Answer:
Topogenic sequences share a series of structural features, and thereby computational algorithms can be used to predict these protein-membrane segments
Explanation:
Topogenic sequences are protein segments formed by alpha-helical transmembrane domains, which are required for the insertion of membrane proteins. These domains share a series of well-defined features: they are composed of segments of about 20 hydrophobic amino-acid residues. In consequence, computational algorithms can be designed to identify protein patterns that fulfill these structural requirements (i.e. segments with a length of 20 residues, hydrophobic level, etc). The models assign a similarity threshold (threshold value) that predict if the similarity level of the protein pattern is good enough to detect a topogenic segment.
I believe it's B. BRCA1 and BRCA2.
Answer:
Cells provide the necessary structural support for an organism.
P.s you should link or photograph the model
Answer:
Enzymes
Explanation:
The regulation of gene expression is the central dogma of life. It is a series or set of mechanisms in which genetic information in the DNA expresses in the form of RNA or protein. Cells give gene expression b different mechanisms as transcription, maturation of mRNA, and translation.
During these mechanisms, different gene-regulatory proteins are influenced. For example, a set of RNA polymerases that are proteins transcribe the DNA molecule during transcription. Transcription factors are also proteins that control the synthesis of proteins in the cell. These proteins are an enzyme that catalyse the gene regulation in the human cells.
Answer: The extinction of dinosaurs will lead to increase in the prey which they used to consume before extinction.
Explanation:
Many years ago the dinosaurs used to dominate on earth as large mammals. They were plant eater herbivores and animal consumer carnivores. After the extinction of dinosaurs the ecological balance got disturbed. Flowering plants dominated the earth. The large and massive non-bird dinosaurs died but the bird like dinosaurs survived and they passed their traits to some lineages of modern birds.
