YACs are used to clone large pieces of DNA in yeast cells. What three types of DNA sequence are required to ensure proper replication and propagation of a YAC in a yeast cell, and what is the function of each?
The three DNA sequence are,
1.replication
2.centromere
3.telomeres
The above are the three DNA sequence that are required to ensure proper replication and propagation of a YAC in a yeast cell.
1.replication is used for DNA replication
2.The function of centromere is to provide a proper segregation of the chromosome at the cell division
3.telomeres is to protect chromosomal ends.

Match the following: Antisense Clone Library Vector A. Pieces of DNA stored in yeast cells ________ B. A population of cells carrying a desired plasmid C. Self-Replicating DNA for transmitting a gene from one organism another D. A gene that hybridizes with mRNA
You are given a flask with liquid media containing a population of S. pombe cells that have a temperature sensitive mutation of a gene that causes complete loss of function of the gene product at the restrictive temperature. The flask had been incubating at the permissive temperature before it was given to you, and the cells in the flask were replicating asynchronously with respect to the stage of the cell cycle. The mutated gene in this strain of yeast encodes...
What could be a consequence of loss of proper p53 function A. Cells fail to progress in the cell cycle at start. B. Mutations accumulate in somatic cells C. M-phase cyclins are inactivated D. DNA replication is blocked
where does transcription begin
3. List the major types of RNA and include what they code for, their function in the cell and which type is translated. 4. If a bacterial protein has 2,500 amino acids long, how many nucleotide pairs long is the ger sequence that codes for it? 5. Where does transcription begin? 6. What is the template and nontemplate strands of DNA? 7. Why is only one strand transcribed, and is the same strand of DNA always...
The abundance of mRNA in mammalian cells is measured to be: a)1% of total RNA content b)10% of total cell content c)80% of total RNA content d)The same as protein content 2. RNAi is used for one of the following purposes. a) To disrupt a DNA b) To clone a particular gene c) To verify the function of a gene d) To produce a new gene To successfully express a protein from a eukaryotic expression vector, the following is NOT...

For answer all questions below part, Ignore question 1. Just
do question 2 and below
Part A: Refer to Lecture 3 & Supplementary Video: https://www.youtube.com/watch?v SiwNtQYLKeU Virtual cloning of the Human p53 gene You are required to devise a set of practical methodologies in order to carry out a relatively simple molecular biology task. 1. You must identify the steps required 2. Formulate a set of practical protocols needed to carry out those steps . Consider...
Consider the three graphs below, which show the quantity of DNA in cells measured by fluorescence in flow cytometry. The x-axis represents the relative amount of DNA per cell, and the relative intensity of the florescence on the y-axis represents the number of cells with that amount of DNA in the cell. Look at the experiment shown on page 248 of your textbook. 1) A B C 2) 20-40,一60一助100 20-40 60一負100 40, 60 N 100 Amount of fluorescence per cell...

MACROMOLECULES: There are 4 types of macromolecules in the cells. Three of them are the product of polymerization processes. Mention what they are. Fill the table with the precursors or monomers, how many of these precursors are there, a drawing of a monomer, the general function of these macromolecules for the cell.
