Get Nutrigenomics (Oxidative Stress and Disease) PDF

Dietary genomics, also called nutrigenomics, is taken into account one of many subsequent frontiers within the post-genomic period. Its primary premise is that whereas adjustments in gene expression or epigenetic phenomena can subvert a fit phenotype into manifesting continual affliction, throughout the advent of definite nutrition, this procedure could be reversed or changed.

Sample text

Each chromatid consists of a single, tightly coiled molecule of DNA. Somatic cells (all body cells except eggs and sperm) are diploid cells because each cell contains two copies of every chromosome. A pair of such chromosomes is called a homologous pair. In a homologous pair of chromosomes, one homologue originates from the maternal parent, the other from the paternal parent. There are 46 chromosomes, 23 homologous pairs, consisting of a total of 92 chromatids. When a cell is not dividing, the chromatin is enclosed within a clearly defined nuclear envelope, one or more nucleoli are visible within the nucleus, and two centrosomes (each containing two centrioles) lie adjacent to one another outside the nuclear envelope.

DNA polymerase initiates replication by itself via the utilization of DNA nucleotides. During ______, DNA is unzipped into two separate strands by RNA polymerase. Critical Thinking Questions 1. Why is genetic recombination so crucial for a species? 2. Take the following single strand of DNA (5’ G-C-T-A-C-T 3’) throughout the three steps of protein synthesis. What two amino acids would result? Answers: 1. Microtubules 2. T 3. b 4. F 5. transcription Chapter 3 TISSUES Chapter Check-In ❑ Discovering the four basic types of tissue ❑ Listing the general characteristics and functions of the different types of epithelium ❑ Describing the various kinds of connective tissue and their components ❑ Understanding the different kinds of nervous tissue and muscle pproximately 200 distinctly different types of cells compose the human body.

Overlapping microtubules originating from opposite centrosomes but not attached to chromosomes interact to push the poles farther apart. At the end of anaphase, each pole has a complete set of chromosomes, the same number of chromosomes as the original cell. ) ■ Telophase concludes the nuclear division. During this phase, a nuclear envelope develops around each pole, forming two nuclei. The chromosomes within each of these nuclei disperse into chromatin, and the nuclei reappear. Simultaneously, cytokinesis occurs, dividing the 30 CliffsQuickReview Anatomy and Physiology cytoplasm into two cells.
