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!

An example of a community

Lelechka [254]

Answer:

Community, also called biological community, in biology, an interacting group of various species in a common location. For example, a forest of trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.

If the neuron in the figure above is an interneuron where does it send its message

Kipish [7]

Answer: A) Dendrites

Explanation:

Cell body. Also known as a soma, the cell body is the neuron's core.

Axon. An axon is a long, tail-like structure which joins the cell body at a specialized junction called the axon hillock.

Dendrites. Dendrites are fibrous roots that branch out from the cell body.

Dahasolnce [82]

A segmented viral genome can facilitate rapid evolution of new viral strains.

Explanation:

Viruses are non-cellular entities which contain one or molecules of DNA or RNA as their genetic material enclosed inside a protein capsule.

Viruses are obligate intracellular parasites and cannot replicate outside a living cell.

The virus integrates its genome into the host genome and uses its mechanism to replicate its genome.

In other words we can say that viruses actually hijack hosts replication machinery.

The fragment of viral genome which disintegrates itself from the host genome after successful replication might carry fragments of host genome. Thus the viral genome gets modified and may evolve.

The answer is recombination or "crossing over" as some people call it! Hope this helps!
