t - RNA is also known as

Options

A. Adapter molecule
B. Messenger RNA
C. Soluble RNA
D. Both (A) and (C)

Answer

To determine what tRNA is also known as, we can analyze the options provided:

1. **Adapted Molecule**:
- tRNA is often referred to as an "adapter" molecule because it plays a crucial role in translating the genetic code from mRNA into a sequence of amino acids during protein synthesis. It carries specific amino acids to the ribosome, where the mRNA is read. Therefore, this option is correct.

2. **Messenger RNA (mRNA)**:
- This option is incorrect. mRNA is a different type of RNA that carries the genetic information from DNA to the ribosome for protein synthesis. It is not synonymous with tRNA.

3. **Soluble RNA**:
- tRNA is also known as soluble RNA because it is soluble in salt solutions, such as 1 mole of NaCl. This characteristic is often used to describe tRNA, making this option correct as well.

4. **Combination of Options**:
- Since both "Adapted Molecule" and "Soluble RNA" are correct, the best answer would be an option that includes both of these terms.

**Final Answer**: tRNA is also known as an "Adapter Molecule" and "Soluble RNA".
