Answer:
A. Endomembrane system is involved in the production of proteins and how they are transported into membranes, organelles or out of the cell. They are also involved in metabolism and transportation of of lipids; and neutralising poisonous substances. Membranes are connected either through physical continuity or through vesicles (i.e. sacs made of membranes). Thus, endomembrane system consists of nuclear envelope, endoplasmic reticulum, golgi apparatus, lysosomes, vacoules and plasma membranes. Endomembrane system is not found in prokayotic organisms.
B. After enzyme has been coded for in the nucleus and successfully transcribed in the nucleus; and translated in the cytoplasm, the enzyme will be transferred from endoplasmic reticulum to golgi apparatus, where it is modified and packaged to exit the cell membrane for desired destination.
Eubacteria are considered to be “true bacteria”. They are characterized to a lack of nuclear membrane, single circular chromosome and have cell walls composed of peptidogycan. A popular classification system divides all living beings into three domains: Eubacteria, Archaea, and Eukaryotes Hope this helps!
Base substitutions, deletions, and insertions are the three different forms of DNA mutations.
A mutation is a long-lasting alteration to the DNA's nucleotide sequence that can occur during replication and/or recombination. Damaged DNA can change by base pair replacement, deletion, or insertion. The majority of the time, mutations are benign, unless they result in tumor growth or cell death. Cells have developed systems for repairing damaged DNA due to the deadly potential of DNA mutations.
Different Mutations
Base substitutions, deletions, and insertions are the three different forms of DNA mutations.
1. Base Replacements
Point mutations are single nucleotide replacements; you may recall the point mutation Glu ——-> Val is the culprit of sickle cell anemia. There are two types of point mutations, the most prevalent of which are.
Transition and Transversion.
