Answer:
b. Their presence is evidence of a defect in DNA replication, and therefore proof that a given disease is present
Explanation:
Single nucleotide polymorphisms (SNPs) result from point mutations and correspond to the position where there is alternation of nucleotides A, C, G, T at a minimum allele frequency of 1% in a given population. SNPs can be present in both coding and non-coding regions of the genome. As a nucleotide alternation is the result of a defect in DNA replication and these defects cause syndromes and diseases; we can say that single nucleotide polymorphisms are evidence of a defect in DNA replication and therefore proof that a particular disease is present.
Answer:
The need for resources will make the organisms competitive in their ecosystems.
The answer would be D, the carbon-12 atom.
Answer:
The animal cell includes: a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes
Explanation:
These are all the structures of a basic animal cell, depending on which grade you are they get more complex. If so, then you can just ask me!
Hope this helps! :)
When the Bicoid protein is expressed in Drosophila, divisions between cells in the embryo are not yet fully developed. This helps to explain that (B) Bicoid protein diffuses throughout the embryo in a concentration gradient.
Bicoid protein acts as a morphogen. This means it shows its effect when the concentration gradient is high. Also abbreviated as Bcd, the protein helps in establishing the anterior and posterior region of the Drosophila. It also represses the translation of caudal mRNA.
Embryo is the initial stage of a microorganism, right after the fertilization. In vertebrates, this stage does not last much longer because the development of organs begins.
