is dna helicase synthesized by free floating ribosomes
Answers
Explanation:
Ribosomes are small structures within biological cells that function in protein synthesis. Proteins are essential for a huge range of activities within an organism, from catalyzing metabolic reactions and protecting against infection to providing shape and structure. Protein synthesis has several different stages, and ribosomes, which may be free or membrane-bound, are an essential part of the pathway.
Ribosome Structure and RNA
Ribosomes consist of two basic components, a large component and a small component, made up of RNA molecules. RNA is similar to DNA but is single-stranded and shorter in length with slightly different chemical components. DNA enables the first stage in protein synthesis -- transcription -- which takes place inside the cell nucleus. This produces a type of RNA known as messenger RNA, or mRNA. Ribosomes then convert mRNA into protein, in a process known as translation.
