Answer:
the answer is c I promise
Explanation:
I just took the test
Answer:
Advantageous
Explanation:
Natural selection acts on traits that are advantageous, thus increasing chances of survival and passing on the trait.
2. The A allele is undergoing positive selection and istherefore adaptive.
3. The a allele is undergoing negative selection anddecreases fitness.
4. The population is undergoing genetic drift.
5. None of the above is false
Answer:
As the change in allele frequency causes the change in genome of the living organism inside few generations.
Explanation:
The effects of change in allele frequency:
The effect may leave the organism with the loss of some genes, while it can effect cause the loss of some of the beneficial genes inside the genome of the organism. Along with that the process can also improve the sequence of genes which are abnormal in nature.
Genetic Drift:
"The change or the evolution inside the alleles frequency of the organisms genome, which may occur due to the chance events."
As the process of genetic drift occurs inside generations, which leaves the random organisms to live.
Answer:
The solution of P. aeruginosa will yield higher Tm value.
Explanation:
The solution of P.aeruginosa contain 68% G+C composition as a result the DNA of P.aeruginosa is more stable than the DNA of mammal contain only 42% G+C composition.G+C composition is most stable because guanine is linked to cytosine by 3 hydrogen bonds whereas adenine linked to thymine by 2 hydrogen bonds.
As P.aeruginosa DNA is more stable than mammalian DNA,as a result the DNA solution of P.aeruginosa will yield high Tm(melting temperature) value than that of mammalian DNA.
b) false
Answer:
true
Explanation:
Because it adapts to the repoducting organism
Intron
Exon
Promoter
9What role does the MutL protein play in DNA repair? (5 POINTS)
It performs a proofreading function, similar to DNA polymerase, and removes incorrect bases from the template DNA strand.
It recognizes and binds to a pair of "mismatched" nucleotides, preventing their translation.
It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired.
It helps to link together regions of DNA, after an error has been removed via exonuclease.
10If a mutation occurs that affects the large subunit of a ribosome, rendering it inactive, how would this affect translation? (5 POINTS)
The small subunit of the ribosome would fail to associate with a mRNA.
Methionine tRNA would not recognize the start codon of a mRNA.
New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.
Arginine tRNA, rather than methionine tRNA, would associate with a mRNA’s stop codon.
8) The region associated with the gene is : ( A ) Silencer
9) The role played by Mutl protein in DNA repair is : ( C ) It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired.
10) The effect on translation is : ( C ) New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.
The silencer is the region of the DNA that regulates the expression of DNA in RNA and protein, since the mutation cannot regulate the expression of genes the region associated with this is the silencer.
Mutl proteins helps in identifying template DNA strand and newly synthesized DNA strand. they are also used in the treatment of methyl mismatch. also
Translation is inhibited when a large unit of ribosomes is affected by a mutation.
Hence we can conclude that The region associated with the gene is : Silencer. The role played by Mutl protein in DNA repair is :It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired.The effect on translation is New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.

Answer:
8- silencer
9- It recognizes the newly-synthesized DNA strand (e.g., by detecting nicks), ensuring only it—and not the template strand—is repaired
10- New amino acids would not be added after the initial methionine, so translation would be effectively inhibited.
Explanation:
Question 8
As the question is, mutation is unable to regulate gene expression and occurs in all cells. Thus, silencer are the DNA control region and regulate the expression of DNA into RNA and protein. Hence, option a is correct.
Question 9
This protein is used to differentiate between tempelate DNA strand and newerly synthesized DNA strand to rectify the foundation incorporated during DNA replication; it helps to identify new synthesizes of DNA. MutL Proteines are a proteins used to treat a methyl mismatch repair system. Hence, option c is correct.
Question 10
If the large unit of ribosome is affected by a mutation, new amino acid is not introduced after inhibition of the original methionine and translation. Hence, option c is correct.
T
F
the first option is correct (true).
the greater the surface area of an object the greater the buoyant force.
Answer:
This is false so option 2 (F)
Explanation:
On edge 2021 it even says false.
