Presentation Transcript

Slide 1

Cell Reproduction and Inheritance Duplicating Genetic Information The Cell Cycle Cancer and the Cell Cycle Mitosis Meiosis When Cell Division is not impeccable

Slide 2

Duplicating Genetic Information about you is in the succession of nucleotides in the DNA particle In each of your cells, there is around 2 meters of DNA per core How does the DNA gather into, for example, little zone? DNA histones chromatin

Slide 3

Duplicating Genetic Information Chromatin can consolidate into a chromosome Telomere Centromere Telomere

Slide 5

Duplicating Genetic Information Humans have 46 Chromosomes are described by length Position of the centromere Banding design

Slide 6

Duplicating Genetic Information So people have 46 chromosomes with 23 sets . You can see recolored chromosomes and these can be masterminded in sets. The photo of masterminded chromosomes is known as a karyotype .

Slide 11

Humans Have 46 Chromosomes 23 sets 2n = 46 2 is the quantity of duplicates of every chromosome n = the quantity of various chromosomes 46 is the aggregate number of chromosomes in the cell

Slide 12

Let's Try Some! 2n = 8 3n = 15 4n = 8

Slide 13

The Cell Cycle Phases include: Interphase – Preparation stages for Mitosis – Cell division or part Interphase G 1 (Growth) S G 2 (Growth) The Cell Cycle

Slide 14

The Cell Cycle

Slide 15

Cancer and the Cell Cycle

Slide 16

Cancer and the Cell Cycle A disease cell has unregulated cell development Often, the cell cycle checkpoints don't exist. What is growth? Could you get disease? What are the medicines for malignancy? What would it be advisable for me to search for? http://www.cancer.org/1-800 – 4 CANCER

Slide 17

Why Mitosis Growth and Repair Products are indistinguishable duplicates

Slide 29

Meiosis – a procedure that lessens the chromosome number in a manner that the girl cores just get one individual from each homologous match of chromosomes. Consider it a twofold mitotic division with just a solitary S stage Phases of meiosis Prophase I 6. Prophase II Metaphase I 7. Metaphase II Anaphase I 8. Anaphase II Telophase I 9. Telophase II Interkinesis

Slide 42

Prophase I Crossing over of non-sister chromatids During prophase I, non-sister chromatids can experience synapsis , in which the chromatids line up one next to the other & trade hereditary data between them This permits new mix of hereditary material which will turn out to be a piece of another posterity

Slide 47

Prophase I & Metaphase I Independent arrangement As the chromosomes are pushed around amid prophase I, inevitably arranging along the metaphase plate amid metaphase I, their introduction is unique in relation to that of mitosis metaphase Instead of covering one on top of the other, the imitated chromosomes line up one next to the other as per their homologous characterstics

Slide 50

Meiosis I Mitosis Prophase I Prophase Pairing of chromosomes No blending Metaphase I Metaphase Homologous chromosomes at Duplicated chromosomes at Metaphase plate metaphase plate Anaphase I Anaphase Homologous chromosomes separate Sister chromatids particular, getting to be Daughter chromosomes Telophase I Telophase Daughter cells are haploid Daughter cells are diploid

Slide 51

Meiosis II Mitosis Prophase II Prophase No matching of chromosomes No matching Metaphase II Metaphase Haploid # of chromosomes at metaphase Diploid # of copied chromosomes at plate metaphase plate Anaphase II Anaphase Sister chromatids discrete, getting to be Sister chromatids isolated, getting to be little girl chromosomes daughter chromosomes Telophase I Telophase 4 haploid girl cells Daughter cells are diploid
