Describe the steps to transcribe an mRNA molecule and use the mRNA molecule to produce proteins.
oksano4ka [1.4K]

Answer:

Explanation:

The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.

In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.

During translation, which is the second major step in gene expression, the mRNA is "read" according to the genetic code, which relates the DNA sequence to the amino acid sequence in proteins (Figure 2). Each group of three bases in mRNA constitutes a codon, and each codon specifies a particular amino acid (hence, it is a triplet code). The mRNA sequence is thus used as a template to assemble—in order—the chain of amino acids that form a protein

But where does translation take place within a cell? What individual substeps are a part of this process? And does translation differ between prokaryotes and eukaryotes? The answers to questions such as these reveal a great deal about the essential similarities between all species.

Vlada [557]

Answer:

C

Explanation:

pyruvate dehydrogenase is the enzyme which catalysis pyruvate to acetyl Co -A. Thus,it  ensures the formation of link reaction/ bridge reaction for linking glycolysis with Citric acid cycle. Therefore, inhibition of this enzyme, prevent link reaction, and there reduction in pyruvate utilization and therefore prevent the  commencements of Citric acid cycle, with consequent  reduction in glucose oxidation. as there is no  reaction of acetyl Co A (from link reaction from pyruvate )   with 4C oxaloacatate in the kreb Cycle to form Citrate in Kreb's cycle. Thus the heart  depends on fatty acid supply for energy.
