DNA Replication before Meiosis Before meiosis occurs, all of the DNA inside the nucleus of the 'parent' cell is?replicated This occurs during a period of the cell cycle known as?interphase Once thi...
Meiosis There are two processes by which the?nucleus?of a?eukaryotic cell?can?divide. These are: Mitosis Meiosis Mitosis?gives rise to?genetically identical cells?and is the type of cell division u...
Use of Databases to Identify Gene Loci Use of databases to identify the locus of a human gene and its polypeptide product Following the?sequencing of the whole human genome, we now know the?exact l...
Karyograms During the stages of mitosis,?chromosomes condense?(become visible) This is most notable in?metaphase Staining?can reveal distinctive banding patterns on chromosomes at this stage The?po...
Sex Determination Sex is determined by an?entire chromosome pair?(as opposed to most other characteristics that are just determined by one or a number of genes) Females?have the sex chromosomes (pa...
Haploid Haploid nuclei have one chromosome of each pair Haploid cells contain?one complete set of chromosomes (n) In other words, they have?half?the number of chromosomes compared to normal body ce...
Eukaryotic Chromosomes Chromosomes in eukaryotic cells are?one,?very long?DNA molecule associated with proteins The main proteins present are the large, positively charged globular proteins called?...
Prokaryotic Chromosomes The DNA in prokaryotic cells is significantly different from the DNA found in eukaryotic cells Prokaryotes?do not contain a nucleus?therefore the DNA is located in the cytop...
Genome The?total of all the genetic information in an organism?is called the?genome?of the organism This is a?complete set of genes?present within every cell of an organism This includes?all genes?...
