Hi! <span>In the United States, the most common blood type is </span>O<span>, followed closely by type A. If you have type </span>O<span> blood, you can only get type </span>O<span> red blood cell transfusions. But you can give your red blood cells to people with type A, </span>B<span>, </span>AB<span>, or </span>O<span> blood, which is why you are sometimes called a universal donor!
I hope this helped please tell me if i didn't help! :D</span>
Answer:
It only allow certain material to enter the cell
The basic building block of DNA and RNA are Nucleotides.
She will give the DNA fingerprinting report to the jury which will have samples of suspect and its profile matching to the evidence found at the scene of crime.
In DNA fingerprinting hair, blood, semen, or other biological samples are required for the comparison of suspect and evidence. It depends on the unique polymorphism in their DNA.
The fragments of DNA are made to run on the electrophoresis gel and the similar bands observed will confirm the matching.
The DNA fingerprinting will provide very exact evidence if the DNA samples matched.
14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
