Concept explainers
To determine: The principal conducting cells in the xylem.
Introduction: The process of plant embryogenesis takes place after the fertilization of an ovule to produce a completely developed plant embryo. It establishes the apical–basal axis of the plant, with a root apical meristem at one end and a shoot apical meristem at the other end.
To determine: The principal conducting cells in the phloem.
Introduction: The plant body is formed of individual cells that are organized into aggregations of cells called as tissues. In plants, the cells of each tissue function as a unit.
To describe: The characteristics of each cell type in phloem and xylem.
Introduction: The ground tissue system is formed of collenchyma, parenchyma, and sclerenchyma. The vascular tissue system is formed of phloem and xylem tissues.

- Molecular Biology Explain/discuss how “slow stop” and “quick/fast stop” mutants wereused to identify different protein involved in DNA replication in E. coli.arrow_forwardMolecular Biology Question A gene that codes for a protein was removed from a eukaryotic cell and inserted into a prokaryotic cell. Although the gene was successfully transcribed and translated, it produced a different protein than it produced in the eukaryotic cell. What is the most likely explanation?arrow_forwardMolecular Biology LIST three characteristics of origins of replicationarrow_forward
- Molecular Biology Question Please help. Thank you For E coli DNA polymerase III, give the structure and function of the b-clamp sub-complex. Describe how the structure of this sub-complex is important for it’s function.arrow_forwardMolecular Biology LIST three characteristics of DNA Polymerasesarrow_forwardMolecular Biology RNA polymerase core enzyme structure contains what subunits? To form holo enzyme, sigma factor is added to core. What is the name of the structure formed? Give the detailed structure of sigma factor and the function of eachdomain. Please help.

- Molecular Biology You have a single bacterial cell whose DNA is labelled with radioactiveC14. After 5 rounds of cell division, how may cells will contain radioactive DNA? Please help. Thank youarrow_forward1. Explain the structure and properties of atoms and chemical bonds (especially how they relate to DNA and proteins). Also add some pictures.arrow_forward1. In the Sentinel Cell DNA integrity is preserved through nanoscopic helicase-coordinated repair, while lipids in the membrane are fortified to resist environmental mutagens. also provide pictures for this question.arrow_forward
