Answer:

Component of ribosomes: Ribosomes are organelles involved in the protein synthesis they made up of r-RNA and proteins.They play a role in the alignment of amino acids during protein synthesis.

Used in degrading mRNA: SiRNA is small synthetic RNA molecule used for gene silencing experimentsIt is the 18-25bp length and it binds to its complementary m-RNA and degrades it.

Brings amino acid to ribosome:t-RNA is called transfer RNA because it transfers amino acids during protein synthesis. Each amino acid is carried by its particular t-RNA molecule.

Processing of mRNA & Processing of rRNA: Sn RNA is small RNA molecules involved in the splicing and processing of RNA molecules they are located in the nucleus.

Contains codons:m-RNA are intermediate molecules of DNA and protein synthesis and they carry a message regarding the sequence of amino acids. The message carries in the form of codons.

Which of the following best describes how cleaning products like chlorine, hydrogen peroxide, and soap influence the infectious
torisob [31]

Answer:

These cleaning products break apart the capsules of the viruses causing them to no longer be capable of infecting an individual.

Explanation:

Bleach oxidises organic molecules. This causes proteins to become denatured, or lose their shape. The viral capsule containing the DNA is a coat made up of proteins that is required for the virus to become infectious. Therefore, following bleach treatment, the viral protein capsule become oxidised, cause them to loses their shape, meaning the virus can no longer infect individuals.

Identify the interactions as positive, negative, or both.
Mice21 [21]

1. A mudslide wipes out the side of a thriving hill: This is negative as many trees and other organisms will get destroyed.

2. A volcano erupts, covering the nearby land with lava: This is negative as molten and extremely hot lava can cause serious damage to its surroundings.

3. A forest is rapidly growing new plant life: This is positive because new plants are being grown.

4. Humans remove wolves from a national park to protect surrounding homes: This is positive for humans because humans will be safe but it is negative for the eco system as removal of wolves can upset the eco system cycle.

5. A dam is built in the middle of a river ecosystem to supply water to a nearby town: This is positive for humans as a new water resource is being developed for humans but negative for aquatic organisms as the dam can hamper their ecosystem and can cause pollution in water.

Calculate how long it will take for one full base pair mutation to occur. Explain your reasoning with by constructing a mathemat
scoray [572]

Answer:

Since the gene mutates at a rate of 0.76 base pairs every 17.1 million years, to find out the time it would take for 1 base pair to mutate can be calculated by dividing 17.1 million years by 0.76

17,100,000 ÷ 0.76 = 22.5 million years

The following equation can be used to describe this:

μ = [(r2/N2) − (r1/N1)] × ln (N2/N1) = (f1 − f2) × ln (N2/N1)

r1 = the observed number of mutants at time point 1

r2 = the observed number of mutants at the next time point

N1 and N2 are the numbers of cells at time points 1 and 2

Hope that answers the question, have a great day!
