Linear chromosomes - Study guides, Class notes & Summaries

Most of the cell membrane's specific functions are controlled by: - Proteins Alcoholic Fermentation is a form of: - Anaerobic Respiration Phagocytosis is a form of: - Endocytosis What is a pyruvate? - Pyruvate is an important chemical compound in biochemistry. It is the output of the metabolism of glucose known as glycolysis. One molecule of glucose breaks down into two molecules of pyruvate, which are then used to provide further energy, in one of two ways. What are the small spher...

Bio Exam 3 Questions and Answers 100% Pass What did Griffith discover in his experiment involving bacteria with capsule (S) and non-capsule (R) strains, and what molecule did Avery, MacLeod, and McCarty identify as responsible for this phenomenon? Griffith observed that DNA could transform bacteria, demonstrating for the first time that genetic material can be transferred through a process called transformation. The S-strain, with a polysaccharide capsule, is protected from the immune...

AQA A-Level Biology. 3.2 – Cells Text Questions and Answers 100% Solved Structure of Nucleus. 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. Chromosomes: protein-bound, linear DNA. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal R...

Eukaryotic Chromosomes - ️️The multiple linear chromosomes in a eukaryotic nucleus are highly condensed Degree of coiling and packing changes throughout cell cycle Interphase: relatively more relaxed = less condensed Mitotic phase: relatively more compact = fully condensed for movement of individual chromosomes during cell division Genome size - ️️The genomes of different species contain different amounts of DNA. The complexity of an organism doesn't necessarily match the amou...

Eukaryotes - ANSWER multicellular, complex organisms, have a proper nucleus containing genome, and organelles (lysosomes, endoplasmic reticular - smooth and rough - golgi complexes, and mitochondria), DNA = contained in multiple linear chromosomes, cells divide using MITOSIS Prokaryotes - ANSWER primitive organisms, much smaller cells, unicellular, no nucleus, genome = in nucleoid, no organelles, DNA = contained in single circular chromosome, cells divide using BINARY FISSION binary fissi...
