3. enzymes synthesizes short RNA sequences.

It seems like your statement is incomplete or lacks a specific question. However, I can provide some information about enzymes that synthesize short RNA sequences. Enzymes known as RNA polymerases are responsible for synthesizing RNA from a DNA template. In the context of synthesizing short RNA sequences, there are specific types of RNA polymerases that can be used, such as: 1. **T7 RNA Polymerase**: This enzyme is often used in laboratory settings to synthesize RNA from a DNA template containing a T7 promoter. 2. **SP6 and T3 RNA Polymerases**: Similar to T7, these enzymes are used for synthesizing RNA from DNA templates with their respective promoters. 3. **Reverse Transcriptase**: This enzyme synthesizes complementary RNA from an RNA template, which can be useful in creating short RNA sequences from existing RNA. If you have a specific question or need further details about a particular aspect of RNA synthesis or enzymes, please provide more context!
