Toward an Artificial Cell Scientists have recently constructed an artificial ribosome in vitro from purified ribosomal proteins
dalvyx [7]

Answer:

RNAs and proteins can bind via electrostatic interactions, hydrophobic interactions, Hydrogen bonding interactions and base stacking interactions

Explanation:

Proteins bind to nucleic acids (i.e., both DNA and RNA) through different types of interactions:

- electrostatic interactions, also known as van der Waals interactions, refer to attractive/repulsive interactions between molecules depending on their electric charges.

- hydrophobic interactions, i.e., interactions between nonpolar molecules and water molecules

- Hydrogen bonding interactions resulting from the interaction between a hydrogen (H) atom that bind to an electronegative atom (e.g., N, O, F, etc), and another electronegative atom.

- base stacking interactions that result from the arrangement of RNA nucleotides

In this case, it is also important to highlight that the interaction will depend on the specific tertiary structure of ribosomal proteins and ribosomal RNAs (rRNAs).

A scientist begins a PCR with 10 picograms of DNA and allows it to go through three cycles.
BaLLatris [955]

Answer:

b. 80g

Explanation:

Three cycles of PCR would produce 3 doublings of the amount of DNA.

Cycle 1: 10x2  = 20pg

Cycle 2: 20x2 = 40pg

Cycle 3: 40x2 = 80pg

This can also be worked out for large cycle numbers by final mass = starting mass x 2ⁿ, where n is the number of cycles.
