"It is the process in which one molecule of glucose is broken in half, ... producing two molecules of pyruvic acid, a 3—carbon compound. HOW does the C811 get glycolysis going? It uses the energy of 2 molecules of ATP."

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!

True or false: surveillance can be performed through either stationary or mobile means.

Ivanshal [37]

This is true. Surveillance can be performed efficiently through both stationary and mobile means. As far as human surveillance goes, people can track other people by tailing them or by using a stationary means such as a stake out. As far as technology goes, there are plenty of mobile devices that can be used for surveillance such as tracking devices. Security cameras can be used for stationary purposes.

Answer:

Evidence of metamorphism can be indicated by flat, horizontal layers within the rock.

Explanation:

Metamorphic rocks refer to rocks that are modified with heat or pressure, which change their physical and chemical properties. The main reason behind this modification is the rearrangement of the mineral crystals, which occurs due to their response to the previously-mentioned properties of heat and pressure.

There could be different types of evidence of metamorphism. However, the main evidence can be indicated by the presence of flat, horizontal layers within the rock, also known as foliation, a process that occurs when the pressure squeezes the minerals, leading to a flat, horizontal layer. Then, scientists could analyze the composition of these layers to identify minerals or even fossils within it.
