Answer:

The right answer is C.

Explanation:

Tautomeric shift type of mutation that happens spontanously by intramolecular proton (hydrogen ion) shift. Guanine and thymine normally found in their keto form but rarely they can be also found in enol forms. Moreover, while adenine or cytosine are normally found in amino forms they can rarely switch into their imino forms by intramolecular proton shift (see figure).

olga2289 [7]

Answer:

The correct answer is -

1. protein synthesis or central dogma

2. leads to changes in the structure by changing in the codes which results in a decrease or loss of function.

Explanation:

1, Protein is made from the information coded in DNA base sequences by the two process protein synthesis that is also called central dogma. The two-process involve in this are transcription involves encoding the information present in DNA by mRNA molecule that codes the information in complementary sequence to DNA. which is then moved out of the nucleus and perform the translation with help of tRNA and ribosome to code the amino acid with help of triplet codes present in mRNA. These amino acids chain are called proteins.

2. Mutations can lead to change in the base sequences or deletion of the base which affects the structure of the protein and also leads to changes in an encoded protein or to a decrease or complete loss in its function or expression. Mutation can damage the cell or organism as it affects the gene expression of all cells of organisms.

Can someone please help me answer questions 16-20 please. Thank you!!
torisob [31]

Answer:

16) 6 electrons

17) 6 protons

18) 6 neutrons

19) 4 electrons

20) 6

Explanation:

There are 6 electrons on the rings in total and 6 protons inside the nucleus. If you count the black cir les, there are 6 of them so there are 6 neutrons. Knowing that the inner ring can only hold 2 electrons the most, 6-2= 4. So there are 4 electrons on the outer ring. Knowing that you can get the atomic number based on the number of protons an atom have, the at pool mic number would be 6.
