Transcription is the process in which RNA copy the sequence of DNA. First of all the DNA unzipped, promotor attached, then RNA synthesis at the promotor, and finally DNA zips back up.
Translation is a process in which RNA language is translated into DNA language. The first thing that happened is amino acid attached to tRNA. Then, tRNA attached to ribosomes and later on attached to the mRNA. Next thing that happened is another tRNA comes in and repeat until they make a single RNA, which is the exact copy of the original DNA.
Last but not least is protein synthesis. Protein synthesis is basically meaning the building of protein starting from amino acid, which is the basic single unit of protein, just like carbohydrate is composed of a lot of monosaccharides.
