Biology
1 answer:
Free_Kalibri [48]3 years ago
5 0

The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.

The quantity and quality of DNA can be greatly improved by performing PCR.

* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.

The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.

How do nutrients get to the cells in a flatworms solid acoelomate body?
wariber [46]
The nutrients get to the cells in a flatworms solid acoelomate body by diffusion process. Flatworms feed primarily on protozoa and bacteria, smaller worms and tiny organisms, dead or alive, that they come across. Based on the species of the flatworms , they also consume plant materials. They rely on diffusion to transport oxygen and nutrients to their internal tissues.

A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred? A.
iren [92.7K]
The answer is <span>C.silent.

Nonsense, missense, silent, and frameshift mutations are point mutations. The point mutations are the change in a single nucleotide base on the DNA molecule. In a missense mutation, the change in a single nucleotide base results in a codon coding for a different amino acid. In a nonsense mutation, the change in a single nucleotide results in a stop codon or in a nonsense codon. Frameshift mutation, due to addition or deletion of a base, results in the change of reading frame and totally different translation. In all these cases, the change could lead to different of nonfunctional protein translation.
Silent mutation, on the other, means that change in a nucleotide base will no affect amino acid. It will result in a different codon, but the one that code for the same amino acid, so the same protein will be produced.
