A key feature of all nucleic acids is that they have two distinctive ends: the 5' (5-prime) and 3' (3-prime) ends. This terminology refers to the 5' and 3' carbons on the sugar. For both DNA (shown above) and RNA, the 5' end bears a phosphate, and the 3' end a hydroxyl group.

Another important concept in nucleic acid structure is that DNA and RNA polymerases add nucleotides to the 3' end of the previously incorporated base. Another way to put this is that nucleic acids are synthesized in a 5' to 3' direction.

A parallel beam of white light is incident normally on a diffraction grating. It noted that the second order and third order spectra partially overlap. Which wavelength in the third-order spectrum appears at the same angle as the wavelength of 600nm in the second order spectrum? sOlution?

Adenine Thymine Cytosine Guanine

There is a bit of a degenerate nature, as some codes code for the same protein. In DNA ACTG are used, however in RNA ACUG are used, with Thymine swapped for Uracil :)

1.The genetic code is universal,meaning to say that the 20 amino acids in any organism code for the same protein.
2.It is also punctuated which means that it has a start codon as well as a stop codon.
3.Non-overlapping,the base sequence on one codon cannot be used to form another codon.
5.Triplet code,consisting of three bases

2016 was extraordinary, but how are you feeling about your 2017?
I'm feeling lucky! It'll be good.
I'm nervous but I'm going to be OK.
There is lots to do - I'm already exhausted!
