A desert would be a good example because there is no exact source of water there unless you are in a specific one.
Answer:
Explanation:
Detergent enzyme used because The positively charged sodium ions in the salt help protect the negatively charged phosphate groups that run along the backbone of the DNA. A detergent is then added. The detergent breaks down the lipids in the cell membrane and nuclei. DNA is released as these membranes are disrupted.
Proteases catalyze the breakdown of contaminating proteins present in the solution to its component amino acids. It also degrades any nucleases and/or enzymes that may be present in the sample. This is of vital importance since these chemical compounds can attack and destroy the nucleic acids in your sample.
Answer:
This question lacks options, the options are as follows:
A. 3’ ATA GTG CCC AAC GGT 5’
B. 3’ TAT CAA GGG TTG CCA 5’
C. 3’ TAT CAC GGG TTG CCA 5’
D. 3’ TAT CAC GGG TTG CCT 5’
The answer is C
Explanation:
DNA replication is the process by which a DNA molecule makes a copy of itself i.e. duplicated. In this process, the double-stranded DNA molecule splits into two single strands, which each serves as template for the synthesis of another strand. The new strand is synthesized using the COMPLEMENTARY BASE PAIRING RULE.
Complementary base pairing rule states that an Adenine base will always hydrogen bond with a Thymine base while Guanine base will always hydrogen bond with Cytosine base i.e. A-T, G-C. Hence, given the original strand of DNA in this question, the complementary strand will have the following sequence: 3’ TAT CAC GGG TTG CCA 5’
