in a somatic cell.
