Anton van Leeuwenhoek is a scientist who saw cells soon after Hooke did. He made use of a microscope containing improved lenses

that could magnify objects almost 30ox. Under these microscopes, Leeuwenhoek found moving objects that he named “animalcules,” which included protozoa and other unicellular organisms, like bacteria. He was also able to observe red blood cells and sperm cells. To which of the tenets of the Cell Theory did Leeuwenhoek make the biggest contribution?

A template strand of DNA contains nucleotides in the following proportions: 14% adenine
MAXImum [283]

Answer:

The proportions of  nucleotides in the newly formed complimentary strand will be:

14% Thymine (T), 33% Adenine (A), 21% Guanine (G), 32% Cytosine (C).

Explanation:

In a double stranded DNA, the nucleotides of one strand binds with nucleotides of another strand through hydrogen bonds.

Adenine binds with thymine by two hydrogen bonds (A=T) and guanine binds with cytosine by three hydrogen bonds (G≡C).

So, the complimentary strand must have

  • thymine equal to the amount of adenine in template strand.
  • adenine equal to the amount of thymine in template strand.
  • guanine equal to the amount of cytosine in template strand.
  • cytosine equal to the amount of guanine in template strand.
