As an environment changes, and some organisms have a higher fitness than other, natural selection acts directly on
olga2289 [7]
Natural selection acts directly on those gene variations for traits or phenotypes.
The phenotype of an organism is the physical characteristic and is determined by the organism's genotype. Natural selection selects the genes that produce a certain phenotype by providing suitable conditions for a certain phenotype.

In which order will free nucleotides add on to a single strand of DNA with the sequence ATTGCA during DNA replication?
AnnZ [28]
The answer is T A A C G T.

Replication is a process in which DNA molecule is copied, and thereby two identical DNA molecules are produced.  Complementarity is achieved through interactions between nucleobases. In the DNA, base complements are adenine - thymine (A-T) and guanine - cytosine (G-C). 

So, free nucleotides will add in the following order <span>T A A C G T:
original strand                 new strand
     A                                       T
     T                                       A
     T                                       A
     G                                      C
     C                                      G
     A                                       T</span>

What might hershy and chase have concluded if they had found 35s instead of 35p in bacterial cells? Explain your answer
kaheart [24]

Hershey and chase have concluded that DNA is not protein it was the genetic material.

Explanation:

Hershey and chase said that DNA is not protein it was the genetic material. They took a direct physical approach in finding the genetic material. They both determined that a protective coat was formed around the bacteriophage.

The internal DNA is not a protein, a genetic material. They used label to find it. The lack of 32p labeled DNA remaining in solution after bacteriohages are allowed to absorb the bacteria showed tha DNA was transferred into the bacterial cell.

The radioactive 35s in the solution shows that protein coat protects the DNA before adsorption.
