For the polymerization of amino acids to form a protein, one would expect the entropy change in the reaction to be negative . this entropy change is expected because small monomers are joining to form polymer which decreases the degree of freedom.

Negative entropy change occurs when non-spontaneous change occur in the system. It means something which is more disordered will become less disordered hence energy will be required for the process.

As the monomers of the amino acids binds together to form a long polypeptide chain. It will lead to decrease in the degree of freedom of the amino acids molecule. Hence it can be called as negative entropy change.

Whenever monomers are joined together to form a macromolecule it will be show a negative entropy change.

According to studies, 80% of the data that we take in comes from our power of sight. Sight lets us take in 180° of images, perceive 1 million different colors, adjust what we see based on level of light & focus close up or miles away. Our vision is more detailed than any digital camera.

Describe the relationship between gravitational force and distance as shown in the diagram below. SC.6.P.13.2 ​
satela [25.4K]

Let's see the formula

\\ \sf\longmapsto F=G\dfrac{Mm}{r^2}

  • r is the distance
  • G is gravitational constant
  • M is mass of earth
  • m is mass of object.

Hence

\\ \sf\longmapsto F\propto \dfrac{1}{r}

  • If distance is more force is less .
  • If distance is less force is more.

Identify the true statements about RNA interference. Duplex RNA (dsRNA) can suppress the expression of a gene. miRNAs are short,
AlekseyPX

Answer:

- Duplex RNA (dsRNA) can suppress the expression of a gene.

- miRNAs are short, single strands approximately 21 nucleotides long.  

- miRNAs suppress gene expression by interfering with transcription.  

- RNA interference can temporarily suppress the expression of a target gene.

Explanation:

The RNA interference (RNAi) mechanism is a naturally occurring biological process by which an organism suppresses gene expression by using sequence-specific small non-coding RNAs that are complementary to RNA (posttranscriptional silencing) or DNA (transcriptional silencing) sequences. Since its discovery, this mechanism has been exploited in molecular biology to control the expression of target genes. There are different classes of non-coding RNAs which are able to trigger RNAi gene silencing: microRNAs (miRNAs), small interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs, only present in animals), etc. During their functioning, these non-coding RNAs are loaded into the RNA-induced silencing complex (RISC) to direct them to target sequences and trigger RNAi (for example, by cleaving target mRNAs). miRNAs are short, evolutionary conserved RNAs, that associate to the RISC complex in order to trigger both transcriptional and posttranscriptional gene silencing. During their biogenesis, small non-coding RNAs are double-stranded RNA (dsRNA), but they lose a strand (the passenger strand) when associate with the RISC complex, conserving only one strand (the guide strand) that bind by complementary base pairing to target sequences (either DNA in the nucleus or RNA in the cytoplasm).
