Prokaryotic Chromosome
Prokaryotes are organisms that do not have a nucleus and membrane-bound organelles. These consists of bacteria and archaea. These are small, single-celled organisms. A prokaryotic chromosome is circular in structure. It is made up of circular DNA. Most prokaryotes have a single chromosome containing circular DNA. Also, prokaryotic cells are always haploid. They do not have two sets of chromosomes.

- Consider a hypothetical phage whose DNA replicates exclusively by rolling circle replication. A phage with radioactive DNA in both strands infects a bacterium and is allowed to replicate in a nonradioactive medium. Assume that only daughter DNA from the elongated branch ever gets packaged into progeny particles. What fraction of the parental radioactivity will appear in the progeny phage? How many progeny phage will contain radioactive DNA? What is the fundamental difference between the initiation of θ replication and that of the rolling circle?arrow_forwardIf a bacterial chromosome were inserted into a eukaryotic cell, would it be stable? Would it segregate like eukaryotic chromosomes do during mitosis and meiosis? Why or why not?arrow_forwardHigh Frequency Recombination results in which of the following? O 1) Plasmid DNA incorporated into the cell 2) Genomic DNA incorporated into the cell 3) Viral DNA incorporated into the cell 4) Plasmid and genomic DNA from the donor cell is incorporated into the recipient cell's genome 5) The movement of genes within the cell through homologous recombinationarrow_forward
- introns: A)are parts of the new strand replaced with DNA nucleotides during replication B)Are joined together with other introns to make the mature mRNA C)are found in prokaryotic cells D)are binding sites for repressors; therefore introns are involved in controlling gene expression E)do not contain codons or information about proteins; they are removed from the mRNA during splicing/editing of mRNAarrow_forwardA) replicative B) prime C) conjugative D) Hfrarrow_forwardDescribe the four phases of bacterial cell division. Where would horizontal gene transfer occur? Where would sporogenesis occur? If antibiotics generally target cells which are growing and dividing as fast as they can, when would antibiotics be most effective? If a culture had 4 cells to begin with and has a generation time of 60 minutes, how long would it take to get 1,048,576 cells?arrow_forward

O 1) nucleocapsid O 2) prophpage O 3) provirus O 4) lysogenome O 5) chromatidarrow_forward4. Which statement about telomeres is incorrect? A) Telomeres are repetitive nucleotide sequences at- the end of a chromatid B) Telomeres serve as protective caps that prevent chromosome from deterioration during cell division C) Telomeres are gradually consumed during repeated the cell divisions D) In cancer cells, telomerase activity is usually re- duced compared with normal cellsarrow_forward
