Structure of Nucleus. - 1. Nuclear envelope: double membrane surrounding nucleus, outer membrane continuous with the (R)ER of the cell. 2. Nuclear pores: allow the passage of larger molecules, such as mRNA, out of the nucleus. 3. Nucleoplasm: granular, jelly-like material making up the bulk of the nucleus. 4. Chromosomes: protein-bound, linear DNA. 5. Nucleolus: small spherical region(s) in nucleoplasm. Manufactures ribosomal RNA and assembles ribosomes. Function of Nucleus. - 1. Controls...

What are aminocyclitols? How do they work? What are they inactive against? correct answer: -aminocyclitols belong to a class of dugs that are sugar-derived and that demonstrate important biological value -aminocyclitols are components that make up aminoglycoside-type antibiotics -they act on susceptible baceria presumably by irreversibly binding to the 30s ribosomal subunit, thus inhibiting protein synthesis. -antimicrobial activity of aminoglycosides is enhanced in alkaline environments. ...

BIO 1A03 McMaster University Test 2 Review Graded A+ Translation Cellular components are able to read the genetic message in mRNA and translate the message into specific primary amino acid sequence of a protein How does tRNA structure allow for SPECIFICTY in translation? 1. Plays critical role in ENABLING the translation of the information 2. Each type of tRNA molecule is not identical and can translate a specific codon into a specific amino acid What is the structure of tRNA? - single RNA str...
