Recall that dna and rna are synthesized only in the 5'→3' direction and that dna and rna sequences are written in the 5'→3' direction, unless otherwise noted.

consider the following dna sequence:
5' 3'
3' 5'

part a) identify bases in the bottom strand that can be transcribed into start and stop codons. write the mrna sequence (in the form of triplets, for example, ggg-aaa-ccc) that would be transcribed between start and stop codons if the bottom strand served as the template for rna polymerase.

part b) write the amino acid sequence that would be translated from the mrna sequence you just wrote.

enter your answer using 3-letter abbreviations for amino acids as in the example: val-arg-ser-trp

The Transcription mRNA

5'- AUG-CCC-GUU-UGG-AGA-UCG-GGU-UAC-AGC-UAG-3'

The translation product

5' Met-Pro-Val-Trp-Arg-Ser-Gly-Tyr-Ser-3'

Explanation:

Transcription is a process which transcripts the DNA to a molecule called mRNA or messenger RNA which contains code for the synthesis of amino acids.

The RNA nucleotide base pairs are added in the same way as in the DNA that is guanine will bind cytosine but adenine will bind uracil instead of thymine.

Since the start codon is AUG which codes for methionine and stop codons could be UAG, UAA or UGA which do not code for the amino acids during translation.

In the given question,  

Looking for the start codon which is AUG in the template strand is found and the transcript mRNA thus will be coded as

Template strand

3' AACTT- 5'

The Transcription mRNA

5'- AUG-CCC-GUU-UGG-AGA-UCG-GGU-UAC-AGC-UAG-3'

The translation product

5' Met-Pro-Val-Trp-Arg-Ser-Gly-Tyr-Ser-3'

from almost the creation of the first true maps of the earth, people started seeing how continents would be able to fit together.   in particular, people noticed that south america fits almost exactly into africa.

you should be aware that while world maps were around early in the 1600’s and better defined by the end of the 1700’s, those maps were not ‘public’ but were treated as state secrets.   and so it was not till much later that the broader ‘science’ community had access to good quality and accurate world maps.

get the whole story here…

it is now known that most of the major continental masses can be fit together in a jigsaw process.   in fact we now know that the continents were indeed once all joined together as one land mass – the supercontinent of pangaea.

if you look at most world maps you will ponder how this is evidence, as the continents really don’t appear to ‘fit’ together very well.   what you need to understand is that the vast majority of maps are drawn using a map projection that has the north and south poles (which are points) are a line the width of the map at the top and bottom.   this means that the map distorts the true shape of the earth’s land and oceans as you love closer to the poles.     some other map projections distort less, but have the map shape looking like segments of an orange.   see here for a range of map projections.   check out the way greenland changes size in each!

what is more remarkable, is the next piece of evidence when added to the shape of continents.

location of mountains and fossils

what is remarkable, when you reassemble all the continents together, the ancient mountain ranges (many now eroded to their cores) and the location of rock types and fossils all match up.

to this answer it would be edge enhancement
