Meiosis vs Mitosis - Medical Animation
MEDICAL ANIMATION TRANSCRIPT: Mitosis is a type of cell division with many vital functions including embryonic development, promoting tissue growth after birth, and replacing damaged or dying cells in the body. In mitosis, there is one division, and the resulting two daughter cells contain the same number of chromosomes as the parental cell. These cells are called diploid cells because they contain 23 pairs of chromosomes with each pair containing one maternal and one paternal chromosome. After DNA replication, mitosis begins with prophase, during which chromatin condenses into chromosomes, each consisting of two identical sister chromatids. The nuclear envelope dissolves, and spindle fibers begin to grow from the cell's centrioles. During metaphase, the spindle fibers pull the chromosomes into alignment in the center of the cell. In anaphase, each chromosome consisting of two genetically identical chromatids splits in two. Each chromatid, now considered a single-stranded daughter chromosome, migrates to the opposite end of the cell from its twin. During telophase, nuclear envelopes reform around the chromosomes as the cell finishes dividing. Meiosis is a type of cell division with one purpose, to produce eggs and sperm called gametes. In meiosis, there are two divisions in succession, resulting in four daughter cells. Each daughter cell contains half the number of chromosomes of the initial parental cell. The daughter cells are called haploid cells because they contain 23 unpaired chromosomes. After DNA replication, the first cell division, or meiosis 1, begins with prophase 1, during which chromosomes condense. Late in prophase 1, chromatids in each pair break and exchange corresponding sections of DNA in a process called crossing over, thus creating new combinations of genes. During metaphase 1, homologous chromosome pairs line up in the center of the cell. Each pair can line up randomly from left to right in a process called independent assortment. In anaphase 1, each pair of chromosomes separates, and in telophase 1, the cell divides, resulting in two haploid daughter cells. The second meiotic division, or meiosis 2, begins with prophase 2, during which the cell prepares to divide again. In metaphase 2, the chromosomes line up in the center of the cell. During anaphase 2, each chromosome is pulled apart into two sister chromatids, each now considered a single-stranded chromosome. In telophase 2, the two cells divide, resulting in four haploid daughter cells. Once meiosis is complete, the male and female gametes each contain a unique set of 23 single-stranded chromosomes, ultimately resulting in the genetic variability of humans. Once these gametes meet, they become a single fertilized cell called a zygote. The zygote has 46 chromosomes, and continues to develop using mitosis. ♪ [music] ♪

What attorneys say about MLA and The Doe Report:
"We got a defense verdict yesterday! Your exhibit was extremely helpful in showing the jury how unlikely it is to damage all four of the nerve branches which control the sense of taste."

"It is with great enthusiasm that I recommend Medical Legal Art. We have used their services for three years and always found their professionalism, quality of work, and timely attention to detail to exceed our expectations. We recently settled two complicated catastrophic injury cases. One medical malpractice case involving a spinal abscess settled for 3.75 million and the other involving injuries related to a motor vehicle accident settled for 6.9 million. We consider the artwork provided by MLA to have been invaluable in helping us to successfully conclude these cases.

I highly recommend MLA to anyone seeking high quality, detailed medical legal artwork."

"It is my experience that it's much more effective to show a jury what happened than simply to tell a jury what happened. In this day and age where people are used to getting information visually, through television and other visual media, I would be at a disadvantage using only words.

I teach a Litigation Process class at the University of Baltimore Law Schooland use [Medical Legal Art's] animation in my class. Students always saythat they never really understood what happened to [to my client] until theysaw the animation.

Animations are powerful communication tools that should be used wheneverpossible to persuade juries."

"Your firm is great to work with and, most importantly for me, you get the job done on time and with the utmost professionalism. You should be proud of all those you employ, from KJ to Ben B. I've been especially pleased over the years with the work of Brian and Alice, both of whom seem to tolerate my idiosycratic compulsion to edit, but I've not found a bad apple in the bunch (and, as you know, I've used your firm a bunch!). I look forward to our continued professional relationship."
