Summary
Alternative transcripts explain the protein diversity in organisms. Rapid Amplification of cDNA Ends (RACE) is a cost-effective method to identify these alternative gene transcripts when only partial sequences are known.
Area of Science:
- Molecular Biology
- Genomics
Background:
- Organisms possess more proteins than directly encoded by genes, a phenomenon partly explained by alternative splicing.
- Different isoforms arising from the same gene can exhibit distinct biological functions, necessitating comprehensive transcript identification.
Purpose of the Study:
- To detail the methodology for identifying alternative gene transcripts.
- To present Rapid Amplification of cDNA Ends (RACE) as a tool for transcript discovery.
Main Methods:
- The study outlines the "New Race" technique for amplifying complementary DNA (cDNA) ends.
- This method facilitates the identification of 5' and 3' cDNA ends of alternative transcripts.
Main Results:
- Rapid Amplification of cDNA Ends (RACE) is presented as an inexpensive and effective approach.
- The technique enables the rapid identification of alternative transcripts from known partial or complete sequences.
Conclusions:
- Understanding alternative transcripts is crucial due to their diverse functional roles.
- RACE offers a practical solution for exploring the full spectrum of gene expression products.

02:35RACE - Rapid Amplification of cDNA Ends
Rapid Amplification of cDNA Ends, or RACE, is one of the most effective methods to obtain a full-length cDNA from an mRNA sequence between a known internal region to the unknown sequence at the 5’ or 3’ end. The unknown region is cloned in the cDNA by a gene-specific primer that binds the known end, and a hybrid primer that attaches a predefined anchor sequence to the unknown end of the cDNA. The sequence in between is amplified by PCR with an anchor primer and a gene-specific primer.

RNA sequencing, or RNA-Seq, is a high-throughput sequencing technology used to study the transcriptome of a cell. Transcriptomics helps to interpret the functional elements of a genome and identify the molecular constituents of an organism. Additionally, it also helps in understanding the development of an organism and the occurrence of diseases.

Real-time reverse transcription-polymerase chain reaction, or Real-time RT-PCR, is an analytical tool used to determine the expression level of target genes. The method involves converting mRNA to complementary DNA with the help of an enzyme known as reverse transcriptase, followed by the PCR amplification of the cDNA. These two processes can be performed simultaneously in a single tube or separately as a two-step reaction.
