Semisolid media such as MIO are used to determine motility. Another such medium such is SIM (sulfide, indole, motility) medium.

Flauer [41]

Answer:

Explanation:

In this specific scenario, seeing since both of the mediums are differential, the bacteria can grow on either of them, therefore either of them would be a good choice. A differential media allows the researcher to visually distinguish which species have the specific biochemical process. Which in this case both options have the ability to allow bacteria to grow which is what is needed.

41) a particular triplet of bases in the template strand of dna is 5' agt 3'. the corresponding codon for the mrna transcribed i

KiRa [710]

A particular triplet of bases in the template strand of DNA is 5' agt 3'. the corresponding codon for the mRNA transcribed is<u> 3' UCA 5'</u>

<u></u>

It serves as a link between DNA's genetic code and proteins' amino acid sequences.

The codons in the messenger RNA (mRNA) are complementary to the nucleotide sequence on the DNA template strand.

Then it controls the synthesis of amino acids with the aid of tRNA and ribosomes.

Its name, messenger RNA, refers to the fact that it carries genetic information. The single strands of adenine, cytosine, guanine, and uracil that make up the mRNA molecule are held together by a sugar phosphate backbone.

Two codons: His, Lys, Phe, Tyr, Asn, Asp, Cys, Gln, Glu, Codons Ile, STOP, and three ("nonsense"). Ala, Gly, Pro, Thr, and Val are the four codons. None of the five codons.

The great scientist Isaac Newton said that his long studies of the moon gave him headaches.What do you think is complicated stud

Oduvanchick [21]

Well, using Math to see how far the Moon is from the Earth could be hard. Also, he saw that the Moon is moving in a "circle" instead of flying off, so the Earth did have a pull on the Moon so that it didn't fly away. Newton had to use Math in order to be able to identify what it's now called gravity. There's a lot that the Moon has to offer, there were no computers back then, so there's was no calculator and everything had to be done by hand.

Free palmitate is activated to it's coA derivative(palmitoyl-CoA) in the cytosol before it can be oxidized in the mitochondria.

n200080 [17]

Answer: hydrolysis of intermediate palmitoyl Co A ,with loss of labeled CoA.before reaching the matrix gives the answer

Explanation:

This is because when the labeled Coenzyme A of the Plamitate combines as Palmitoy-CoA with oxaloacetate to form intermediate (palmitoyl-CoA )in Citric Acid cycle:

CoA is hydrolysed with loss of the labelled CoA which returns to the cystosol. Therefore, the labelled CoA does not reach the matrix of the mitochondrial,but returns to the Cystosol.

Consequently, the CoA in the Cystosol will be labelled in palmitoylCoA and the one in the matrix of the liver mitochondrial will be non radioactive(,will not labelled).
