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 ...

AQA A-Level Biology Topic 1: Biological Molecules (2022/2023) Already Passed What are monomers? Monomers are *small units* which are the components of larger molecules. What are polymers? Polymers are molecules made from *many monomers* joined together. What are examples of monomers? *Monosaccharides, amino acids* and *nucleotides* What are examples of polymers? *Polysaccharides, polypeptides* and *polynucleotides* What reaction allows two monomers to bond together? A *condensation reacti...

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...

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”...

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...
