Document Summary
Focus on how evolution works at level of phenotypes, genes, and population. Somatic cells- most cells in body except sex cells. Gametes- sex cells (sperm and ovum egg) Cytoplasm- complex mix of membranes, molecules, and tiny structures called organelles. Nucleus- contains hereditary material, known as chromosomes. Paired rod-shaped structures in cell nucleus contain genes that transmit traits from generation to generation. Deoxyribonucleic acid: nucleic acid used to store genetic information that codes for the synthesis of proteins. Four bases: adenine (a), guanine (g), cytosine (c) and thymine (t) Nasa reported that meteorites found on earth, contain nucleobases (such as adenine and guanine) may have formed in outer space. Linear sequence of amino acid- building blocks of cells. Each protein has specific function determined by blueprint stored in dna. For example catalysis all biochemical reaction is done by enzymes, which contain protein (digestion); and many more. Synthesis of single strand of ribonucleic acid (mrna: messenger rna) at unwound section of.
