DNA has two strands. If the sequence of nucleotides of one strand was known, is it possible to use that information to determine
yanalaym [24]

It is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand.

  • Deoxyribonucleic acid (DNA) is a biological molecule with two strands. Each strand is made up of a sequence of nucleotides. The DNA nucleotides are Adenine (A), Cytosine (C), Guanine (G) and Thymine (T).

  • In a DNA molecule, Adenine forms an hydrogen bond with Thymine i.e. A-T, while Guanine forms an hydrogen bond with Cytosine i.e. G-C.

  • Therefore, it is possible to use the information of the nucleotide sequence of one strand to determine the sequence of the other strand. For example, a strand with ATGCGTACGAT will form the following sequence: TACGCATGCTA

hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support
Gwar [14]

Hi,

Harshey and Chase did a great experimentation which was basically a two step experiment to prove that DNA and not proteins are the actual carriers of genetic information from parents to offspring.

  • In the first part of their experiment, they used bacteriophages (virus that eat bacteria). They used radioactively labeled sulphur(35S) medium to grow bacteriophages and observed that all the bacteriophages had proteins with radioactive sulphur(35S).
  • In the next step they allowed these phages to infect bacteria and to their surprise, they found that the bacteria did not had radioactively labeled sulphur in them because the coat of bacteriophage stays outside the body of bacteria when it attacks it. This proved that DNA not proteins were the hereditary material.
  • To make their results more reliable, they did a second experimentation in which, they marked the DNA of the phage with radioactive phosphorus 32P. After labeling DNA, they repeated the same experiment and this time, they found radioactive phosphorus inside the bacteria.

<em>This meant that the bacteria had DNA of phage entered inside them and this again proved that DNA not proteins are the hereditary material. You can see attached image for better understanding. </em>

Hope it help!

What are 3 nonpolar molecules used in everyday life?
Tresset [83]
Three nonpolar molecules that are used in everyday live are carbon dioxide (CO2), methane (CH4), and ethylene (C2H4).

Ethylene is used to make plastic and ripen fruits and methane is used to produce electricity and power garbage trucks. Besides its usage in the crucial processes of photosynthesis and cell respiration that keep us alive, carbon dioxide is important in refrigeration and is also found in fire extinguishers.

Hope this helps!
