G1 Phase correct answer: Preparation for DNA synthesis. Duplicate organelles and systolic compents. (8-10hrs) Cyclin D / CDK 4/6 Checkpoint close to end (RB). S phase costs a lot of ATP. S Phase correct answer: Interphase. DNA replication/synthesis. (6-8 hrs) Cyclin A / CDK2 Between G1 and S correct answer: Cyclin E / CDK2 G2 Phase correct answer: Cell growth to accomodate splitting, enzyme and protein synthesis continue; replication of centrosomes complete. (4-6hrs) Cyc...

Genome - Answer all the genetic material the organism contains Vertical transmission - Answer -from parent to offspring -same species (binary fission) Horizontal transmission - Answer -transfer of small pieces of DNA from one cell to another -different or same species 1) transformation 2) conjugation 3) transduction Transformation - Answer The process of importing free DNA into bacterial cells, cells need to be competent to do this (dead bacteria to live) Dr. Griffith - Answe...

Microbial genomes consist of one or more DNA chromosomes Circular or linear, chromosomes or plasmids Usually one circular DNA chromosome Genome All genetic info that defines an organism Genes Contiguous packets of info encoded on chromosomes A structural gene produces a functional RNA, which usually encodes a protein DNA control sequence Regulates expression of structural gene Doesn't encode an RNA or protein Includes promoters & binding sites for regulatory proteins Ways genome is pac...

It is true that a eukaryotic cell: ○ Is smaller than a prokaryotic cell. ○ Contains structures called organelles. ○ Lacks a well-defined nucleus. ○ Does not contain histones. Eukaryotes are large, have membrane-bound intracellular compartments called organelles, has a well-defined nucleus, and have histones. The function of a histone found in a eukaryote cell focuses on cellular: ○ Division ○ Movement ○ Activities ○ Deoxyribonucleic acid (DNA) folding These proteins b...
