What is the amino acid sequence for the mRNA strand CACCCAUGGUGA?
krek1111 [17]

Answer:

Histidine- Proline- Tryptophan- Stop codon

Explanation:

The mRNA strand in the question is produced as a result of a process called TRANSCRIPTION. However, the mRNA transcript is further used to synthesize an amino acid sequence in a process called TRANSLATION. The mRNA sequence is read in a group of three nucleotide bases called CODON.

Each codon specifies an amino acid which is represented in the GENETIC CODE. In this case, a sequence of mRNA strand is given as: CACCCAUGGUGA

The following codons in the sequence specify the following amino acid:

CAC - Histidine

CCA - Proline

UGG - Tryptophan

UGA - Stop codon

Hence, the amino acid sequence encoded by the given mRNA strand is Histidine- Proline- Tryptophan- Stop codon.

N.B: After a stop codon (UGA, UAA, UAG) is encountered, the translation process stops.

Which technique involves injecting an animal with a radioactive molecule to see which part of the olfactory bulb is most activat
Rudiy27

The asnswer is 2DG also known as 2-Deoxy-D-glucose.  2DG is a glucose molecule that has the 2-hydroxyl group replaced by hydrogen, so that it cannot undergo further glycolysis. As such; it acts to competitively inhibit the production of glucose-6-phosphate from glucose at the phosphoglucoisomerase level (step 2 of glycolysis).

What is used to break the bonds of nodules??
olga_2 [115]
<span> </span><span>Bean roots will have no nodules if there are no compatible Rhizobium bacteria in the soil. The nodule is a symbiotic relationship between the plant and the bacteria. Nitrogen fixing root nodules are pinkish in color. Green root nodules indicate actively reproducing bacteria that are not fixing nitrogen. The number of nodules depends on the amount of innoculant (Rhizobium) available in the soil. Look at the photos and make an estimate like x nodules per y linear inches of root. Hope this helps.

The edible part of the radish root functions as a food storage organ. The string parts of the radish root function as normal roots absorbing water and dissolved nutrients. Bean roots have no modifications for food storage. Radish roots don't have nodules. The radish root is a "tap root". The bean root is a "fiberous root" 

Beans don't grown faster than radishes because of the root nodules. Bean seeds are large. Radish seeds are small. The energy stored in the bean cotyledons helps the seedling get a fast start. The radish gets a slower start from less stored energy.</span>
