html怎么实现登录验证功能    英文回答：
    In this experiment, we aimed to validate the full-length sequence of a gene cDNA. Gene cDNA sequences are important for understanding gene function and expression. To validate the full-length sequence, we employed several experimental techniques.
    Firstly, we performed reverse transcription polymerase chain reaction (RT-PCR) to amplify the cDNA sequence. RT-PCR allows us to convert the RNA template into complementary DNA (cDNA) and amplify specific regions of interest. We used gene-specific primers designed based on the known gene sequence to ensure amplification of the correct cDNA fragment.
    After amplification, we purified the PCR products and performed gel electrophoresis to visualize the cDNA fragments. Gel electrophoresis separates DNA fragments based on their size, allowing us to verify the presence of the expected cDNA fragment. We compared the size of the amplified fragment with the expected size based on the known gene sequence.
    To further validate the full-length sequence, we performed Sanger sequencing. Sanger sequencing is a widely used method for determining the nucleotide sequence of DNA fragments. We sent the purified cDNA fragment to a sequencing facility, and they performed the sequencing reaction. The resulting sequence data was then analyzed to confirm the accuracy and completeness of the cDNA sequence.
    Additionally, we compared the obtained cDNA sequence with the reference genome sequence to ensure its alignment and identify any potential variations or mutations. This step is crucial to ensure the accuracy of the cDNA sequence and its relevance to the gene of interest.

    在这个实验中，我们旨在验证基因cDNA的全长序列。基因cDNA序列对于理解基因功能和表达非常重要。为了验证全长序列，我们采用了几种实验技术。
    首先，我们进行了反转录聚合酶链式反应（RT-PCR）来扩增cDNA序列。RT-PCR允许我
们将RNA模板转化为互补DNA（cDNA）并扩增感兴趣的特定区域。我们使用基于已知基因序列设计的基因特异性引物，以确保扩增正确的cDNA片段。
    扩增后，我们纯化了PCR产物，并进行凝胶电泳以可视化cDNA片段。凝胶电泳根据DNA片段的大小进行分离，使我们能够验证预期cDNA片段的存在。我们将扩增片段的大小与基于已知基因序列的预期大小进行比较。
    为了进一步验证全长序列，我们进行了Sanger测序。Sanger测序是一种广泛应用的确定DNA片段核苷酸序列的方法。我们将纯化的cDNA片段送到测序机构进行测序反应。然后，对产生的序列数据进行分析，以确认cDNA序列的准确性和完整性。
    此外，我们将获得的cDNA序列与参考基因组序列进行比较，以确保其对齐并识别任何潜在的变异或突变。这一步骤对于确保cDNA序列的准确性及其与感兴趣基因的相关性至关重要。
