Answer:
Equipment: Thermal cycler is a technology that can change the temperature of the DNA segment. A thermal cycler can raise and reduce the temperature quickly. This allows the PCR process to happen over and over again.
Tools:
Taq polymerase build complementary DNA strands
DNA primers attach to each end of the target sequence
DNA nucleotides or dNTPs make up the DNA
Explanation:
Explanation:
These questions are related to the extraction of DNA using detergents and ethanol.
1. Consistency and texture- the extracted DNA is white, spongy and moist or slime in nature.
2. Salt is used during the extraction process as the DNA is negatively charged molecule and to neutralize the negative charge which will allow the formation of precipitate.
3. The DNA is soluble in aqueous solution as the DNA is a negatively charged molecule therefore the negative charge makes it a polar molecule and it can form the interactions in the aqueous solution.
4. RNA could be present in the aqueous solution along with the DNA as both are the nucleic acid.
5. The base-pairing rule was suggested by the Chargaff who proposed that Adenine binds thymine and guanine binds cytosine.
5. The binding of adenine to thymine involves two hydrogen bonds and between guanine to cytosine involves three hydrogen bonds.
They have different versions of the gene for bristle thickness that connect together to make the bristle thickness in general.
It’s like when you have 6 toothpicks and combine two together, you’ll have 1 really thick one and the others will be small.
