How many different arrangement of four bases into triplets can be made

Biology
1 answer:

4^3 = 64

There are 64 ways to arrange the four bases (Adenine, Thymine, Cytosine, and Guanine) into triplets (include repeats of bases as well, for e.g. AAT).

Just in case you are confused by my use of Thymine above, one thing to note is that Thymine will be replaced with Uracil in RNA.

Hope this helps! :)

Nutka1998 [239]

Answer:

  0.625

Explanation:

The slope (m) of a linear regression line is ...

  m=r_{xy}\cdot\dfrac{s_y}{s_x}

Then we have ...

  2.5=r_{xy}\cdot\dfrac{4}{1}\\\\\dfrac{2.5}{4}=r_{xy}=0.625

The value of the correlation coefficient is 0.625.

Sometimes a suffix functions independently as a medical term. give two examples of suffixes that are also terms, and explain how
aleksandrvk [35]

The answer would be –genesis and –gram. 

Suffixes that have a Greek or Latin roots and that are used to combine with other words or parts of words are not called suffixes, these kind of affixes are called combining forms.


One combing form is –genesis.


As an independent medical term, this means the origin of something in medicine. When a doctor talks about the genesis of a contagion, he or she is speaking of the point of origin of a contagion.


-genesis used as a suffix, can indicate a particular process or pathogen. Example is parthenogenesis.


One combining form is –gram.


As an independent medical term, gram indicated the metric weight of an object as a unit of mass. If nurses talk about how much serving of food, they are talking about it in grams.

-gram signifies something written down. Example is pictogram.

Which of the following pairs of base sequences could form a short stretch of a normal double helix of DNA?
11Alexandr11 [23.1K]

Answer:

D) 5'-ATGC-3' with 5'-GCAT-3'

Explanation:

In a double helix DNA, adenine always pairs with thymine and cytosine pairs with guanine. Also, the two strands of a double helix DNA are antiparallel, that is, the 5' end of one strand lies opposite to the 3' end of another strand.

Therefore, a DNA strand with base sequence 5'-ATGC-3' would have a complementary strand 5'-GCAT-3'.

Double stranded DNA: 5'-ATGC-3'                                          

                                      3' TACG 5'

Silver chloride combines with Copper (II) fluoride to yield Silver fluoride and Copper (II) chloride.
MA_775_DIABLO [31]
<h3>Answer;</h3>

2, 1, 2, 1

<h3><u>Explanation</u>;</h3>

Silver chloride reacts with Copper (II) fluoride to form Silver fluoride and Copper (II) chloride.

AgCl (aq) + CuF2 (aq) ----> AgF (s) + CuCl2 (aq)

The balanced chemical equation will be;

2AgCl (aq) + CuF2 (aq) ----> 2AgF (s) + CuCl2 (aq)

Balancing a chemical equation ensures that the Law of conservation of mass is conserved , such that the number of atoms of each element on either side of the equation is equal.
