BRAINCAKEProtein Synthesis
The sequence of nucleotides determines the sequence of amino acids in proteins. The information for the amino acid sequence of the protein is in the DNA in the nucleus but protein synthesis takes place in the cytoplasm.
There are different types of RNA. mRNA is a single-stranded copy of the gene to be translated into a protein and ins made in the nucleus but leaves the nucleus through nuclear pores and is used in the cytoplasm.
mRNA carries the coded information from the nucleus to the cytoplasm. tRNA helps to assemble the amino acids in the correct order.
