Key Concepts ? Inherited traits are affected by genes. ? Genes are composed of the chemical deoxyribonucleic acid (DNA). ? DNA replicates to form (usually identical) copies of itself. ? DNA contains a code specifying what types of enzymes and other proteins are made in cells. ? DNA occasionally mutates, and the mutant forms specify altered proteins. ? A mutant enzyme is an ?inborn error of metabolism? that blocks one step in a bio- chemical pathway for the metabolism of small molecules. ? Traits are affected by environment as well as by genes. ? Organisms change genetically through generations in the process of biological evolution. ? Because of their common descent, organisms share many features of their genetics and biochemistry.

14.1 Structure of ribonucleic acid The genetic code Sequence of nucleotides in DNA forms a code that determines the sequence of amino acids in the proteins. In eukaryotes the DNA code is largely confined to the nucleus. The synthesis of proteins takes place in the cytoplasm. Sections of the DNA code are transcribed onto a single-stranded molecule called ribonucleic acid RNA. There are a number of types of RNA. The one that transfers the DNA code from the nucleus to the cytoplasm acts as a type of messenger and is called messenger RNA (mRNA). This mRNA is small enough to leave the nucleus through the nuclear pores and to enter the cytoplasm, where the code that it contains is used to determine the sequence of amino acids in the proteins which are synthesised there.

Semester 2: Biology Vocabulary Dominant - A comparative term, where one allele is expressed over the other True Breeding- The process of breeding of two organisms with an identical phenotype to procreate an organism with the same phenotype Recessive ? A comparative term, where one allele is not expressed over the other Sexual selection ? A process where mate is chosen based on certain characteristics or traits Homologous structures ? Structures that appear to be similar in different organisms, suggesting a common ancestry or an evolutionary origin. Selective breeding ? A process of breeding for a particular genetic trait Derived structures ? Structures that appear in the ancestor of a group or species, but do not appear in the other species.
