One of the examples of carbohydrate polymer is starch and it monomer subunits is glucose (monosaccharide) with a formula of (C6H10O5) n+ (H2O). The molecules are bonded by alpha linkages. Starch is composed of two different types of polymers in itself-amylose (15-20%) and amylopectin (80-85%). It is produce by most green plants for energy storage.

According to Kaiser(2022) horizontal gene transfer (a.k.a lateral gene transfer) includes the process by which genetic materials are transfer from one organism to another different organism not from its offspring. Bacteria are microscopic single celled organisms that resides in and out or other organisms. They may or may not (provide protection like normal flora) cause harm to their host. In as much as the reside and are dependent on the environment in which the find themselves( can be inside hu...

As understood from the introduction in the learning guide about cell communication and reproduction it becomes clear that Somatic cell nuclear transfer (SCNT) includes a scientific process that involves the use of sophisticated technology to transplant the nuclei which contain genetic material from adult cell into an egg before maturation or a fertilized egg to enable growth and difference (Lee &Prather, 2014).

According to the new Science of Metagenomics: revealing the secrets of our microbial planets (2007) metagenomics is defined as the study of the structure and function of entire nucleotide sequences isolated and analyzed from every other organism in a bulk sample. Metagenomics can mainly be used to study specific community of microorganism more especially those residing in humans. Like the normal flora found in the stomach of human beings.

 Poor coordination and balance: during physical examination a patient suffering from SCAs cannot be able to coordinate movement of his index finger from the tip of his or nose to the one of the fingers of the examiner, poor swallowing.  Unsteady gait: abnormal coordination of working position or steps which is why patients of SCA are on a wheel chair especially when it suffices in their lives.  In the long term lead to breathing failure or cardiac malfunctioning because the neurons or...

I would like to relate this week assignments to cheese making which basically involves the use of pasteurized or raw milk to make cheese. Cheese making lactic acid bacteria (LAB) cultures from which the derived their energy from lactulose (got from milk products). The lactic acid derived helps to break up or build up organic materials. This lactic acid bacterisa also refer to as typical starter are Lactococcus lactis subsp. Lactis or cremoris , Streptococcus salivarius subsp. Thermophiles, Lacto...

My current diet as a Sierra Leonean with rice being our staple food comprises of over 50% of carbohydrates , 20% proteins( mostly fish, beans, groundnuts) , 10 fats and oil( from plant source), 10% vegetables( garden eggs, green leaves) , 5% fruits( oranges, mangoes , lime) and 5% vitamins and minerals. So from the statistics measure above it clearly indicates that my daily meals contain high carbohydrates followed by protein.

Across 1. protein that acts as a catalyst in biochemical reactions 6. component of fat molecule 8. acidic group in amino acids 9. monosaccharide commonly found in fruit 11. fatty acid with hydrogens in different planes 12. monomer subunit of protein 14. major constituent of plasma membrane 17. fatty acid containing no double bonds 18. nucleic acid found only in RNA 19. bond formed between two amino acids 20. number of amino acids
