The urine is formed from wastes and extra water filtered or secreted out of the blood.
Answer:
5' AUGUUUGAUCUU 3'
Explanation:
The nucleotide bases for mRNA are Adenine, Guanine, Cytosine, and Uracil. Uracil replaces Thymine (it's DNA counterpart). From this, you can eliminate options C and D.
Then it is just matching pairs: Adenine = Uracil , Cytosine = Guanine.
3' TACAAACTAGAA 5'
5' AUGUUUGAUCUU 3'
Answer:
Single nucleotide deletion
Explanation:
Original DNA sequence:
A T A C G G T A
T A T G C C A T
Mutated DNA sequence:
A T C G G T A G
T A G C C A T C
In the mutated sequence, there is a nucleotide missing. It goes from ATACGGTA to ATCGGTAG. The A nucleotide is gone. This represents a single base pair deletion.
Even though it is only one base, this changes the way the entire sequence is interpreted. The DNA transcribed into an mRNA and then translated into a protein by reading triplet codons which correspond to specific amino acids.
So while the initial sequence would be read as:
ATA, CGG, TA...
The new sequence would be read as:
ATC, GGT, AG...
So the sequence of the protein is completely altered.
Groundwater refers to the water present underground, in the spaces and cracks in the sand, soil, and rock. It is accumulated in and moves gradually through the geologic creations of sand, soil, and rocks known as aquifers.
The groundwater supplies drinking water to about 51 percent of the total population of the United States and 99 percent of the rural population. Almost 64 percent of the groundwater is utilized for irrigation purposes, and it is also a source of recharge for rivers, lakes, and wetlands.
Hence, the correct phrases that describe groundwater are feeds rivers, used for irrigation, and provides drinking water.
