In pea plants, round seeds (R) are dominant to wrinkled seeds (), and yellow seed color () is dominant to green seed color (y).

The
gene for seed shape and the gene for seed color follow the law of independent assortment and are not sex-linked. In a cross between
two RrYy parents, predict the fraction of offspring with round, yellow seeds.

Which step in the PCR program would you have to change if your fragment would have been 10 times longer and how?
bekas [8.4K]

Answer:

increasing extension time

Explanation:

The Polymerase Chain Reaction is a technique widely used in molecular biology laboratories to amplify target DNA regions. The standard steps of a PCR are as follow 1-denaturation, 2-annealing and 3-elongation/extension. These steps are repeated 15-40 times in order to exponentially amplify the linear DNA fragment. It is well known that longer extension times can be used as a strategy to increase the yield of longer PCR products. This is because the extension time depends on the synthesis rate of the DNA polymerase used in PCR technique and the length of the DNA fragment to be amplified.

Help Asap. i also need explanations to go with the answer
nlexa [21]

Answer:

D. In an ocean heated by volcanic activity

Explanation:

Most of Earth was covered in water, early organisms weren't evolved enough to walk on land at the time. There are some organisms that feed off of volcanic activity and use it as an energy resource and would adapt to the heat.

<em>"Hot spots create volcanoes on the seafloor. If these volcanoes rise above sea level to become islands, and if they occur in tropical waters, coral reefs will form on them. Since the volcanoes are cones, the reef forms in a circle around the volcano."</em>

<em>-</em><u>https://courses.lumenlearning.com/earthscience/chapter/ocean-organisms/</u>

<em>"Discovered only in 1977, hydrothermal vents are home to dozens of previously unknown species. Huge red-tipped tube worms, ghostly fish, strange shrimp with eyes on their backs and other unique species thrive in these extreme deep ocean ecosystems found near undersea volcanic chains."</em>

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 <u>TGA</u> 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 <u>TAA</u> G

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

<em />

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

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!

Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of:
SOVA2 [1]
Sister chromosome exchanges are recombination events that occur between homologous chromosomes and are often the result of exposure of the cell to DNA damaging agents. 
Cross over, or recombination, is the exchange of chromosome segments between non sister chromatids in meiosis. Crossing over creates new combinations of genes in the gametes that are not found in either parent, contributing to genetic diversity.
