There is no requirement that DNA should have a whole number of base pairs per turn. As a thought experiment, say you have a helix of dsDNA with 10 base pairs that completes one helical turn (ie it has 10 bp/turn). Now, twist that DNA along its axis so that it completes 1.5 turns. There is still only 10 bp and thus 6.67 bp/turn (which you should notice is a ...

In germ cells telomerase enzyme is active and elongates telomeres, so youngsters are not born older than their parents due to telomeres. Still, they do receive mutations, accumulated by their parents' germ-line cells, i.e. eggs and sperm. Most of the mutations occur upon division of the cell. Egg cells don't undergo many divisions - they are created in the ...

https://www.rosaceae.org/species/malus/malus_x_domestica/genome_v1.0 You can see the data in the URL above. The details are described in this article. As others said, NCBI seems useful. Go to this site. Chose chromosome you want to see and click genebank or refsequence corresponding to the chromosome in the table (Assembly Unit: Primary Assembly). You can ...

Pattern recognition receptors (PRRs) can potentially discriminate between endogenous and exogenous DNA: Microbial nucleic acids can be discriminated from self nucleic acids using various parameters, such as their sequence, their tertiary structure, their molecular modifications and their localization. In addition, mislocalized DNA and RNA can be an ...

To fully comprehend the concept of wobble base-pairing we need to consider the nucleotide sequences of the anti-codons in the tRNAs that have to "read" the genetic code when the mRNA is being translated on the ribosome. The nucleotide in the anti-codon's wobble position is, for example, often inosine. Under the rules for wobble base-pairing an Inosine can ...

These two concepts are not mutually exclusive. You have constructed a false dichotomy. Both of these facts are true: The electrons in the pi orbitals of the conjugated double bonds in the planar rings are hydrophobic. The nitrogen and oxygen molecules (either in the rings, or as substituents on the rings) can participate in hydrogen bonds. There are ...
