The right answer is The digestion of DNA by restriction enzymes.
The fragmentation of the DNA is done by bacterial enzymes called restriction enzymes.
Restriction-enzymes (or endonucleases) recognize and cut the DNA into a specific sequence. These enzymes are naturally produced in bacteria as a defense against bacteriophages - viruses that infect bacteria. The bacterial restriction enzymes cut the DNA of the invasive bacteriophage while leaving the bacterial genomic DNA healthy and safe through the addition of methyl groups.
These enzymes are used in practice at the laboratory level to explore DNA.
Answer:
Resistance of corn plants to animals
Answer:
a mutation that blocks the GTPase activity of Ras
Explanation:
A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.
As the lines get closer that means that the elevation is getting higher and that is were the mountain or hill starts.
Answer:
a- brown eyes
b- blue eyes
c- brown hair
d- widows peak
e-short arms
f- can roll tongue, long arms
g- brown eyes, brown hair
h- widows peak, short arms
i- brown eyes, can roll tongue
j- brown eyes, brown hair, no widows peak, long arms, can't roll tongue
Explanation:
So the capital letter is the dominant trait, and the lowercase letter is recessive. The capital dominant trait will always overpower the lowercase recessive trait. So the only way the recessive trait can be seen is if there are two together. So... if R is white fur and r is brown fur...
RR would show the dominant trait of white fur
Rr would show the dominant trait of white fur
rr would show the recessive trait of brown fur
