Explain how water’s polarity is related to its boiling point
Verizon [17]

Answer:

Explanation:

The greater the forces of attraction the higher the boiling point or the greater the polarity the higher the boiling point. ... The other molecules are slightly polar and show the increase in boiling point with molecular weight which is normal. Instead, water boils at +100 C, which is very abnormal.

Hope this helps a little

Answer: A double restriction digest

Explanation: A double restriction digest is a process were two restriction enzymes are used to digest DNA in a single reaction.in double restriction digest you will observe two bands,while in single restriction digest you will observe just one band. In double restriction digest no

Self - ligating plasmid because it create mismatch ends. It also aids in directional in section while single disgestion you have to screen your clones to be sure to get your plasmid with correct insert orientation.

Which is an example of an insertion mutation that changes all of the amino acids that follow the mutation?
astra-53 [7]

Answer:


2) CAG - TTC - ACG mutates to CAG - TTC - ACC - ACG

Explanation:

Insertions are mutations in which extra base pairs are inserted into a new place in the DNA. The number of base pairs inserted can range from one to thousands!

In option no. 1: We see that there is not addition of a single or more than one base, but the new base sequence is different from the original sequence at three places i.e: TTA - CAC - G

In option no. 2: The insertion of three bases ACC has been made exactly after TTC, the whole sequence and arrangement of bases remain same except this insertion.


In option no. 3: The first base of the sequence T is replaced with A, and all other sequence is same. This type of mutation is called substitution in which one base is replaced by other.


In option no. 4: The last base of the sequence C is deleted, and is not present in new sequence. This type of mutation is called deletion in which a base is removed from the sequence.


Conclusion: Therefore, the best option is 2, in which whole codon is inserted in the DNA base sequence.
