As shown in detail in the absorption spectra, chlorophyll absorbs light in the red (long wavelength) and the blue (short wavelength) regions of the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green
Answer:
<em>The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped. </em>
Explanation:
Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.
A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating deoxythymidine monophosphate (dTMP), which then undergoes phosphorylation to deoxythymidine diphosphate (dTDP), then to Deoxythymidine triphosphate (dTTP), and incorporated into DNA by the DNA polymerase (DNA pol). Thymine in tRNA arises post-transcriptionally, by S-adenosylmethionine-dependent methylation of a uridine 5'-monophosphate (UMP) residue in RNA.
Explanation:
Thymidylate synthase is an enzyme involved in <em>de novo</em> DNA synthesis. This enzyme (thymidylate synthase) catalyzes the transfer of the one-carbon group from 5,10-methylene-tetrahydrofolate (5,10-CH2-THF) to deoxyuridine monophosphate (dUMP) and subsequent methylation to produce deoxythymidine monophosphate (dTMP), which is then phosphorylated to deoxythymidine triphosphate (dTTP) by kinases and incorporated into DNA. On the other hand, specific tRNA methylases catalyze the methylation of transference RNA (tRNA) by using S-adenosylmethionine as a methyl donor. Since tRNA methylation is a post-transcriptional modification, this chemical reaction is considered an epitranscriptomic modification on the RNA molecule.

Carbohydrates give us energy, lipids provide energy, protein builds our structure, and nucleic acid stores our genetic information.</span>
