Answer:
Part A: Thr-Leu-Val
Part B: ACC-UUG-GUU
Explanation:
When you transcribe a DNA sequence to mRNA, you need to remember that in RNA there is no Thymine (T), instead it has Uracil (U). So the base pairings would be like this compared to DNA base pairing:
DNA RNA
A-T A-U
T-A T-A
C-G G-C
G-C C-G
Given the sequence the transcription will be as follows:
DNA : TGG - AAC - CAA
mRNA: ACC - UUG - GUU
Next, to translate it into amino acids, you will use the chart. Now amino acids pair in codons (3 base pairs at a time). Let's take the first codon in your sequence:
ACC
1st 2nd 3rd
A C C
Using the column on the left, find the row that matches it, so in this case A.
At the very top, there is another row of letters, looking at the row of A only, look for the column of the second base which is C.
Lastly, look at the right most column and find the letter that matches the third base within the box where A and C intersect. In this case, C is your third base.
The amino acid where all three intersect is your first amino acid which is Thr.
Just do this for the next codons and you will come up with the answer.
Nonsense mutations make stop codons. If the mutation is towards the beginning of a gene, then the protein that gets created will be cut short and not function properly. But if it was towards the end, there is still a chance that the protein will still be able to work.
Answer:
The observed image will not be sharp
Explanation:
When 100x microscope objective lens is being used, light refraction in the air is enough high to produce image alterations. Image distortions can be minimized by immersion oil because this liquid has a higher refractive index than air. However, light refraction is not usually noticeable when using 4x, 10x and 40x objective lenses. Moreover, this image will not be sharp after putting oil on the slide and going back to the 40x objective, it is for that reason that the 40x is called 'high dry' lens. In consequence, it is required to clean the immersion oil off the 40x objective. In general, it is required to to remove the oil and refocus off the slide and lens immediately after oil immersion (it can be done by using an oil-soluble solvent).
Answer:
Elastomeric
Explanation:
An elastomer is a polymer whose main characteristic is elasticity and can even recover its shape after being deformed
The chemical composition of an elastomer is the grouping of thousands of molecules called monomers, which join together forming huge chains. These large chains of polymers are those that give elasticity since they are flexible and are intertwined in a very messy way.
When an elastomer is stretched, its molecules align, allowing many times to take a crystalline appearance. However, upon releasing the tension, it immediately returns to its original state of elastic disorder. The above distinguishes elastomers from plastic polymers.
