Answer:
15%
Together, adenine and thymine compose 70% of the segment. This means that 30% of the section is composed of guanine-cytosine pairs. Since these two bases will be equal in quantity, 15% of the DNA section will be cytosine bases.
Answer: Is most likely to result from reduced ATP levels.
Explanation:
Dichlorodiphenyltrichloroethane (DDT) is a colorless, odorless, tasteless, crystalline compound. It is an organochloride. It is used as an insecticide. It is associated with damage of biodiversity and several human and animal health complications.
In human males DDT is associated with decrease in fertility. As it results in low sperm count, negatively affects the sperm motility and synthesis.
The uncoupling process will reduce ATP synthesis in the mitochondrial cells of the sperms. This may lead to low sperm motility in the vaginal canal of the female after the insemination process. Thus this will reduce the male fertility.
1- Preparing the cDNA:
a- Using two different tissue samples (such as control and cancer cells), isolate mRNA.
b- For each sample, prepare complementry DNA (cDNA) from the isolated mRNA. Then fluorescent label cDNA of each sample with a different color and then mixed.
2- preparing the microarray:
a- Bind DNA fragments of different genes to microarray wells.
b- Attach ssDNA (single-stranded DNA) to microarray wells.
3- Combine the probe and the microarray samples:
Add labeled cDNA to the microarray wells.
The correct statement regarding heritability is D. All of the above are correct.
<h3>What is heritability?</h3>
Heritability simply means a measure of how well differences in the genes of people account for the difference in their traits.
