T TAGCG is repeated many times in human telomeres. On the lagging strand of parent DNA in DNA replication, there is a length unreplicated because it's "too short" to make another Okazaki fragment. As we know, replication on the lagging strand is dictated by Okazaki fragment polymerization by RNA polymerase in the 5' to 3' direction. A good inference based on these interactions is the fact that ...

Question #9e3f6 - Socratic
The best adapted organism survive a pass on their DNA to their offspring creating a change in the DNA of the overall population. This change in the case of superbug results in a population of bacteria that is resistant to antibiotics. This has serious medical implications making diseases caused by the bacteria difficult to control.

A very nice and promising technique, but there are many challenges : prevent an immune reaction that might kill the cell in which the DNA is introduced direct the virus to the right cell type; introduction into reproductive cells is for example usually not desired recombination has to occur at the right location in the genome.

Question #18fd9 - Socratic
DNA polymerase is important because its discovery allowed the invention of PCR (Polymerase Chain Reaction). PCR is an important tool that revolutionized the study of DNA and molecular biology. It allows the duplication of thousands copies of target loci, which are localized strands of DNA, either coding or non-coding. These regions are targeted usually using a couple of primers, small strands ...

Question #ad77c - Socratic
Explanation: DNA : Deoxyribonucleic Acid, is a double-stranded macromolecule, composed of polynucleotides. The polynucleotides are comprised of purine-pyrimidine pairing, bonded together in a large double-helix structure, containing a phosphate-sugar backbone. This macro-structural nucleic acid is termed as DNA. It simply stores all the hereditary information.

Question #99a58 + Example - Socratic
The features are as follows: (i)The codon is triplet. 61 codons code for amino acids and 3 codons do not code for any amino acids, hence they function as stop codons. Examples of a stop codon are UAA, UAG & UGA. (ii)One codon codes for only one amino acid, hence, it is unambiguous and specific. Example AUG- most of the time it codes for methionine. (iii)Some amino acids are coded by more than ...

What is log_e of e? + Example - Socratic
log_ee=lne=1 (ln is a button on you GC, equivalent to log_ee) By definition the log_aa=1, whatever a is. (as long as a!=0 and a!=1) What log_ax means is: What exponent do I use on a to get x? Example: log_10 1000 = 3 because 10^3=1000 So log_10 10 = 1 because 10^1=10 And this goes for any a in log_aa because a^1=a

That is because RNA forms polypeptide chains i.e proteins Proteins form an integral part of every living cell on this planet. Proteins have a huge variety of shape, size and function.Every task in the cell is directly or indirectly related to some or the other protein. Executing a task in a cell is much like retrieving information from a database.DNA acts as a storehouse of information from ...

Question #7828a + Example - Socratic
1) Biotic and abiotic factors together create and define the ecosystem. 2) Furthermore, these biotic and abiotic factors sometimes are mutually interactive and influence each other 1) An ecosystem is characterized by both its biotic and its abiotic factors. For example, if two areas were exactly alike in terms of atmospheric temperature, altitude, insolation, and so on -- but differed only in ...
