Patho Exam 1 (Maryville University - NURS611) QUESTIONS WITH COMPLETE SOLUTIONSNucleus 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 ...

A level Biology Complete Exam 2023.Purines - ANSWER Bases with a double-ring structure. Adenine and Guanine Pyrimdines - ANSWER Bases with a single-ring structure (cytosine, thymine, uracil) How polynucleotides form - ANSWER mononucleotides join together by condensation reaction between the deoxyribose sugar group of 1 mononucleotide and a phosphate group of another mononucleotide. This forms a phosphodiester bond. Complementary base pairing - ANSWER A complements T (forming 2 hydrogen...

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)...

BTEC APPLIED SCIENCE UNIT 11 Genetics and Genetic Engineering – Learning Aim D. A phosphate group, a sugar, and a base are the three components of a nucleotide. (“What are the three components of a nucleotide - B”) They are sugars and bases that make up DNA and RNA. An organic molecule is referred to as a base. Purines and pyrimidines are the two types of bases. Purines are adenine and guanine, while pyrimidines are thymine, uracil, and cytosine. (“Expand ATP class 12 biology CBSE”...
