This lecture explains about the genetic drift and the example of genetic drift events such as the bottleneck effect and the founder effect that explains the change in the genetic frequency with time by random chance. Genetic drift describes random fluctuations in the numbers of gene variants in a population. Genetic drift takes place when the occurrence of variant forms of a gene, called alleles, increases and decreases by chance over time. These variations in the presence of alleles are measured as changes in allele frequencies.

На занятии:
— сможешь ответить на вопрос о сущности рынка;
— научишься различать рынок монополистической конкуренции от олигополии;
— будешь видеть экономические явления в бабках с укропом;
— начнёшь щёлкать задания о конкуренции как орешки!

Гистология цитоплазма.

Dan Schneider came face to face with unspeakable tragedy on April 14, 1999 when his 22 year old son was shot and killed while attempting to buy drugs in New Orleans. Dan speaks on his experience searching for his son’s killer, how it fueled his fight against the opioid epidemic, and how he found the light through the Tunnel of Hope.
«Im Dan Schneider. Im 70 years old and believe sharing my hard found wisdom will benefit others. I had great parents, great family 2 Older Brother and a younger sister We lived in an area that was called Gods Country. I was an all district Tackle on my high School football team.
I married my high school sweetheart, Annie, in 1971. She worked, I went to Pharmacy School and worked part-time. I became a Pharmacist in 1975 and she became a stay at home Mom. Our son Danny was born 9/27/76. Lil Danny was a blond haired blue eyed beautiful boy. He brought us much joy. Our daughter Kristi came along in 1980 and completed what many called the Griswald family. Station wagon, family trips, and a 17 ft. Christmas tree.
On 4/14/1999 our life changed. Our son was murdered while trying to buy drugs.

Our story was told in in the Netflix docuseries „“The Pharmacist»" .The story is not over, it is still being written. We are trying to build a nationwide movement to end the Opioid and Addiction Pandemic that has killed nearly a million since since my son died. I call our Mission "«The Tunnel of Hope»", as we hope to bring light to this dark National Tragedy." Im 70 years old and believe sharing my hard found wisdom will benefit others.

До сих пор много тайн клетки остаются неразгаданными. Загадочным во многом остаётся и запрограммированный генетически алгоритм её жизни, названный жизненным циклом клетки. Одним из этапов жизненного цикла является митоз, о нём и пойдёт речь в этом уроке.
