Given that the main reason for which an artist will retrace a drawing in pen is to <u>correct errors </u>and achieve a <u>final draft</u>, we can compare this to the biological process of DNA proofreading.
DNA proofreading is a <u>biological process </u>that takes place during the biosynthesis of DNA. During this time, a chain of <u>DNA </u>is read and a complementary chain is creating, <u>effectively duplicating the genetic code</u>.
During this process, DNA proofreading takes place. This is described as a process in which the DNA polymerase retraces the genetic code, detecting and fixing any errors in the synthesis before the strand is closed once again.
The fact is that both processes, despite taking place in astronomically different situations, share a final goal which is to prepare the "product" for the "final draft". This allows us to draw <u>valid</u> <u>comparisons </u>between the retracing of a <u>cartoon </u>and the <u>proofreading </u>of <u>DNA </u>by the DNA polymerase enzyme.

Answer: allele, gene, DNA, chromosome, nucleus
Explanation: An allele is a variant of a gene or a different form of a gene. A gene is a segment of a DNA that codes for an RNA or a protein. A DNA is a genetic material that contains all the genetic information of an organism. A DNA is packaged and condensed into a threadlike material known as chromosome and chromosomes are found in the nucleus of a cell.
A nerve is actually a long threadlike
bundle of dendrites that conduct electrical impulses.
<span>Dendrite word derived from the Greek
word ‘dendron’ which means tree. They carry messages in the form of electrical
impulses to cell body, there are also wire like nerves called axon. Sensory
nerves and motor nerves are common types of nerves.</span>
Answer:
Catabolite repression
Explanation:
Catabolite repression is characteristic for prokaryotic organisms such as bacteria and this is the way to control metabolism.
It is called repression, because enzymes that are involved in other sugar's metabolism are inhibited (repressed). The system of catabolite repression have components such as:
- sensory systems-detects ratios of glycolytic intermediates,
- global regulators-control the expression of genes that encode for enzymes.
