Synthesis of enzymes takes place by

In which process does the transfer of genetic information occur?

Define/Explain the following:
$1.$ Transfer $\text{RNA}$ $(t\text{-RNA})$
$2.$ Ribosomal $\text{RNA}$ $(r\text{-RNA})$

The function of $tRNA$ is

In a $t-RNA$ molecule,the sequence of three consecutive bases that specifically binds to a complementary codon sequence on $m-RNA$ is known as:

How many nucleotides does a $t-RNA$ molecule typically contain?
