Biology First year Important Points

.🧬🧬🧬

Those terms which are mostly used in genetic subject.

🧬1. -🔬
the condition of having only one set of chromosomes per cell .

🧬2. -🔬
the condition of having two sets of chromosomes per cell (2n)

🧬3. - 🔬
a haploid s*x cell in plants and animals (egg or s***m)

🧬4. -🔬
diploid (2n) cell resulting from the union of two gametes in s*xual reproduction

🧬5. - 🔬
the complex of DNA, RNA and proteins that makes up uncondensed eukaryotic chromosomes.

🧬6. -🔬
structures within the nucleus of eukaryotic cells composed of chromatin and visible at cell division (condensed chromatin).

🧬7. 🔬 -chromosomes that are similar in morphology (shape and form) and genetic constitution. In animals one set comes from the father and the other from the mother.

🧬8. -🔬
one of the two halves of a duplicated chromosome

🧬9. - 🔬
specialized constricted region of a chromatid, that contains the kinetochore; sister chromatids are joined at the centromere during cell division

🧬10. -🔬
exchange of genetic material between chromosomes

🧬11. -🔬
the breaking and rejoining of homologous (non-sister) chromatids during early prophase I of meiosis, resulting in recombination

🧬12. -🔬
the pairing of homologous chromosomes during prophase I of meiosis.

🧬13. - 🔬
separation of homologous chromosomes (or sister chromatids) during anaphase.

🧬14. -🔬
the genetic make-up (the assemblage of alleles) of an individual.

🧬15. - 🔬
the physical or chemical expression of an organisms genes.

🧬16. - 🔬
a discrete unit of hereditary information that usually specifies a protein; a region of DNA (locus) located on a chromosome that specifies a trait (characteristic).

🧬17. -🔬
genes governing variations of the same characteristic (trait) that occupy corresponding positions (loci) on homologous chromosomes; alternative forms of a gene.

🧬18. - 🔬
an allele that is always expressed when present.

Chapter # ENZYMES

Main Points to ponder

• Enzymes are globular proteins
• Co factor= bridge between enzyme and substrate
• Non-protein part covalently bonded to enzyme= prosthetic group
• Loosely attached to protein part= coenzyme
• Enzymes simply dissolved in cytoplasm
• Active site of enzymes= binding site+ catalytic site
• pH
• Pepsin 2
• Sucrase 4.5
• Enterokinase 5.5
• Salivary amylase 6.8
• Catalase 7.6
• Chymotrypsin 7-8
• Pancreatic lipase 9
• Arginase 9.7
• Chlorenchymatous cells carry out photosynthesis
• Cell membrane
• 60-80% protein
• 20-40% lipids
• Peptidoglycan= murien
• Large and small subunit of ribosome attachment is controlled by Mg +2 ion
• Old mitichondria digested by lysosomes by autophagy
• Centrioles play a role in formation of cilia
• Undifferentiated cells have 30000 nuclear pores per nucleus
• Erythrocytes have 3-4pores/nucleus
• Chromosome
• Chimpanzee 48
• Onion 16
• Potato 48
