Answer:
Please find the explanation below.
Explanation:
Changes in the genetic sequence of a DNA is called MUTATION. A gene is a segment of the DNA that holds information for the synthesis of proteins, which are responsible for the observable traits in organisms. The expression of a gene brings about the synthesis of a protein that effects a particular trait in an organism. The gene is expressed in two major stages viz: transcription and translation.
Transcription involves production of an mRNA molecule using the encoded information in the genes of a DNA while translation is the synthesis of a protein using the mRNA as a template.
Since, the order of the sequence in a gene determines the order of the sequence in the mRNA which ultimately determines the order of sequence in the protein, a change in the gene of an organism will affect the observed trait of that organism.
More detailedly, a change in the gene will cause a change in the mRNA sequence during transcription. A change in the mRNA sequence will cause a change in the amino acid sequence during translation. A change in the amino acid sequence will affect the protein produced i.e. might not be functional or may not be produced at all. An affected protein will cause a trait in that organism to be affected.
Y = m x + b
m = slope
b = y-intercept
Therefore, the answer is C. <span>The slope is –4 and the y-intercept is 2.</span>
Answer:
The correct answer is "cells which form white colonies on the ampicillin plates".
Explanation:
X-gal staining, also known as blue–white screen, is a common approach to detect colonies that express the gene of interest that has been incorporated into its genome. The basis of this technique is introducing the gene of interest into a vector that interrupts the expression of beta-galactosidase, which means that in a medium with X-gal the cells that were successfully transformed will be white. In this case, the cells that are transformed will also be resistant to ampicillin. Therefore if they growth in a media with both ampicillin and X-gal, a successful clone will form white colonies.
Answer:
A healthy ecosystem consists of native plant and animal populations interacting in balance with each other and nonliving things (for example, water and rocks). ... Decomposers break down dead plants and animals, returning vital nutrients to the soil. Plants take up these nutrients, along with water, through their roots.
