Answer: It proposes that the entire double‑stranded DNA molecule serves as a template for a whole new molecule of DNA.
Explanation:
In semi-conservative DNA replication:
- a parent double-stranded DNA splits in two.
- Each strand serves as template, and then read by the enzyme, DNA polymerase, to ensure accurate synthesis of a new daughter strand for both
- the newly synthesized strand contains nucleotides that are complimentary to free nucleotides present in the parent strand.
Thus, because the parent double strand is retained in the newly synthesized DNA, this model is described as semi-conservative
Degeneracy
Degeneracy simply means that most of the amino acids produced during protein synthesis from DNA is coded by more than one codon. A codon is a sequence of 3 <span>nucleotides that codes for a specific amino acid.
Because more than 1 codon can produce the same amino acid, the chances of having the synthesis of proteins affected by mutations (i.e. point mutations) is decreased. For example, if the codon with the nucleotide series GAA, which codes for the amino acid glutamate, becomes the codon GAG, the codon will still produce glutamate because the code is degenerate. </span>
Answer:
96000YEARS
Explanation:
Given that 1/28 = 8 half lives
this means that 8 half lives ,
and the given fossil should have 1/28 of the isotope
8 half lives = 1200 x 8
= 96000years
therefore the predicted Neandertal fossils is 96000years
Answer:
Paleontologists may start their investigations by reading articles from the fossil record found in a specific region
Explanation:
Dina may examine the paleontological evidence that includes the study of the fossil record found in her hometown (or closest regions). Moreover, Dina may read research articles on the phylogeography of the species in this area, this information may also help to understand the past climatic conditions
Answer:
Maintaining a rich variety of genetic material that can lead to discoveries useful for humans can be ensured by preserving biodiversity.
Explanation:
Options for this question are:
- <em>Preserving biodiversity
.</em>
- <em>Increasing cloning
.</em>
- <em>Asexual reproduction
.</em>
- <em>Selective breeding.</em>
Biodiversity refers to the number of different living organisms that exist, and which are the product of evolution, those that have multiple ways of interacting, shaping life on the planet.
The human being is part of biodiversity, considered a natural heritage of the world and an element that provides balance to the biosphere.
An important characteristic of biodiversity is that it contains the different genetic information of each living being, each one of which is a functional element on which the maintenance of life on the planet depends, as well as the reservoir of the world's genetic potential, so it is necessary to guarantee its preservation.
