Non-financial rewards: * appreciation of hard work * a sense of achievement * responsibility and empowerment * opportunity for advancement * a sense of challenge and enjoyment. 2. Describe the effects of an unmotivated workforce on a company. How

DNA molecules are very long. They wrap around proteins and wind tightly‚ forming structures called chromosomes. A human somatic (non-sex) cell has 23 pairs of chromosomes. Twenty-two pairs are autosomes‚ which do not differ between the sexes. The autosomes are numbered from 1 to 22‚ with 1 the largest. The other two chromosomes‚ the X and the Y‚ are sex chromosomes. The Y chromosome bears genes that determine maleness. In humans‚ a female has two X chromosomes and a male has one X and one Y. Charts

Describe the key structures and functions of a eukaryotic and prokaryotic cell. Eukaryotic Cell (1) There are many organelles in the eukaryotic cell micrograph above. Some of these organelles are displayed in the prokaryotic micrograph and so‚ I have described the shared organelles in the prokaryotic micrograph section. Mitochondria The mitochondria cells break down nutrients which then creates energy. They act like a digestive system. This process is called cellular respiration. The

DNA replication is a biological process that occurs in all living organisms and copies their DNA. DNA replication during mitosis is the basis for biological inheritance. The process of DNA replication starts when one double-stranded DNA molecule produces two identical copies of the molecule. Each strand of the original double-stranded DNA molecule serves as template for the production of the complementary strand‚ a process referred to as semiconservative replication. Cellular proofreading and error-checking

DNA Assignment Keshia Yeates BIOLOGY 4U 1. DNA molecule with a length of 2m can fit inside a nucleus that is invisible by the naked eye by coiling around itself several times. It continues to coil even more (Supercoiling)‚ arranging itself on histones‚ which are proteins. 2. Nitrogen bases determine the traits of living organisms by coding the 20 amino acids. The order of the amino acids determines what protein is made; therefore‚ proteins are the makeup of all living organisms. Proteins regulate

DNA and the Gene: Synthesis and Repair 1) Watson and Crick elucidated the structure of DNA in 1953. Their research built on and helped explain the findings of other scientists‚ including ________. A) X-ray diffraction studies by Rosalind Franklin and Maurice Wilkins. B) Chargaff’s rules: C = G and T = A. C) Scientists who recognized that a nucleotide consisted of a sugar‚ a phosphate‚ and a nitrogen-containing base. D) All of the above were important considerations in the elucidation of
