Following Chromosomal Dna Movement Procedure Meiosis I

REPLICATION WITHIN MITOSIS AND MEIOSIS ABSTRACT The processes of mitosis and meiosis were examined along with their frequency as well as each of the different steps and their time duration. It was found that the interphase stage of both mitosis and meiosis was the longest of all the stages as this was where most of the ‘action’ was happening such as cell growth and duplication of all cell organelles and chromosome replication also. It was also found that mitosis and meiosis have similar stages, however...

Lab 6: Isolation of Chromosomal Dna

Lab 6: Isolation of Chromosomal DNA Mic 428L/ Section 001 Introduction: In biological research to address and eventually answer a multitude of questions, usually involves isolating chromosomal DNA. The purpose in this particular lab was to isolate chromosomal DNA from mutants grown and observed in lab 5 and then digest the DNA using a restriction enzyme. The fragments left from digestion will be ligated and then transformed into a strain of E. Coli DH5αλpir containing the pir gene pi product...

Questions and Answers on DNA and Chromosomes

forms of proteins contained in DNA. When gametes are formed, the male and female parents pass along their DNA into their respective gametes. Fertilization fuses the gametes and combines the genetic contribution of each parent into the new offspring. 2. Distinguish between asexual and sexual reproduction. Asexual Reproduction-A form of reproduction which does not involve meiosis or fertilization without fusion of gametes. Sexual Reproduction- Has two processes: meiosis, involving halving the number...

Stages of Meiosis

Meiosis I Prophase I: - nuclear membrane dissolves * centrioles move to poles * spindle fibres forming * DNA has been replicated and forms chromosomes made of 2 identical chromatids * Homologous chromosomes line up to form a bivalent, 2 chromosomes or 4 chromatids (TETRAD), this process is called SYNAPSIS * Where chromatids overlap is called a CHIASMATA, and it allows for CROSSING OVER of genetic information between chromosomes Metaphase I: - homologous chromosomes...

Chromosomal Aberrations

Balao, Mike Paul C. MT1311 Chromosomal aberrations are abnormalities in the structure or number of chromosomes and are often responsible for genetic disorders. For more than a century, scientists have been fascinated by the study of human chromosomes. It was not until 1956, however, that it was determined that the actual diploid number of chromosomes in a human cell was forty-six (22 pairs of autosomes and two sex chromosomes make up the human genome). In 1959 two discoveries opened a new era...
