Meiosis

I.A Background & Key Question(s) Rapid reproductions in muscles cells are needed because our muscles are constantly exposed to exercise and injury. In our muscles, Myoblast is the embryonic cells that mature and fuse together forming Myocytes. Through the process myogenesis, Myocytes form muscles. However, specifically satellite cells aid in new growth and regenerated muscle. Since these cells respond to one another and create a domino effect they were used in this experiment. Rozwadowska et al…

It results when a boy is born with at least one or more extra X chromosomes. More than one extra is very rare.(3) The chromosomal change happens randomly during the process called Meiosis, the formation of new cells. The error is called a nondisjunction. The egg or sperm gains an extra copy of the X chromosome. If a male has more than one extra X chromosome, health problems can be at risk.(4) Half of the time, the extra X chromosome…

Day 1: Teacher will provide printed, fill in the blank Cornell notes, which include the warm up. For students needing accommodations they may staple the worksheet to their journal page to write on. Students who do not need accommodations may draw lines in their journal to make two columns needed to replicate the Cornell notes. Warm up: Write some of your physical traits. Example: Eye color. Teacher will review the warm up with the students. The teacher will choose a few students to share their…

white eyes, mini wings and yellow body with no stripes).We looked for the inheritance of the single trait. Thus, the monohybrid cross match with Mendelian law of segregation because it states that an allele for a single trait must be separate during meiosis into gametes. The monohybrid cross shows an autosomal inheritance due to the 3:1 ratio, ¾ wild type and ¼ apterous in the 1st generation (F1). Our null hypotheses for the monohybrid cross states there will be no significant difference…

Speciation is a process in which organisms within a population evolve to become a new species over time. Charles Darwin believed that eventually a single species will split off into two different populations, becoming two new species. Some of the speciation modes are allopatric and sympatric, and polyploidy is a mechanism of speciation. Allopatric Speciation Allopatric speciation is a common mode of speciation in which a population of a single species becomes divided, geographically isolating…

Genome Evolution Did you know that the Tasmanian Devil’s genome is rapidly evolving to resist a deadly disease that has killed eighty percent of their population since 1996? To most people that means little to nothing, because most people don’t know what a genome is let alone the process in which it takes to evolve or for Scientists to discover the evolution. In the following paragraphs we will discuss what genome evolution is, how genomes are able to be compared and how the size can…

Introduction The common name of the Vulpes vulpes is the red fox. The red fox has a relatively long body with dense fur. The fur is typically a rusty red color and the legs are darker in color, sometimes even black. Foxes have black pointed ears and long canine teeth. On their underside, the fur is white from their nose down to their belly, orangish-red fur on its back, sides, and head. Red foxes have white fur under their neck and on their chest. A male fox, also called a “dog” weighs…

In protein synthesis there are 3 to 4 structures that occur. In the primary structure there are covalently bonded sequences of amino acids and this happens through dehydration synthesis where complex molecules are broken down to simple components. Secondary structure happens within the protein and can repeat multiple times and this happens from the folds by the Hydrogen bonds. Finally, you reach tertiary structure where the final 3-dimensional shape is shown by the complete polypeptide chain.…

BACTERIAL TRANSFORMATION By Derek Tang BIO 281 Lab section 80243 Abstract: The objective of this experiment was to observe the results of bacterial transformation in various growth conditions and determine how successful the altered organism is after the transformation. The organism used was E. Coli because singular cell organisms can have a new gene more easily inserted than multi-cellular organisms. The gene which was inserted is pGLO that carried the gene encoding GFP and a gene for…

chromosome in their cells. Though this may seem like a minimal change beyond the norm, these are the instructions for how the body should develop and if anything is thrown off balance it could result in extreme anomalies. During a process called meiosis, a type of cell division, a sperm or egg may experience a critical error called nondisjunction where the sex chromosomes do not split correctly. When nondisjunction occurs, the sperm or egg will have an extra chromosome which will then be…
