What is the minimum number of cycles necessary to replicate a fragment of DNA over 500 times? How did u determine this?

Biology

Answer:

The correct answer is "9 cycles".

Explanation:

The minimum number of cycles necessary to replicate a fragment of DNA over 500 times is 9 cycles. In Polymerase Chain Reaction (PCR) method, the fragments of DNA are doubled in each cycle. This means that after "n" cycles, the total number of fragments is given by the equation 2^n. In this case, after 9 cycles a total of 512 DNA fragments will be obtained, because 2^9 is equal to 512.

frez [133]
Genetic variation results in different forms, or alleles?, of genes. For example, if we look at eye colour, people with blue eyes have one allele of the gene for eye colour, whereas people with brown eyes will have a different allele of the gene

Limestone deposits can help researchers learn about what the area was like
Ivahew [28]

Limestone deposits can help researchers learn about what the area was like  thousands of years ago as Limestone can contain fossilized plants and animals.

Explanation:

  • Limestone often contains fossils of shelled sea creatures. Entire reef formations and communities of organisms are found preserved in limestone.
  • The types of fossils found in limestone include coral, algae, clams, brachiopods, bryozoa and crinoids.
  • Limestone is a sedimentary rock made almost entirely of fossils.
  • Fossils are the remains of ancient plants and animals, like an imprint in a rock or actual bones and shells that have turned into rock. Fossils are found in sedimentary rocks and hold the clues to life on Earth long ago.
  • Limestone is composed of the mineral calcite; calcium carbonate. It often has variable amounts of silica in it, as well as varying amounts of clay, silt, and sand. Limestone rocks fall under the category of sedimentary rocks that are made from mineral calcite.

What results from the addition or deletion of nucleotides in any number except a multiple of 3?
eimsori [14]
Addition or deletion of nucleotides in any number besides 3 results in a "frame-shift mutation."
This is because every 3 nucleotides of DNA/mRNA exons codes for a single amino acid in the synthesis of a protein. This triplet codon theory means that if 3 nucleotides are added or deleted then an amino acid will be added or lost, but subsequent codons and amino acids will still be read correctly.
However, if any number of nucleotides other than 3 are added or removed, then the codons following the mutation will be out of "sync," in terms of the reading order.
Hence it is called a frame-shift mutation because it shift the reading frame when translating nucleic acids into proteins. Frame shifts will lead to the wrong amino acids being adding in the wrong order for the rest of the code after the mutation.
