Eat your vegetables, before they eat you! This week we will be learning about genetics. Earlier we learned about traits and characteristics and how they affect the appearance of an organism. This week we will be focusing on inherited traits, genes and alleles. We will also be setting up an experiment that shows how these inherited traits are passed from parent to offspring in plants! KEY WORDS Inherited Traits- An inherited trait is a characteristic passed from parents to the offspring or child through genes. Genes- The basic unit of heredity. Different forms of genes are called alleles. Alleles- Alternative form of a gene inherited separately from each parent. (for eye color the allele might result in blue or brown eyes). KEY CONCEPT: All organisms have genes and inherited traits. You have 3 tasks to accomplish for this week's BLOG. A. Read the article (use the link) and answer the following questions in complete thoughts. 1. What are inherited traits? 2. How many pairs of chromosomes are found in a human cell? How many genes? 3. How do you know if you have a recessive trait? B. Watch the video (use the link) and answer the following questions in complete thoughts. 1. What is the structure & function of chromosomes? 2. What is the difference between a body cell and a sex cell? 3. How do people get Down's Syndrome? C. Watch the video (use the link) and answer the following questions in complete thoughts. 1. Genes are part of what? 2. Explain how genes are like family recipes? 2. How many chromosomes do the following organisms have:
*If you have time watch genetics 101, part 2 and tell me what SNP's are? |

Core B, Micro-life, Week 6
You have 3 tasks to complete for this week's BLOG. Copy the blog into a word document and save it before you begin!
A. Read the article below and describe 3 ways antibiotics work to stop infections and explain the 3 risk factors associated with antibiotic use.
Antibiotics work by killing off or damaging the bacteria infecting the patient’s body. Infections can only take a strong-hold if the bacterium that causes them is allowed to reproduce. It is the rapid reproduction of bacteria that enables an infection to harm the body.
The antibiotic Penicillin interferes with the construction of bacterial cell walls during formation, allowing the bacteria’s organelles to leak out, which effectively kills the bacteria. Other forms of antibiotics actually poison bacterial components, destroying the proteins they need to reproduce. And yet other types of the drug interfere with the genetic code necessary for the bacteria to reproduce.
The risky factor when new antibiotics are developed is ensuring they do not actually destroy the body's useful bacteria. If this happens in a patient, he or she is then diagnosed as having what is medically described as a secondary infection. But the most troublesome quandary of the antibiotic research and development scientist is that bacteria continually adapt, evolve and build resistance. Therefore the production of new, more effective antibiotics is an ongoing struggle.
B. Below is a data table containing information about common antibiotics used to treat infections. You are to investigate what types of disease these drugs are used against and list any side effects. Use this link http://en.wikipedia.org/wiki/List_of_antibiotics
Antibiotic | Brand Name | Used Against | Side Effects |
Amoxicillin | Amoxil, Polymox, Wymox, Trimox | ||
Ampicillin | Unasyn | ||
Ceftriaxone | Rocephin | Infections of the skin and urinary tract. | Gastrointestinal upset and diarrhea, Nausea, Allergic reactions |
Tetracycline | |||
Erythromycin | Akne-mycin, Eryderm, Ergyl, Erythrocin, staticin | ||
Monocycline | Minocin | Acne, amoebic dysentery, anthrax, cholera, respiratory infections | Gastrointestinal upset, Sensitivity to sunlight, Potential toxicity to mother and fetus during pregnancy, Enamel hypoplasia staining of teeth |
Penicillin | Various names |
C. Use the link below to learn about good bacteria. Pick 3 and explain why they are considered good. http://www.livestrong.com/article/26093-list-good-bacteria/
