Plant cells have a cell wall that is very rigid, which forces the cell to shape that way. Animal cells are round because they don’t have a cell wall only a plasma membrane
Answer: Binge-Eating Disorder
Explanation: Sally did not vomit the food away, and she ate way too much food in a short amount of time, which would be Binge-Eating Disorder.
Answer:
13. both donor DNA and vector DNA are digested with the use of a restriction enzyme that produces sticky ends and then mixed in a test tube to allow the sticky ends of vector and donor DNA to bind to each other and form recombinant molecules.
14. Because all DNA fragments have the same amount of charge per mass, small fragments move through the gel faster than large ones.
15. Gel electrophoresis is a technique used to separate DNA fragments according to their size. DNA samples are loaded into wells at one end of a gel, and an electric current is applied to pull them through the gel.
16. DNA is colorless, so adding tracking dyes to a sample helps you determine the rate of movement of different size protein molecules in the gel during electrophoresis.
17. (A)The function of Taq DNA polymerase in PCR reaction is to amplify the DNA for the production of multiple copies of it (B) Taq polymerase can only make DNA if it's given a primer, a short sequence of nucleotides that provides a starting point for DNA synthesis (C) Primers are the strands of DNA that serve as this initial foundation for the DNA replication process, and they are used to demarcate the segment of the DNA template to be amplified
Explanation:
The rest is in the picture
Answer: depending on the type of chromosomes a and b could be pericentric and paracentric inversions
C. Tandem duplication
D. Reverse tandem duplicate
E. Deletion
Explanation:
In an acrocentric chromosome, a is a type of paracentric inversion which does not involve the centromeres while b is a form of pericentric inversion which involves the centromere. Doubling a particular segment on the chromosome refers to a tandem duplication. Removal of a segment indicate deletion.
