Virtual Lab: Classifying Using Biotechnology Worksheet NOTE: As you read the information in the Microbiology Handbook‚ there may be some terms you are not familiar with – such as 16s ribosomal RNA and Polymerase Chain Reaction. Refer to your text to read background material explaining any terms or processes with which you are not familiar. Record the results of your investigations of each unknown in Table 1 by completing the following steps: 1) Apply the stain to your first

Provides evidence for Unit 18 D1 Distinction. Describe the process of protein synthesis in your own words‚ including the roles of mRNA and tRNA. You MUST include diagrams to aid in your explanations Messenger ribonucleic acid (mRNA)‚ which is like DNA has a unique code that is in a number of different patterns‚ which engages in the sending messages to the structures within the cell. Transfer Ribonucleic Acid (tRNA) is a nucleic acid‚ which is involved in the process of protein synthesis inside

Lassa Fever: An Old World Arenavirus ABSTRACT A brief summary of lassa fever‚ its history‚ pathology and effects on the indigenous populations. Also‚ lassa fever in the context of newly emerging diseases. LASSA FEVER On January 12‚ 1969‚ a missionary nun‚ working in the small town of Lassa‚ Nigeria‚ began complaining of a backache. Thinking she had merely pulled a muscle‚ she ignored the pain and went on about her business. After a week‚ however‚ the nurse had a throat so sore and so filled

operon: 5’-TGTTATA-3’ There are 2 nucleotides different that are G and A. Question#3: The lux R‚ which has its own promoter and is transcribed in the opposite direction from the lux operon‚ could not be transcribed from the same strand because the RNA polymerase recognizes a promoter sequence only in the direction of 5’ to 3’‚ and the lux R gets transcribed in the opposite direction from the lux operon. Thus‚ the transcriptions of luxR and lux operon have to occur on two different strands including
Premium DNA Gene Molecular biology
Protein synthesis is broken up in two two steps: transcription and translation. Transcription starts inside the nucleus when the DNA is unzipped by helicase. Following that‚ the mRNA nucleotides match to their complementary bases using an enzyme called RNA polymerase. Once they are matched‚ the mRNA exits the nucleus and goes to a ribosome in the cytoplasm to begin translation. Translation is the synthesis of a protein using the genetic information encoded in the mRNA. Translation begins when the mRNA

Experiments involving in vitro translation of short synthetic RNAs eventually confirmed that the genetic code is indeed a triplet code. The

Major Chemical Properties for Cellular Respiration: We need oxygen at the cellular level for this to be complete. Why do you need oxygen? What is your body trying to do? Your body needs to produce energy‚ which is why you go through these metabolic processes‚ and that’s ultimately why you need oxygen. So we are trying to produce ATP as our energy source. So ultimately your energy cannot be created‚ it only changes form‚ so where does that energy come from in your body? We’re going to convert it into
