1. A transgenic organism expresses DNA that has been derived from another species. These organisms have altered genomes and are generated in the laboratory for the purposes of research, for example, the "knock-out" mice are tansgenic mice with a particular gene of interest disabled.
2. Recombinant DNA is the DNA that has been altered to contain genes, or portions of genes, from different organisms. The DNA molecules are formed in the lab using recombination methods to bring together genetic material from multiple sources and therefore creating sequences that are not found in the genome.
3. Restriction enzymes are found naturally in bacteria and they cut DNA at specific nucleotide sequences. These enzymes are also called restriction endonucleases, they cleave DNA into fragments at or near specific recognition sites called restriction sites. They are found in bacteria and archaea and they serve to provide a defense mechanism against invading viruses.
4. Biotechnology is the use or alteration of organisms, cells, or biological molecules to produce food, drugs, or other goods. Living systems and organisms are used to make or develop products. Biotechnology enhances cellular and biomolecular processes to develop technologies and product for the purposes of improving life and health.
5. Polymerase chain reaction is a technique that is used to quickly synthesize billions of copiies of a specific segment of DNA. It is a quick and a very efficient way to generate many copies of DNA. The process is applicable when there are small quantities of DNA to analyze. The events of PCR involves; separation of DNA strands, addition of primers, use of DNA polymerase to produce second strand of DNA.
6. In the process known as transformation, bacteria take up pieces of DNA from the surroundings. Bacterial transformation results from the uptake of naked DNA (DNA without associated cells or proteins). Transformation may also occur naturally in some species of bacteria.
Answer:
Translocation
Explanation:
Changes in chromosome include deletions, duplications, inversions, and translocations.
- Deletion occurs when an end of a chromosome breaks off.
- Duplication is the presence of a chromosome segment more than once in the same chromosome.
- Translocation is when a fragment of chromosomal breakage join a nonhomologous chromosome.
- Reciprocal translocation is a chromosome abnormality caused by exchange of parts between non-homologous chromosomes.
- Robertsonian translocation occurs when two non-homologous chromosomes get attached, meaning that given two healthy pairs of chromosomes, one of each pair "sticks" together.
In the picture attached to this question, the two diagrams above did not show very well but I believe that the first diagram contain four dots, which means that the correct option is A.
Carbon has six electrons, that is why 6 is its atomic number is 6 . In writing electronic configuration, two electrons are usually placed in the most inner shell while the other shells will have 8 electrons each. In the case of carbon which has 6 electrons, only four will remain after 2 electron has been put in its inner shell. Therefore the number of electron in its outermost shell will be four.
Answer:
Option 1, 2, 5
Explanation:
Options for the question
- car a and car b are both moving toward the origin.
- car a and car b are moving in opposite directions.
- car a is moving faster than car b.
- car a and car b started at the same location.
- car a and car b pass each other at the crossover point on the graph. time (s)
Solution -
The motion of any object is represented by position-time In such graphs the position of an object is fixed for any starting point on the y-axis and time on the x-axis.
The slope of such curves determine the velocity of the object at all its position within the graph. The steeper the slope is, the faster the the object is moving.
Hence, the following statements are correct
Option 1, 2, 5
