Draw the hydrogen bonds between the bases. The letter R represents the rest of the nucleotide. The bases are positioned approxim

ately as they would be in a DNA double helix. To indicate a hydrogen bond, simply draw a regular single bond between the atoms. Be careful not to modify the existing atoms or bonds in any way, nor add extraneous atoms or bonds. Draw the hydrogen bond(s) between thymine and adenine. Draw the hydrogen bond(s) between guanine and cytosine.

How does a visking tubing differ from a cell membrane<br>Join the following terms:​
musickatia [10]

Answer:

The Viking tubing is meant to be the cell membrane. Glucose manages to move out of the bag and into the surrounding water but starch does not. Not all substances can pass through the cell membrane; some molecules, like starch are too large. The cell membrane is called selectively permeable because of this.

muminat

Answer:

Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway

Explanation:

Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
