Mendel’s principles of inheritance in that it shows how chromosome pairs from prophase of meiosis-1 split and migrate to opposite poles and then into separate gametes. Also‚ this splitting of chromosomes occurred apart from the splitting of the other chromosomes in that cell. 4. Recombination involves the rearrangement of genes by random chromosome assortment and crossing over with occurs during meiosis. Mutations‚ however‚ are unprecedented changes in genes which gives rise to entirely new forms

chromosomes. Males have one X and one Y‚ while females have 2 X and no Y-chromosomes. During meiosis‚ the number of chromosomes is reduced and genetic information is shuffled allowing for variations‚ such as eye or hair color. Occasionally however‚ humans are born with an abnormal number of chromosomes because they incorrectly separate during meiosis. This is called nondisjunction‚ and can happen during meiosis I when both members of the same homologous pair go into the same daughter cell or II‚ if the

blocks which is known as flagella. It has no cytoskeleton.It’s cell division is called binary fission. It’s DNA structure is a single circular chromosome.It has smaller ribosomes. It’s cell size is between 1-10um. Sexual reproduction involves no meiosis and transfer of DNA fragments (Prokaryote vs. Eukaryote‚ September 2014).

In prokaryotes‚ it’s easier to make DNA replication because of the lack of a nucleus‚ but to do DNA replication in a eukaryotic cell is more difficult. DNA of an eukaryotic cell is in chromatin form to fit into the small nucleus for the replication to occur‚ first the DNA should open. This is because it is harder for eukaryotes to carry out DNA synthesis. Replication of DNA in a prokaryote is different from a eukaryote. In a prokaryote they have a single origin where the replication process starts
