1.Write the functions of nuclear pores.
2.Which part of the nucleus acts as a site of ribosome formation?
3.List the two components of chromosomes.
4.Classify cells based on the number of nucleus.
Answers
Answer:
1.It controls the passage of substances to the inside or outside of the nucleus. It helps in the transport of proteins and RNA from the nucleus to the cytoplasm and also transport the carbohydrates, signaling molecules and lipids moving into the nucleus.
2.In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome.
3DNA. and proteins.
4.they are classified as prokaryotes and eukaryotes
Answer:
1) It controls the passage of substances to the inside or outside of the nucleus. It helps in the transport of proteins and RNA from the nucleus to the cytoplasm and also transport the carbohydrates, signaling molecules and lipids moving into the nucleus.
2) The nucleus contains the cell 's DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs. Chromatin consists of DNA wrapped around histone proteins and is stored within the nucleoplasm.
3) Chromosome is the compact and organized structure made up of DNA and proteins. So, the major components of chromosomes are DNA. and proteins.
4) The nucleus is a membrane-bound organelle that contains cellular DNA. Some cells, such as yours, contain a nucleus. Other cells, such as bacteria, do not. The nucleus-containing cells are called eukaryotic cells.
