What is the main component of the cell and what does it contain? - The nucleus; it contains the nucleolus What is the nucleolus composed of(4)? - RNA, Most of the cellular DNA, DNA-binding proteins, & histones What do histones do and why are they important? - They regulate DNA activity. -Histones bind to DNA and fold it into chromosomes for cell division. -DNA chain in eukaryotic cells are extensive so risk of breakage is high What are ribosomes? - RNA-protein complexes (nucleoproteins)...

Patho Exam 1 (Maryville University - NURS611) Already Passed Nucleus Contains the nucleolus, a small, dense structure composed largely of RNA; most of the cellular DNA; and the DNA-binding proteins, the histones, that regulate its activity. Therefore, the histones binding to DNA cause DNA to fold into chromosomes. The wrapping of DNA into tight packages of chromosomes is essential for cell division in eukaryotes. Ribosomes RNA-protein complexes that are synthesized in the nucleolus and secreted...

Deoxyribonucleic Acid (DNA) - ANSWER-A double helix with two polynucleotide chains held together by hydrogen bonds between specific complementary base pairs that carries genetic information. The pentose sugar in DNA is deoxyribose. Ribonucleic Acid (RNA) - ANSWER-Short, single stranded polynucleotide that transfers genetic information from DNA to the ribosomes. Ribosomes are formed from RNA and proteins. The pentose sugar in RNA is ribose Nucleotides - ANSWER-The monomers that make up poly...
