    “Eukaryotic chromosomes are generally much bigger than those of prokaryotes. In eukaryotic cells‚ replication may begin at dozens or even hundreds of places on the DNA molecule‚ proceeding in both directions until each chromosome is completely copied. Although a number of proteins check DNA for chemical damage or base pair mismatches prior to replication‚ the system is not foolproof. Damaged regions of DNA are sometimes replicated‚ resulting in changes to DNA base sequences that may alter certain

    Chromosome 11 is in group C‚ it is of medium size‚ its relative length is 4.82 Chromosome 11 is submetacentric‚ meaning that the centromere is closer to one end‚ causing one longer arm and one shorter arm. The centromeric index for chromosome 11 is 40.46. Calculations can be seen below. Centromeric index = (p / p + q) x 100 (1.95 / 4.82) x 100 = 40.46 The protein that HBB gene encodes is beta-globin. Beta-globin is a component of hemoglobin. Hemoglobin is found in red blood cells‚ and it normally

    P1: Explain how sperm and ova are formed by producing an annotated diagram of meiosis and discussing what happens in ogenesis and spermatogenesis In the male‚ meiosis precedes sex cell differentiation. A single spermatogonium enters the first meiotic division as a primary spermatocyte. This division produces two secondary spermatocytes‚ each of which divides to form two haploid spermatids. Each spermatid then differentiates (by a process called spermiogenesis) into a spermatozoon by the elaboration
