We can't see question five and what's the vocabulary?
Answer:
The question is incomplete, the complete question is as follow:
Thymine in DNA occurs as the result of thymidylate synthase creating _______, which then undergoes _______ to _______, then to _______, and incorporated into D N A by _______. Thymine in tRNA arises ________, by an S-adenosylmethionine-dependent _______ of a ______ residue in RNA.
Answer:
Thymine in DNA occurs as the result of thymidylate synthase creating dTMP, which then undergoes phosphorylation to dTDP, then to dTTP, and incorporated into DNA by DNA polymerase. Thymine in tRNA arises posttranslationally, by an S-adenosylmethionine-dependent methylation of a UMP residue in RNA.
Explanation:
Thymidylate synthase is a key enzyme that catalyzes the synthesis of 2′-deoxythymidine-5′-monophosphate (dTMP) from 2′-deoxyuridine-5′-monophosphate (dUMP). This enzyme catalyzes the addition of a phosphate group (phosphorylation) of dTMP in order to form thymidine 5'-diphosphate (dTDP). Once synthesized, dTMP can be metabolized to deoxythymidine triphosphate (dTTP), which is a precursor for DNA biosynthesis. On the other hand, transfer ribonucleic acid (tRNA) is methylated after the molecule is synthesized. The transfer of the methyl group is catalyzed by an S-adenosylmethionine–dependent methyltransferase that catalyzes the methylation of uridine monophosphate (UMP) using SAM (S-adenosylmethionine) as the methyl donor.
Answer: Chloroplasts are organelles within plant cells that contain chlorophyll and are responsible for carrying out photosynthesis. This process which is utilised by plants to manufacture food, requires carbon dioxide and water which is then converted into glucose and oxygen. Therefore, the release of oxygen tells us that photosynthesis is occurring inside the chloroplast.
Answer:
Please find the explanation below
Explanation:
Transcription and translation are the two proocesess involved in gene expression. These two processes are important because the end result is a PROTEIN responsible for the phenotypic characteristics of that organism. Transcription involves synthesis of mRNA from DNA while translation involves synthesis of protein from mRNA.
In this question, an antibiotics called Puromycin forces the ribosome to detach from the mRNA chain before reaching the stop codon. This means that the antibiotics "Puromycin" abruptly truncates the translation process. Hence, proteins will not be produced. This means that the organism (bacteria) will not be functionally active because of lack of necessary PROTEINS.
Epithelial, muscle, connective, nerve and blood.
