A particular triplet of bases in the coding strand of DNA is 5'-CGT-3! Which of
the following is the anticodon component of the tRNA that binds the mRNA
codon transcribed from this DNA?
AdGu 5
B. 3! - UGC-5
3 KGO15
0.3 AG 5

Answers

Answer:

The options to this question are incorrect.

The answer is 5'- CGU- 3'

Explanation:

DNA is the genetic material of living organisms that contains information on how to produce proteins needed for the normal functioning of the cell. This information is encoded in the nucleotide bases contained in the DNA molecule. The information is expressed via the process of transcription and translation.

Transcription is the process whereby DNA is used to synthesize a mRNA molecule. In this case, a particular triplet of bases in the coding strand of DNA is 5'-CGT-3. This undergoes transcription to give 3'- GCA- 5'.

This further undergoes translation with the aid of a tRNA, which carries the following anticodon component which is complementary to the mRNA codon: 5'- CGU- 3'.

Worldwide, renewable energy is the fastest growing source of energy yet it only
provides 10% of our total energy. Explain two positives and two negatives associated
with renewable resources.

Answers

Answer with Explanation:

Positive

1. They don't create too much pollution, which makes them "clean."

It allows us to have a clean air because there's no need of burning them just like the fossil fuels (non-renewable).

2. They don't cost too much to run.

The supply of these resources doesn't cost anything at all. For example, solar energy relies on the heat of the sun. The sun's heat is definitely free and can be found in most sunny places.

Negative

1. Setting up is expensive.

An example of this is the "wind turbine" that costs millions of dollars in order to set up.

2. The output is affected by many factors.

Depending on the kind of renewable resource, most of these are affected by many factors. For example, wind turbines rely on wind's blowing while the hydroelectric powers can be affected by drought.

Can you please help me I am super stuck

Answers

Answer:

a.) 12 Newtons

b.) Same Direction

c.) Unbalanced

Explanation:

The system shows 2 individual forces:

A force of 5 N pulling the box LEFT

A force of 7N pushing the box LEFT

Both forces are LEFT, so they have the same direction.

Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:

Resultant force's magnitude is then: 5N + 7N = 12N

Resultant force's direction: unchanged = LEFT

Since the resultant force's magnitude is not 0, the system is unbalanced.

In tomatoes, the following hypothetical pathway gives rise to different fruit colors. Y gene R gene Precursor substrate Intermediate substrate Product and lacks color and fruit is and fruit is yellow fruit is red green from chlorophyll Mutations in the genes for both of the enzymes produce lack-of-function, recessive alleles. What would be the expected genotypic and phenotypic segregation ratios if you self-fertilize a RrYy individual

Answers

Answer:

Explanation:

From the information given:

The analysis of the hypothetical pathway gives:

                         Y gene                                  R gene

Green fruit            →         Yellow fruit               →           Red fruit.

If RrYy undergoes self-fertilization, the expected genotypic and phenotypic segregation is:

RrYy × RrYy

The progenitors to undergo the segregation are as follows:

                 RY            Ry            rY                 ry

RY             RRYY      RRYy         RrYY            RrYy

                (red)           (red)        (red)            (red)

Ry             RRYy        RRyy         RrYy           Rryy

                (red)         (green)       (red)           (green)

rY             RrYY           RrYy         rrYY            rrYy

               (red)             (red)        (yellow)      (yellow)

ry              RrYy         Rryy            rrYy             rryy

                (red)          (green)        (yellow)      (green)

Thus; the expected phenotypic ratio is:

= 9(red)  : 3(yellow) : 4(green)

The expected phenotypic ratio is:

= 1(RRYY): 2(RRYy): 2(RrYY): 4(RrYy): 1(RRyy): 2(Rryy): 1(rrYY): 2(rrYy): 1(rryy)

Answers

Answer:

Experimental Vaccine Herpes Vaccine = D

Attenuated = B

Purified macromolecule Vaccine = B

Recombinant-Vector Vaccine  = A

Inactivated or Killed = C

Diphtheria Vaccine = A

Explanation:

A Vaccine is an organic arrangement that gives dynamic obtained invulnerability to a specific irresistible infection. A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.

Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).

The administration of Vaccine is called vaccination. vaccination is the best strategy for forestalling irresistible sicknesses

Do you agree that wild species such as orangutans have the right to exist whether or not they are useful to humans? Explain.

Answers

Answer:

Because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas. Unfortunately, deforestation and other human activities, such as hunting, have placed the orangutan in danger of extinction.

Explanation:

Hope this helps ;)

Ape like organisms with red coloured hairs that are mammals and belong to the Hominidae family are called Orangutans. They are found in the rainforests and are 1.2 - 1.8 m in height.

To this open question, I don't agree with the statement.

The viewpoint can be explained as:

They have the right to exist even when they are not useful to humans as they play a vital role in the food chain and the ecosystem in which they reside.

If Orangutans are withdrawn from the ecosystem then many plant species will be impacted or can vanish.

Orangutan helps in seed dispersion and sustain a healthy and balanced condition of the ecosystem.

The residents, trees and the ecosystem are interdependent for survival and hence, they cannot be removed.
