Explain how a change in the amino acid sequence of the FXR1 protein could decrease the ability of the protein to bind to RNA
Likurg_2 [28]

The amount of proteins which is forming the SDS-resistant aggregates is isolated and purified by using the PSIA-LC-MALDI proteomic approach9 specially made for brain tissues.

Explanation:

  • It is known as a regulatory mechanism through which the variations in the incorporation of the exons into mRNA gives  the production of more output which is to related protein, thus results in expanding possible genomic outputs.
  • Amyloids are the β-sheets-rich protein fibrils which can cause neurodegenerative and other incurable human diseases trapping  millions of humans across the world.
  • RNA molecules which are colocalized with FXR1 in cortical neurons are insensitive to the treatment with RNase A.
  • FXR1 also colocalizes in cortical neurons using the amyloid-specific dyes
  • FXR1 is also known to make different forms of RNA molecules and affects their stability and translation efficiency17.
  • To determine the binding energy  of FXR1 with mRNA, the brain cryosections were hybridized with biotinylated poly-dT.

Ivanshal [37]

Answer:

number 1:Charles Robert Darwin was an English naturalist, geologist and biologist, best known for his contributions to the science of evolution. His proposition that all species of life have descended over time from common ancestors is now widely accepted, and considered a foundational concept in science.

2:Charles Darwin's theory of evolution states that evolution happens by natural selection. Individuals in a species show variation in physical characteristics. ... As a consequence those individuals most suited to their environment survive and, given enough time, the species will gradually evolve.

Which of the following correctly describes the appearance of muscle tissue found in the heart? (2 points) Single-nucleus, non-st
muminat

Answer:

The correct option is B.

Explanation:

Muscle tissues of the heart refers to a group of cells that are carrying out similar functions in the heart. There are three different types of muscles, these are skeletal, cardiac and smooth muscles. The cardiac muscles are found in the heart, they form the contractile wall of the heart. These muscle contract involuntarily ( that is, without any external stimulation) and they are single nucleus, striated and short.

Fruit color in a particular plant is controlled by a set of three quantitative traits that work in an equal and additive manner.
Arturiano [62]

Answer:

7

Explanation:

The number of distinct shades of fruit color would be 7. It is given that the color is dominated by a group of three QTL(quantitative traits) with each trait having two alleles(A,a). Out of these two alleles, one represented by a capital letter(A) generates a single dose of yellow pigment while the latter represented by a smaller case letter(a) does not generate any pigment. Since <u>there is no environmental effect, the number of various yellow shades would be 7 through the combinations of yellow and colorless pigments(A/a, A/a, A/a, A)</u>.
