educating the presenter and crew about aspects of DNA structure. Task 1 Produce an information sheet about the structures of the nucleic acids – this will be given to members of the production crew. (must include the following nucleic acids DNA‚ RNA‚ mRNA‚ tRNA). (P1) Task 2 Produce a poster for the presenter which clearly explains the relationship between the sequence of bases in DNA and the sequence of amino acids in a protein. (M1) Task 3 Produce a flow diagram or PowerPoint presentation

A. Genetics Ribosomal 5S RNA can be represented as a sequence of 120 nucleotides. Each nucleotide can be represented by one of four characters: A (adenine)‚ G (guanine)‚ C (cytosine)‚ o U (uracil). The characters occur with different probabilities for each person. We wish to test if a new sequence is the same as ribosomal 5S RNA. For this purpose‚ we replicate the new sequence 100 times and find that there are 60 A’s in the 20th position. Use a 0.5 level of significance. 1. If the probability of

The Prophet Muhammad: a mercy for all creation “Indeed‚ in this [Quran] is notification for a worshipping people. And We have not sent you‚ [O Muhammad]‚ except as a mercy to the worlds.” (Quran: 21:106-107) Allah’s Messenger was the kindest of men in the same way as he excelled all others in courage and valour. Being extremely kind-hearted‚ his eyes brimmed with tears at the slightest sign of inhumanity. A Companion‚ Shaddaad bin ’Aws reported the Apostle as saying: "Allah has commanded you to

information is made to be stored in DNA. Upon starting transcription‚ proteins are made to read the DNA called rRNA. A second process is involved called splicing. This is where unnecessary parts of RNA are made to create the gene the protein has sent out to make. After all necessary changes have been made to RNA‚ mRNA is decoded by the ribosome to produce a specific amino acid chains‚ or polypeptide‚ that will later fold into an active protein. This sets up the last set of what it takes to make the necessary

such as Trithorax-reponse elements (TREs) with produces Non-coding RNA that helps stimulate the appearance of the Ubx gene by inviting the protein Ash1 to the TREs. The transgenic transcription of non-coding TRE RNA can change the type and function of cells within the body. Next‚ the article concludes that researchers are now focusing on how noncoding RNAs silence genes. The UCR researchers work‚ so far‚ have revealed that noncoding RNAs have an extensive range of functions than was previously known

DNA synthesis inhibitors Nucleic acid inhibitors are chemicals which inhibit the production of nucleic acids including both DNA and RNA. DNA and RNA inhibitors inhibit enzyme action in DNA replication in the same way as the topoisomerase inhibitors we discussed earlier. Topoisomerase inhibitors (1) (10) are chemicals which interfere with the enzymes that allow DNA strands to separate and to re-join‚ a process that is required for the division of bacteria and without which DNA cannot effectively

Pg. 287 #1‚3‚4 1. Describe the structure of a nucleotide. A nucleotide is a sugar molecule that has 3 parts including a simple sugar‚ a phosphate group and a nitrogenous base. Nucleotides join together forming long chains‚ with the phosphate group of nucleotide bonding to the deoxyribose sugar of an adjacent nucleotide. 3. Explain why the structure of a DNA molecule is often described as a zipper. The structure of a DNA molecule is often described as a zipper because it is made of tow chains

Amino Acids Amino acids are biologically organic compounds containing amine and carboxylic acid functional groups‚ usually along with a side-chain specific to each amino acid. The elements that are key of an amino acid are carbon‚ hydrogen‚ oxygen‚ and nitrogen. There are about 500 different kinds of amino acids found but we recognize 23 of the amino acids that are known‚ they are classified into three groups‚ essential semi-essential‚ and non-essential. Each amino acid has unique characteristics

“Every aspet of an organism is determined or influenced by the genes of the organism” What genes are‚ what they do‚ how they interact with eachother and the enviroment to generate a phenotype. Genes are segments of DNA that code for proteins or RNA molecules. These genes are the genetic material that is passed down from generation to generation in all species. The individual DNA segments each individual carries are known as their alleles or genotype. When two alleles are identical they are homozygous
