A polysome is ____. a. the complex that adds a poly(A) tail onto an mRNA b. an mRNA transcript to which multiple ribosomes
are attached c. the combination of a large and a small ribosomal subunit d. the promoter assembly at the site of transcription initiation e. the complex where mRNA splicing occurs
Answer:b. an mRNA transcript to which multiple ribosomes are attached
Explanation: polysome consist of mRNA complex and two or more ribosome coming together to translate mRNA into a polypetide or amino acid. It helps produce many polypeptide from a single mRNA.
Different ribosomes bind to the mRNA at different time elongating the polypeptide chain. We have the free( non-poly A ) and memberane bound (poly A) polysome.
polysaccharide are formed when dehydration reaction occurs between a large number of monosaccharides. amylose is a polysaccharide compose of between 60 and 300 glucose
