DNA; genome d. cDNA; start of mRNAThe number of Chromosomes in the human gene is ___.The region of a chromosome that encodes a single protein is called a _________, each of which can have more than one variation, these different variations are called _________.
- Observe the process of transduction in the image below. Cell 1 is represented by "A," Cell 2 is represented by "B," and Cell 1's DNA is represented by "a." The blue color represents the components of the bacteriophage. 6 Process of transduction. A B m с D 5 Which of the following correctly identifies a process that occurs during transduction? um No n During meiosis, crossing over occurs, which combines the genetic information of Cell A and Cell B. Genetic information is being transferred between bacterial cells using a pilus. Bacterial chromosomes are independently sorted into the bacteriophages. n Cell A's DNA was inserted into Cell B and incorporated into the genome of Cell B.The microscope image above shows the human chromosomes from a white blood cell. To create the image, researchers put cells in culture under conditions that encourage the cells to divide. They bathed the cells in a hypotonic (low salt) solution, which caused the cells to swell until their plasma membrane burst open. They "squashed" the chromosomes to spread them out, and stained them with a dye to make them visible under the microscope. Human chromosomes are numbered from longest (1) to shortest (22) plus the sex chromosomes X and Y. In the image chromosome 1 is about 7 micrometers. Answer the following questions. 1) What word(s) in the description above indicates that the chromosomes are not from a cell undergoing meiosis? 2) Based on the size, shape and appearance of the chromosomes in the image, in what cell cycle stage was the cell that the chromosomes came from? How can you tell? 3) Does the image suggest that centromere sequences are always located in the middle of a…Which of the following statements about genomic libraries and cDNA libraries is TRUE? O a genomic library contains exons only O a cDNA library is derived from chromosomal DNA O a genomic library is made using reverse transcriptase O a genomic library is derived from mRNA O a cDNA library is derived from mRNA and is made using reverse transcriptase

However, during development, some cells develop into skin cells while others develop into muscle cells. How can the same genetic instructions result in two different cell types in the same organism? Thoroughly explain your answer.we are learning about the challenge of folding the 6 billion base pairs in the chromatin into the tiny nucleus. It doesn't just have to fit, you have to be able to find what you need! What do you think of this explanation? Some of the structure is conserved across species and some structure changes cell to cell. Can you explain that?
