The right answer is A codon sequence is incorrect.

Biologists have compared the corresponding DNA and RNA sequences in B cells (white blood cells), the material being provided by various ongoing sequencing projects. They identified more than 10,000 sites where the two molecules differ, with about 40 percent of the genes having at least one transcription error. This error can be found at the level of the codons of the amino acids, which implies a change of one amino acid by another.

DIA [1.3K]
<span>The primary desired therapeutic effect of mannitol is the reduction of intracranial pressure. This pressure, most likely caused by swelling on the brain, is generally caused by head traumas and can be life threatening. The administration of mannitol reduces this swelling thus decreasing the cranial pressure.</span>

denis23 [38]

Answer:

In some mice, fur color is inherited through incomplete dominance. The colors that are possible are black fur, white fur and grey fur. Grey is the trait that is inherited through incomplete dominance. Scenario: a grey fur male mouse and a grey fur female mouse have 8 babies. The offspring that result are: 2 black fur, 5 grey fur and 1 white fur. But this is not what is statistically expected from that cross. Explain why this is still a probable outcome. This is as a result of mutation

Explanation:

Mutation is the sudden change of a gene, from the above explanation mating of an incomplete grey fur dominance with an incomplete grey fur dominance should not have had offspring with 2 black fur, 5 grey fur and white fur. Normal mating should have produced also an incomplete grey fur dominant offspring

m_a_m_a [10]

➜ <u>Mendel conducted breeding experiments with garden peas</u>:

[i] He studied plants (pure) of a tall/short varities.

[ii] He crossed them and obtained F1 progeny.

[iii] He found that F1 progeny was all tall plants.

[iv] He selfed the (hybrid) plants if F1 progeny.

[v] He found that in F2 progeny there were tall as well as short plants.

[vi] The three quarter plants were tall and one quarter was short.

(or any other contrasting character may be taken).

<u>Note</u>: Here, F1 means <u>First fillial generation</u> and F2 means <u>Second fillial generation</u>.
