How can point and frameshift mutations contribute to biodiversity of Earth? Explain your<br> answer.
Blizzard [7]

Answer:

<u><em>These mutations form new alleles that increase genetic variation in a population. This variation may lead to new species which increases biodiversity.</em></u>

Explanation:

Mutations are randomly occurring modifications that exist within the genetic code, leading to replication errors in DNA. DNA molecules are long-chain, helical macromolecules that store genetic material. They consist of different monomer sequences called nucleotides. In a reading frame, which contains instructions for protein production, they shape base pairs and codon sequences.

Single nucleotide polymorphisms are normal, as silent mutations, which sometimes result in no changes in amino acids. Some mistakes add a random nucleotide (SNP) in point mutations resulting in new alleles.

Frameshift mutations occur from nucleotide insertions or deletions that are not divisible by 3. This results in the codon requiring more or fewer nucleotides which disrupt the reading frame, resulting in a separate protein translation.

How can I prove Creationism is true in an essay?
snow_tiger [21]
“In the beginning God created the heavens and the earth.” (Genesis 1:1, NIV Bible). All around the world, there is controversy over what is right and what is wrong when it comes to Creation versus Evolution. I strongly believe in Creation. Starting with the first and strongest piece of evidence brought forth by these scientists is that apes used to roam the earth and then later on developed into humans. Evolutionists believe that all human life forms originated from apes, because humans and chimps share close matching Y-Chromosomes. But recent studies have shown that they are actually quite different. This is the first way Creationists can prove Evolutionary Scientists wrong. Another aspect of Evolutionists idea of humans coming from apes is what they call “fossil men”. (matthewmcgee.org). Fossil men are the skeletal remains of humans recovered by Evolutionary archeologists. In order to uphold their evidence of humans coming from apes, when reconstructions of the skulls were being performed, the performing artist would ad chimp-like features that didn’t exist, as a way to help them prove their case. But when the same skulls were examined by unbiased scientists, they found many astonishing differences. In textbooks, Neanderthals are always drawn with excessive body hair, causing them to look like chimps. But when studied, scientists found that the soft parts of the face of these figures left no markings on the skull, proving that they really didn’t look like that. They also stated that with these chimp-like features that the skulls possessed, the hunched posture proved without a doubt that they were chimps. But later on, after examining the skeleton again, evidence of arthritis was found, explaining away all of the Evolutionary scientists theories on Neanderthals. But the truth of Creation is that “So God created man in His own image, in the image of God He created them, male and female, He created them.” (Genesis 1:27, NIV Bible). Creationists believe, and can prove through the teachings in God’s Word, those humans—male and female—were made in the image of God, not in the image of apes. Now after proving the case that Creation is the one and only true answer to the formation of the earth and everything on it, and the universe and everything in it, and having proven numerous times, the multiple times that the frauds of Evolution has been exploited, it has now been made perfectly clear that Creation is the truth and Evolution is the myth.
