Ozolins Physical Anthropology 101 September 10‚ 2014 Homework # 1 DNA 2. Name the four differences between RNA and DNA. 1) DNA is double stranded‚ RNA is single 2) DNA has Adenine‚ Guanine‚ Thiame‚ and Cytosine as nitro bases. With RNA‚ anywhere you would expect to see Thaime‚ you see Uracil instead. 3) DNA has no types‚ RNA has 3 types: mRNA‚ rRNA‚ and tRNA. 4) DNA and RNA have different sugars. 3. For the following DNS strand‚ provide the replicated strand : GATTACACATTAG

Ribonucleic acid is popularly known as RNA. RNA is one of the three major macromolecules (along with DNA and proteins) that are essential for all known forms of life. RNA stands for ribonucleic acid. It is an important molecule with long chains of nucleotides. A nucleotide contains a nitrogenous base‚ a ribose sugar‚ and a phosphate. Just like DNA‚ RNA is vital for living beings. The main job of RNA is to transfer the genetic code need for the creation of proteins from the nucleus to the ribosome

Making Bread with Yeast By Rebecca Coles Introduction Bread is such a common food‚ who would expect it to be made in such a fascinating and clever way? A simple loaf contains just four main ingredients; flour (the main ingredient)‚ warm water (the yeast prefer the water warm)‚ salt and of course the yeast‚ tiny microscopic fungi that help the bread rise. Although fascinating the process is surprisingly simple; first‚ the flour‚ sugar and water is mixed together with yeast to make the bread

October 12th 2014! The Effect of Glucose on The Cellular Respiration of Yeast! Purpose: ! The purpose of this lab is to determine if the quantity glucose solution will increase or decrease the rate at which cellular respiration occurs at within the tested 20% yeast suspension.! Question:! What are the effects of increasing or decreasing the quantity of 0.06mol/L glucose solution on the cellular respiration within the tested yeast molecules?! Hypothesis: ! When the quantity of glucose solution is increased

Hensen’s Node used as the RNA source? Hensen’s node is the neural organizer in amniotes which signals the primitive streak‚ the site of invagination during blastulation. Grafting of Hensen’s node to the anterolateral region generates a patterned nervous system (Stern‚ 2005). RNA from Hensen’s node was used because Hensen’s node is the site of neural induction and as such‚ proteins encoded by expressed transcripts in this region should be implicated in induction and gastrulation. RNA was used to generate

There are more than one forms of fermentation; yeast fermentation is probably the most common method. This process is used in many everyday products today. Yeast was first discovered in 1676‚ but was used before. It has also led to numerous scientific advances. Yeast expands‚ especially well with a good amount of sugar‚ the more of the amount the greater it expands. Yeast is a single-celled organism‚ a fungus to be more specific. They consume carbohydrates‚ mainly sugars‚ and produce carbon dioxide

DNA – RNA Notes The sugar in DNA is called deoxyribose. The sugar in RNA is called ribose. -RNA is a single strand of nucleotides. DNA is made of two strands of nucleotides. -DNA is a double helix with hydrogen bonds linking the nitrogen bases. RNA is a linear strand with no hydrogen bonds. -The bases of DNA are: Adenine‚ Thymine‚ Cytosine‚ and Guanine. The bases of RNA are: Adenine‚ Uracil‚ Cytosine‚ and Guanine. -RNA does not have Thymine‚ and DNA does not have Uracil. -In DNA

Cervisiae<br><br><b>Description</b> - Yeast is a unicellular organism that lacks chloroplasts. They are so small that it can ’t be seen by the naked eye and they are so small that it would take 4000 of them lined up side by side to measure an inch. <br><br><b>Habitat</b> - Yeast lives on and is nourished by dead or living plant or animal matter. The ideal conditions of yeast is high humidity and temperature‚ plus lots of food. In bad conditions though the yeast produces a second cell wall for protection and the yeast contents
