Answer #1

a) Synthesis of RNA primer. RNA primer is synthesised by primase enzyme which is required for DNA replication.

b) Activation of amino acids. It refers to the attachment of an amino acid to its Transfer RNA. This aminoacid linked tRNA has an anticodon binds with processed mRNA has a codon to synthesis polypeptide chain.

c) Binding of DNA and RNA together.

d) Synthesis of mRNAs. mRNA is synthesized in the nucleus using DNA as template. The process of making mRNA from DNA is called transcription.

Answer: b) Activation of amino acids. It is the first step in which the correct amino acid is covalently bonded to correct tranfer RNA. After the activation, initiation occurs. And finally polypeptide chain is formed in translation process.
