What are the three dominant classes of RNA molecules in cells? Which one of these three has the longest RNA molecules, and which has the shortest RNA molecules?

How are RNA molecules synthesized in cells? Draw the chemical structure of a single elongation event. Explain how the synthesis of RNA molecules is terminated in bacterial cells. What modifications are added to an mRNA in eukaryotes after the mRNA has been transcribed?

How would you distinguish a mesotrophic lake diatom assemblage from a eutrophic assemblage in a sediment core?

1. Do monocots have compound leaves? If not, why?

2. Is there a significance of compound leaves relative to strong winds? How about to leaf-eating animals?

1. EMSA (gel shift) and DNase I footprinting both analyze DNA:protein interactions. What is the major difference? Why would a researcher choose one method over the other?

2. Gene expression activity is determined by analysis of both RNA levels and proteins levels. Why would one be used over another? Are they both accurate measures of expression?

species name, who collected, habitat information

A recessive allele in mice results in abnormally long necks and sometimes death during embryogenesis. Crosses were made between pure breeding normal mice and pure-breeding long neck mic. All of the F1 mice had normal necks. Following an F1 x F1 cross, the F2 data below was observed for all mice born alive.

1044 Mice with normal necks

123 mice with long necks

How many total mice were expected in the progeny?

The answer is 348, how do we get this answer ?

Sexual selection on traits involved in mate choice can lead to complex patterns of genetic variation in populations. The African Great Lakes contain a stunning diversity of cichlid fish species, which have recently evolved due to a combination of ecological adaption and sexual selection. In one recently evolved species, we observe the following pattern: An autosomal (not sex linked) locus “X” involved in pigmentation has different effects in male fish than female fish. There are two alleles in this system. In males, “x” acts recessively to produce bright red gill markings, while in females, the same allele acts dominantly to produce a dull striped pattern. A survey of male fish reveal that 56.25% have bright red gill markings.

A.)If we assume the population is in H-W equilibrium, what percentage of the female fish do we expect to have the dull striped pattern?

B.) In the scenario above, the phenotypic effect of alleles at locus X is dependent on the allelic state of the sex determining locus in these fish. What is the term for this kind of genetic interaction?

Question: 1: In certain cases it's legally and ethically appropriate for health professionals to proceed with a treatment without consent or proceed with a treatment that is against the patient decision, give your opinion in detail and examples.

-> In some cases, it is legally and ethically appropriate for health professionals to proceed with treatment without consent or proceed with a treatment that is against the patient's decision.

As based on my opinion it is absolutely acceptable in some cases, as we know in some cases there have some ethical issues in India working with human cells (like cloning or gene modification etc).

But in some cases like for example, a patient who has a critical fever for some days and is under treatment in a hospital, accidentally he has positive in corona virus because of symptoms are relatively the same, that treatment will also proceed against the patient's decision.

-> Capacity means the ability to use and understand information to make a decision and communicate any decision made. A person lacks capacity if their mind is impaired or disturbed in some ways, which means they are unable to make a decision at that time.
