Proteins are synthesised only on ER bound ribosomes complexes False True None Identify the correct sequence of DNA packaging? A. Wrapping of DNA around histones to form nucleosomesB. Formation of chromatin fibrC. Coiling CBA CAB ABC BCA None Which of following is NOT true for secondary plant cell wall as compared to primary cell wall? Secondary cell walls are thicker Secondary cell walls are stronger Secondary cell walls are indicator of actively growing cells None of the above None Smoot endoplasmic reticulum is A site of RNA synthesis A site of protein synthesis A site of lipid biosynthesis All of the above None Nucleosome facilitate Site of DNA replication Compacting and packaging of large plant genome Accurate DNA transcription Mitosis and meiosis None What is internode Length of the stem between two nodes Distance of first branch from the soil Length between shoot tip and stem base All of the above, None Why DNA is a genetic material It functions in cell physiology It can be inherited across the generations Because it encodes proteins It is a long molecule None Which of the following cellular component is rich in lignin content?
