Answer:
Streak Test
Explanation:
A streak test is used by geologists to help determine the powdered color of a mineral. They usually use a white or black plate, scrape a sample of the mineral onto the plate, and voila!
P.S. I also had a question like this on a test before.
Answer:
Different types of microscopes use different sources for magnification, have different levels of magnification, and can help in visualizing an object in two dimensions or three dimensions.
Thus, if the same object is observed under different microscopes the differences we can observe is the resolution, magnification, and plane (2D or 3D) of the object.
For example, a compound microscope can magnify up to 500x whereas stereoscopic microscope can only magnify up to 50x.
Answer:
The question is incomplete, it lacks the mRNA sequence. The sequence is as follows:
5′−AUGGCAAGAAAA−3′
The answer is Met-Ala-Arg-Lys
Explanation:
Gene expression in living organisms involves the process of transcription and translation. Transcription is the synthesis of a complementary strand of mRNA from a DNA template while translation involves using the transcibed mRNA as a template to synthesize amino acid sequence (proteins).
In the RIBOSOME, where the synthesis of protein occurs, the mRNA nuceleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies a particular amino acid. The collection of all codons is the genetic code. Hence, for a specific mRNA sequence that reads 5′−AUGGCAAGAAAA−3′. The nucleotides will be read three at a time starting with AUG which is a codon that encodes METHIONINE.
Next, GCA is a codon that encodes ALANINE
Next, AGA is a codon that encodes ARGININE
Finally, AAA is a codon that encodes LYSINE.
Hence, the amino acid sequence using the above mRNA sequence, will read: Met-Ala-Arg-Lys
