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!

Help me pls I will give brainliest to the correct answerer. Do as much as you can pls

Debora [2.8K]

Answer:

Answer below! : )

Explanation:

Explain 1) The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable. The dependent variable is the variable being tested and measured in an experiment, and is dependent on the independent variable. 2) Testing only one variable at a time lets you analyze the results of your experiment to see how much a single change affected the result. If you're testing two variables at a time, you won't be able to tell which variable was responsible for the result. 3) The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is "controlled" or held constant in the control group 4) Not sure about this one sorry! 5) hypothesizing, observing, and experimenting. 6) This rule says that where you have one situation that leads to an effect, and another which does not, and the only difference is the presence of a single factor in the first situation, we can infer this factor as the cause of the effect. 7) No matter how carefully observations and experiments are performed, it cannot be ensured that every possible factor is the same in every observation. 8) Munsell Charts are used to provide standard descriptions and names of color. 9) Nitrogen, phosphorus, and potassium. 10) Water table, also called groundwater table, is the upper level of an underground surface in which the soil or rocks are permanently saturated with water. 11) Humus significantly affects the bulk density of soil and contributes to its retention of moisture and nutrients. 12) Texture refers to the size of the particles that make up the soil. The terms sand, silt, and clay refer to the relative sizes of the soil particles. The combined portions of sand, silt, and clay in a soil determine its textural classification. 13) The main difference between sand silt and clay is their particle size. Sand particles are larger in size while clay particles are extremely fine, and silt particles are somewhere in between sand and clay particles. Sand, silt, and clay are the main mineral particles in the soil that affect its texture 14) Mineral matter is derived from the constituents of the parent material. Organic matter. The nature and abundance of iron. Moisture content. 15) In some mineral soils aluminum can be dissolved at pH levels below 5.0 becoming toxic to plant growth. Soil pH may also affect the availability of plant nutrients. Nutrients are most available to plants in the optimum 5.5 to 7.0 range. 16) Phosphorus is essential for cell division and growth and promotes plant maturation. 17) Aspect of soil porosity concerns the oxygen found within these pore spaces. All plants need oxygen for respiration, so well-aerated soil is important for growing crops. 18) The ground above the water table may be wet to a certain degree, but it does not stay saturated. The dirt and rock in this unsaturated zone contain air and some water and support the vegetation on the Earth.

I did most of them! I didn't do the "Identify". I hope this helps! : )

Sorry if I wrote a lot!!
