The amino acid sequence for the following DNA sequence is Met-Ser-Cys-His.
<h3>What is transcription and translation?</h3>
Transcription is the process of conversion of genetic information carried by the DNA into messenger RNA (mRNA).
- Sense strand of DNA is the one which runs in 5’ to 3’ direction and carries the information while antisense strand runs in 3’ to 5’ direction and serves as a template.
- E.g.: Antisense strand 3′−TACAGAACGGTA−5′
mRNA sequence 5’−ATGTCTTGCCAT−3’
Translation is the process of conversion of information carried by the mRNA into an amino acid sequence.
- The genetic code is read as a sequence of 3 nucleotides together at a time and is called codon.
- For example: 'ATG' is a start codon coding for methionine.
Here, mRNA sequence 5’−ATGTCTTGCCAT−3’
Amino acid sequence: Met-Ser-Cys-His

Answer: By looking at all the age population pyramids, this would be my best guess. Every territory is different with various populations, however, to the best of my knowledge, it would be the expansive pyramid.
Explanation: Expansive population pyramids are used to describe populations that are young and growing. They are often characterized by their typical ‘pyramid’ shape, which has a broad base and narrow top. Expansive population pyramids show a larger percentage of the population in the younger age cohorts, usually with each age cohort smaller in size than the one below it. These types of populations are typically representative of developing nations, whose populations often have high fertility rates and lower than average life expectancies.
Answer:
Your answer is B) Mutations lead to genetic variation.
Think of it like this, when rays were first starting to develop, they probably started with only one kind, stingless. Somewhere down the line, the genes of the rays started to mutate and eventually, there were stingrays and stingless rays. Now at this point there are predators that frequently feast upon the rays, so which of the two rays are more likely to defend themselves, and get away to live long enough to reproduce and pass on their genes? The stingrays! The mutation that may have occurred millions of years ago, has determined which organisms were more fit for a changing environment.
After seeing a graph represented below, I have recognized the correct answer, and I think that the statement concerning the oxygen level in the lake which can be inferred from the graphs is being revealed by the option 1 -<span>Trout and whitefish require higher oxygen levels than do carp. As you can see the oxygen line on the graph shows that carp does not require as much oxygen as whitefish does require, as level is increasing on the left side.
Hope you will find it helpful!
