DNA Replication Deoxyribonucleic acid (DNA) contains the genetic instructions for the biological development of a cellular form of life including some viruses. DNA is an antiparallel double helix molecule with sugar-phosphate backbone on the outer side and nitrogen bases in the inner side. The bases are paired specifically‚ also known as complementary pairing‚ Adenine (A) with Thymine (T)‚ and Guanine (G) with Cytosine (C) by two and three hydrogen bonds‚ respectively. DNA is a long polymer

coat that protects these genes; and some have an envelope of fat that surrounds them when they are outside a cell What is a fungus? These are Eukaryotes when compared to bacteria(prokaryote) and virus. Like plants and animals‚ fungi are eukaryotic multicellular organisms. One major difference is that fungal cells have cell walls that contain chitin‚ unlike the cell walls of plants‚ which contain cellulose. The chitin adds rigidity and structural support to the thin cells of the fungus‚ and makes

reproduction and for the growth and repair of multicellular organisms‚ including humans. Two Major Kinds of Cells Eukaryotic cells- Membrane enclosed organelles in which DNA is organized along with certain proteins into structures called chromosomes contained within a nucleus‚ the largest organelle of most eukaryotic cells. Around the nucleus is a cytoplasm in which are suspended the various organelles that perform most of the cells functions. Plants eukaryotic cells have tough cell walls external to

Introduction to sexual reproduction in humans Reproduction is the process by which humans gives rise to new individuals. Sexual reproduction is the process that involves the fusion of two gametes‚ sperm (male gamete) and egg (female gamete). In human these gametes are produced in different sexes‚ the male and female. Reproduction in humans is performed by reproductive systems‚ the male and female reproductive systems. The main organs of male reproductive system are testis and gonads and of female
