The sequence of nucleotides in a messenger RNA molecule (mRNA) is determined by the sequence of nucleotides in a a transfer RNA
ycow [4]

Answer:

D-DNA molecule

Explanation:

The process of copying the sequence of  DNA nucleotide  sequences to the mRNA is called   Transcriptions. It  is the  first stage in gene expression   for protein synthesis, and<u> it involves the unwinding of the DNA double strands  molecules  by enzyme</u><u> </u>DNA Helicase into two  free strands,(by melting the hydrogen bonds between organic  bases), a process   initiated by the binding of enzymes RNA Polymerase to  the promoter sites on the DNA  template; the alignment of the mRNA  nucleotides on the  single DNA template strands in 3'-5  direction; the formation of  hydrogen bonds between the organic bases  of the template DNA  and   that of the messenger RNA single strands,(  and phosphodiesterbonds  within RNA nucleotide ), to form DNA-RNA complex.

The copying is done in  complimentary anti parallel fashion;5'-3' prime. direction.

 The  hydrogen bonds, between the bases  DNA-RNA complexes breaks,and  the releases  the mRNA  which  exists through the nuclear pores.Thus  this <u>leads to copying of the the coded messages as seqeunce of DNA , from the DNA to the mRNA for gene expressions.</u>

Round the number 14.587020 to 4 significant digits. a. 14.59 b. 14.58 c. 14.587 d. 15.00 Please select the best answer from the
gregori [183]

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59
