PLEASE SOMEONE HELP ME! For a (blank) to be built, the cell needs the instructions in the DNA. DNA is too big to leave the nucleus, son an (blank) copy is made to provide instructions for the protein builders called ribosomes.
First, the DNA will (blank) at the site of the needed gene. The DNA (blank) are exposed. The bases of the DNA code are (blank), (blank), (blank) and (blank). mRNA bases (blank) to DNA bases in order to make a (blank) of the gene.
mRNA also has the base (blank), (blank), (blank), but has (blank) instead of (blank).
The mRNA bases attach to the DNA bases: Guanine matches with (blank), Thymine pairs with (blank) and Uracil matches (blank).
Once the mRNA copy is made, it exits the nucleus and travels to the cytoplasm so the cell can begin to build a (blank).

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.

is this a psat question, if so do not cheat try your best.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's
