Most cell types are very permeable to water. an exception is cells of the distal nephron, which can be either impermeable or permeable, depending upon the absence or presence of aquaporins.
You don't show the picture, but I can give you an overview.
A frameshift mutation is anything that puts the regular order of 3 nucleotides (a codon) out of it's norm. If these things happen, then you get a frameshift.
Note: This occurs in the gene - not outside of the coding sequence:
1. Loss of a single basepair (perhaps the A in bold):
ATG AAA ATT CTG CCC T...
ATG AAA TTC TGC CCT ....
The codons after AAA are now completely different so this will result in a different amino acid pattern and thus a completely different polypeptide (protein) that may nor may not be functional.
2. Loss of two basepairs (so perhaps 2 of the A's)
ATG AAA ATT CTG CCC T...
ATG AAT TCT GCC CT....
3. Gain of 1 base pair will also cause problems:
ATG AAA ATT CTG CCC T...
ATG AAA AAT TCT GCC CT...
4. Gain of 2 base pairs will also cause problems:
ATG AAA ATT CTG CCC T...
ATG AAA AAA TTC TGC CCT...
If you will make a Punnett square for this problem it will look like this:
T t
t Tt tt
t Tt tt
So the genotype in the first and third box would be Tt. On the second and fourth box, we have tt.
So your answer would be: C. 1 = Tt; 2 = Tt; 3 =tt; 4 = tt
Answer:
True
Explanation:
Usually, dominant traits will show more often because they are, well, dominant. For example, BB and Bb would both show up with dominant traits. It would be required for all lowercase bs in order for a recessive trait to be seen.
