Answer No 2:
The correct option is C. <u>Substitution of 3rd N-base to go from UCU TO UUU </u>has the potential to cause more damage.
Answer No 3:
UCU codes for the amino acid serine whereas the code UUU is for phenylalanine. A change in this base has caused the entire amino acid to change which will result in the formation of the wrong protein.
Whereas the changes in the base sequence of the options A and B do not change the amino aids being made. Hence, the changes in options A ans B will be less damaging then the option C.
Answer 4:
In the field of genetics, a stop codon can be described as a signal which stops the translation. It is a three nucleotide sequence which is recognized as a terminator.
If stop codon is not present at the right place, then the process of translation will not terminate at the right place and wrong proteins will be made.
The right answer is B.
Nitrogen fixation is done by decomposers that are prokaryotes (bacteria).
<u>Take the example of legumes.
</u>
The different species of rhizobia bacteria, which are able to infect the roots of legumes (Fabaceae family), are specific to certain host plants. Rhizobium phaseoli infects beans (Phaseolus sp).
Bacteria cause the formation of nodules on the roots by penetrating the root hairs, and transform into larger "bacteroids". The nodules are the seat of a symbiotic activity in which the plant provides the sugars and energy from photosynthesis, and in return benefits from the amino acids that are produced there.
Answer:
Many common everyday services such as weather forecasting, remote sensing, GPS systems, satellite television, and some long-distance communications systems critically rely on space infrastructure. Of the sciences, astronomy and Earth science benefit from space technology.
Explanation:
The two types of weather tools are weather balloons and reliable sources
