Answer:

Freon

Explanation:

<em>Freon is a trademark name for halocarbon (specifically, fluorocabon) products that once served (and still serve in some cases) as refrigerants. They are no longer utilized as refrigerants due to their negative effects on the environment and the ecosystem in general.</em>

<em>In addition to being used as refrigerants, freons are also used as aerosol propellants in cosmetics and household sprays.</em>

Help me find the mutant RNA for the Mutant DNA. I can find the amino acids I just need the mutant RNA
mr Goodwill [35]
With this information I don’t fully understand the question but broadly speaking any sequence that would not made transcribed into the correct RNA from the DNA will be
mutant.

Example is the first normal DNA is read 5’ - GGT 3’ and the RNA will be 3’CCA’ 5’ as it is COMPLEMENTARY. (Important keyword with this)

If the assignment wants you to have a silent mutation that Change the RNA to something that is not complementary to the DNA but will still produce that same protein as the example above. If you need to make a new protein change the rna so the codon will make a different protein from the above sequence

Systematists have used a wide variety of traits to reconstruct the phylogenies of particular groups of organisms. Which one of t
NemiM [27]

Answer:

All of the above traits combined

Explanation:

Phylogeny is an evolutionary history of development of a certain species or taxonomic group.

The purpose of phylogenies is to represent evolutionary relationships among a group of organisms.

During the reconstruction of phylogenies. Systematists often use a variety of traits in order to produce a good estimate of a phylogeny.

The use of molecular traits, gross morphological traits, behavioral and biochemical traits  combined can give a good estimate of a phylogeny.

What is the new peptide chain when the new dna segment is translated for 3'- TACAGGGTGCTACCCACT-5'
kakasveta [241]

Answer:

Methionine- Serine- Histidine- Aspartate- Glycine- stop

Explanation:

Translation, which occurs in the ribosomes, is the second stage of protein synthesis where mRNA transcript is used to synthesize a peptide chain that eventually forms a protein. The mRNA sequence is read in a group of three nucleotide called CODON. Each codon specifies a particular amino acid, which is read and added to the growing peptide chain.

In this question, a DNA sequence reds 3'- TACAGGGTGCTACCCACT-5, the

mRNA sequence from this DNA during transcription will be:

AUG UCC CAC GAU GGG UGA

From this mRNA sequence, the peptide chain that will result following translation is:

Methionine- Serine- Histidine- Aspartate- Glycine- stop
