Because Thymine is "replaced" with Uracil, the corresponding RNA Code for AAT would be UUA.

Answer:

Asparagine (symbol Asn)

Explanation:

In a gene, groups of three nucleotides (such as AAT) form codons that are read during translation, for the  synthesis of proteins.  The way codons are read can be found in a genetic code (attached here).

Before that, the DNA seuqences are transcripted to RNA sequences in order to be read and translated in the ribosome.

AAT (DNA sequence) will be transformed to  AAU during the transcription of DNA.  This is because during the transciption process all thymines (T) are replaced by Uracils (U).

In the genetic  code you can see that AAU is read as Asparagine.

Explosions can occur when electricity ignites explosive gases in the air, such as pure oxygen, methane, or natural gas. true or
victus00 [196]

Answer: True

Explosions due to electricity occurs due the passage of electrical current into air, this results in the transfer of energy from electricity to air. Electrical energy   being a stimuli activates the molecules of air which leads to explosion. An explosion is a rapid event which involves release of energy in the form of gases and also destruction of surrounding entities. For explosion suitable fuel and combustion gases are required. Methane and natural gases acts as fuels whereas oxygen which facilitates combustion of these fuels.

Which of the following continents was not covered by ice during the Pleistocene ice age?
s2008m [1.1K]
I think the correct answer from the choices listed above is option C. The continent that was not covered by ice during the Pleistocene ice age. This is because the southern location of this nation made it much harder for ice to form, even during this time. Hope this answers the question.

<u>r</u>                       rr                  rr

Genotype of the mother with freckle trait is rr. This means that it is a recessive  trait.

Genotype of of the father having clear facial skin is Rr, showing that it is a dominant trait. There can be two genotypes for this trait that is Rr and RR.

When these parents are crossed, they produce 50% offsprings with the freckles trait (rr) and 50% with clear facial skin ( Rr).

Therefore, the likelihood of the first child with freckles is A
