The myelin on myelinated neurons can be degraded or destroyed in diseases such as multiple sclerosis-a process called demyelinat

Mazyrski [523]

Answer:

<h2>The speed of action potential propagation get slower down</h2>

Explanation:

Myelination is the process of generating myelin in neurons. In CNS, oligodendrocyte make the myelin sheath.

The main function of myelin is to increase the speed of electrical impulses along the myelinated fiber.

Myelinated fibers lack voltage-gated sodium channels along the myelinated internodes, having them only at the nodes of Ranvier though which the molecules moves.

Demyelination is the loss of the myelin sheath, result due to some neurodegenerative autoimmune diseases, resulting in the decrease of the speed of action potential propagation.

How many possible open reading frames (frames without stop codons) are there that extend through the following sequence? 5'... C

fenix001 [56]

Answer:

There are 4 reading frames without stop codons.

Explanation:

1) To find the possible reading frames you need to separate your sequence in codons (trios) for the 5'-> 3' sense, first, excluding the first nucleotide, then excluding 2 nucleotides and then not excluding nucleotides.

5'... C TTA CAG TTT ATT GAT ACG GAG AAG G... 3' NO STOP CODON

5'... CT TAC AGT TTA TTG ATA CGG AGA AGG... 3' NO STOP CODON

5'... CTT ACA GTT TAT TGA TAC GGA GAA GG... 3'

2)Then you find the complementary sequence (which you already have)

3'... GAA TGT CAA ATA ACT ATG CCT CTT CC... 5'

3'... GA ATG TCA AAT AAC TAT GCC TCT TCC... 5'

3'... G AAT GTC AAA TAA CTA TGC CTC TTC C... 5'

3) Next, you have to obtain the reverse complementary

CCT TCT CCG TAT CAA TAA ACT GTA AG NO STOP CODON

CC TTC TCC GTA TCA ATA AAC TGT AAG NO STOP CODON

C CTT CTC CGT ATC AAT AAA CTG TAA G

4)Now you need to find start (AGT in terms of DNA) and stop codons(TAA, TAG, TGA, also in terms of DNA), in 5->3 and de reverse complementary.

As you can see, you have for open reading frames that lack of stop codon, unfortunately, they also lack of AGT, the start codon.

I added a table where you can find thestart and stop codons as well as the proteins that they translate to in terms of RNA.

I hope you find this information interesting and useful, good luck!

What are abiotic factors? how can they affect the population dynamics? give some examples?

Alisiya [41]

Abiotic factors are things that aren't living that effect an environment, like pH (how acidic the soil is), the temperature, amount of light, and so on. These can effect a population by making it more difficult to survive, perhaps creating more competition over available resources and so on. So for example, if the soil is really acidic in an area, a population of plants may not be able to grow well in that environment.
