PPT-Chromosomes Gene – segment of DNA that carries instructions for a specific trait

DNA in cells is usually spread out so transcription can take place During cell division chromosomes form Chromosomes are DNA and protein histones coiled into a rod After DNA replicates two . Camp Sunshine. July 22, 2013. Diamond . Blackfan. Anemia . Foundation. Diamond . Blackfan. Anemia Canada. THE FUNDAMENTALS. Humans have 46 chromosomes in each cell: 23 pairs. Sperm and egg cells have 23 chromosomes, 1 of each pair.. What is DNA?. DNA is where the GENETIC CODE is stored.. It is a set of instructions for building proteins. Sent by the CEO to the WORKERS as instructions for building PROTEINS. Who are the workers?. The RIBOSOMES. (Game from Univ. Utah). Siguna. Mueller. PhD student in BMS, Univ. Wyoming. What is DNA?. Each cell needs instructions for its role in the body. What do these instructions look like?. The instructions come in the form of a molecule called DNA.. Karyotypes. To find what makes us uniquely human, we have to explore the human genome. . A . genome. is the full set of genetic information that an organism carries in its DNA.. A study of any genome starts with chromosomes, the bundles of DNA and protein found in the nuclei of eukaryotic cells. . Chromosomes carry genes in a linear sequence that is shared by members of a species.. Understandings:. Prokaryotes have one chromosome consisting of a circular DNA molecule. . Some prokaryotes also have plasmids but eukaryotes do not. .. Alternate form of a gene. gene variant. autosome. Chromosome that does NOT determine sex. #1-22 in humans. chromosome. Structure made of DNA and special proteins; carries genes. DNA. Deoxyribonucleic acid;. GENES. DNA.

DNA damage DNA gets damaged a lot ! DNA damage DNA gets damaged a lot! >200,000 events/human cell/day DNA damage Occurs 2 ways 1) spontaneously 2) mutagens : damage DNA Transposons Discovered by Barbara McClintock Genetics Notes Who is Gregor Mendel? The law of Independent Assortment – Inheritance of one trait has no effect on the inheritance of another trait “ Father of Genetics ” Traits Genetics – study of how Gene cloning and other techniques, collectively termed DNA technology, can be used to manipulate and analyze DNA and to produce useful new products and organisms.. In genetic engineering, bacterial restriction enzymes are used to cut DNA molecules within short, specific nucleotide sequences (restriction sites), yielding a set of double-stranded DNA fragments with single stranded sticky ends..

These chromosomes are very long and thick in appearance during metaphase than normal chromosomes.. Hence they are called as Giant chromosomes.. The Giant chromosomes are of two types-. Deoxyribonucleic Acid (DNA). The DNA double helix structure was discovered in 1953 by James Watson and Francis Crick.. The DNA strands are made up of four nucleotides:. Adenine (A). Thymine (T). Guanine (G).
