The MMLV reverse transcriptase became a popular alternative due to its monomeric structure, which allowed for simpler cloning and modifications to the recombinant enzyme. The enzyme possesses strong RNase H activity that degrades RNA in RNA:cDNA hybrids, resulting in shorter cDNA fragments (<5 kb). The AMV reverse transcriptase was one of the first enzymes isolated for cDNA synthesis in the lab. Most reverse transcriptases used in molecular biology are derived from the pol gene of avian myeloblastosis virus (AMV) or Moloney murine leukemia virus (MMLV). Once purified, RNA should be stored at –80☌ with minimal freeze-thaw cycles. Optimal purification methods remove endogenous compounds, like complex polysaccharides and humic acid from plant tissues that interfere with enzyme activity and common inhibitors of reverse transcriptases, such as salts, metal ions, ethanol, and phenol. The main goals of isolation workflows are to stabilize RNA molecules, to inhibit RNases, and to maximize yield with proper storage and extraction methods. To isolate and purify RNA, a variety of strategies are available depending on the type of source materials (e.g., blood, tissues, cells, plants) and goals of the experiments. Best practices to prevent degradation of RNA include wearing gloves, pipetting with aerosol-barrier tips, using nuclease-free labware and reagents, and decontamination of work areas. Maintaining RNA integrity is critical and requires special precautions during extraction, processing, storage, and experimental use.
Total RNA is routinely used in cDNA synthesis for downstream applications such as RT-(q)PCR, whereas specific types of RNAs (e.g., messenger RNA (mRNA) and small RNAs such as miRNA) may be enriched for certain applications like cDNA library construction and miRNA profiling. Step 2: Use your mouse to select the text that would like to format as superscript.RNA serves as the template in cDNA synthesis. You can remove superscript formatting in the same manner that you will be adding it in the steps below. The formatted text will appear smaller and vertically aligned at the top of the line on which it is located.

The steps below will show you how to select a bit of text in Word 2013 and format it it to be superscript. Formatting Text as Superscript in Word 2013 Our guide below will walk you through the steps of selecting text in your document and applying the superscript formatting to that text. Word 2013 uses a formatting option called Superscript to achieve this look. These numbers typically represent squared or cubed numerical operations. One commonly applied formatting type for numbers involves the use of small numbers that float above the baseline on a row of you document. Whether you are writing a report for an English class, or solving a math problem, there is a lot of potential formatting that you might need to use.
Word 2013 can contain many different types of information that requires many different types of formatting.
