Answer:

Lactose intolerance is when your body can't break down or digest lactose. Lactose is a sugar found in milk and milk products. Lactose intolerance happens when your small intestine does not make enough of a digestive enzyme called lactase. Lactase breaks down the lactose in food so your body can absorb it.

It is the result of a mutated message in your chromosomes. Chromosomes do not just determine how you look but they control all the processes of the cells in an organism.

During translation, the tRNA molecule carrying the correct amino acid corresponding to its anticodon sequence must base pair wit
katovenus [111]

Answer:

The tRNA would be unable to read the mRNA CODON, and will be unable to carry its corresponding amino acid

Explanation:

Protein synthesis occurs in two major stages; transcription and translation. Transcription involves the synthesis of a mRNA molecule while translation involves reading the sequence of the mRNA in order to synthesize amino acids that forms protein. Let's look at translation in details. Translation occurs with the help of a type of RNA molecule called transfer RNA (tRNA) present in the RIBOSOME (site of protein synthesis).

The tRNA possesses a group of three nucleotides called ANTICODON, which it uses to read the mRNA codon that is complementary to it i.e. an anticodon UAC will read mRNA codon AUG. The tRNA binds to the mRNA molecule in order to assess its nuceleotide sequence. Once, a complementary anticodon succesfully reads a particular mRNA codon, it carries the amino acid encoded by the mRNA codon it reads to the growing polypeptide chain. This is the normal translation process.

However, as stated in the question, that if a wrong anticidon successfully binds to a codon. This means that the anticodon that binds to the mRNA codon is not complementary to it. What would happen in this case is that the Anticodon will be unable to read that particular codon it binds to because the complementary base pairing rule is used to read i.e. A-U, G-C. Once, the anticodon cannot read the mRNA codon, the tRNA will also be unable to carry the amino acid that is encoded by that CODON.

in a cross of heterozygous RW four o'clock plants (RW*RW) what proportion of the seeds will grow to produce pink flowers
frez [133]
I am guessing R is pink and W is white so RR an RW is pink so it would be 3 out of every four seeds.

In garden peas, tall plants (T) are dominant to short plants (t), and round pods (R) are dominant to constricted pods (r). A tru
Nataliya [291]

Answer:

Based on the given information, the study of different varieties of the garden pea was done, that is, tall plants with round pods having homozygous genotype TTRR, and the short plants with constricted pods having homozygous genotype ttrr. Post crossing the mentioned varieties of garden pea, the F1 generation comprises tall plants with round pods having the genotype TtRr. While when the crossing of F1 generation plants was done, the plants obtained in the F2 generation demonstrated the phenotype, that is, tall plants with round pods, which is 75 in number and short plants with constricted pods, which is 24 in number.  

This shows that the genes would have been the linked genes, as they would have been situated very close together on the homologous chromosomes, and because of this linkage, the expression of the genes would have taken together.  

In case, if there was no linkage, then the genes would have assorted independently, and the offspring produced in the F2 generation would have shown the phenotypic ratio with the features of tall plants with round pods (9), short plants with round pods (3), tall plants with constricted pods (3), and short plants with constricted pods (1).  

Though the above-mentioned situation did not occur and the plants obtained in the F2 generation demonstrated the phenotype, that is, tall plants with round pods, which is 75 in number and short plants with constricted pods, which is 24 in number. This further puts more emphasis on the fact that the genes for both the phenotypes were linked due to which expression of only the mentioned two varieties took place and the other two failed to do so.

Microevolution…:
Drupady [299]

Answer: Option C.

Macroevolution is a change in allele frequencies within a population.

Explanation:

Microevolution is the change in allele frequencies within a population over time. Microevolution is caused by four processes which are natural selection, artificial selection, gene flow and gene drift and these are referred to as fundament forces of evolution.
