Does a dog like me? Is scientific or nonscientific
Basile [38]

Answer:

Non scientific.

Explanation:

Whether or not a dog likes you cannot be truly proven, and is more of a subjective query. A dog cannot really like or dislike a person. They can trust or not, they can be loyal or not, dominating or not, and such things, but “like” is an extremely opinionated term.

Compare each patient's cdna sequence to the wild-type cdna sequence. Each patient has one nucleotide-pair substitution mutation.
Lera25 [3.4K]

The mutation is a change in the nucleotidic sequence. In the exposed example, Patient 1: nucleotide 143, T<u>T</u>C⇒T<u>G</u>C. Patient 2: nucleotide 143, T<u>T</u>C⇒T<u>C</u>C. Patient 3: nucleotide 147, TT<u>C</u> ⇒ TT<u>G</u>.

<h3>What is a mutation?</h3>

A mutation is a change or alteration in DNI sequences that introduce new variants.

Many of these are eliminated, but some of them might succeed and be incorporated into each individual.

These mutations are the ones that have been selected by natural selection.

<h3>Solving the problem</h3>

We know that each sequence initiates with nucleotide number 103 and ends in nucleotide 162.

So first, we will number the nucleotides, from 103 to 162. Each nucleotide has a number in increasing order.

Now, we will identify the mutations in each of the strands by comparing them with the wild-type sequence. The mutation occurs in one of the nucleotides, so we must look for the change in the bases.

Finally, we will identify the nucleotide location of each mutation.

                   nucleotide                 wild-type                mutated

<u>                       location                 nucleotide              nucleotide      </u><u>           </u>

Patient 1            143                         TTC                         TGC

Patient 2           143                         TTC                         TCC

<u>Patient 3           147                          TTC                        TTG                         </u>

Hi,

A. Radioactive markers

Explanation

Hershey and Chase used specific radioisotopes to form a trace of the two important components of the virus in its life cycle. The 32P was used to identify the DNA while the 35s labeled the proteins.DNA strands have a sugar phosphate where as protein contains sulfur.

Best wishes!
