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).
The general definition of a gene is some heredity that is passed on from a parent to an offspring. Scientifically speaking, the transfer involves a sequence of nucleotides that forms part of the chromosome. This sequence of nucleotides is a DNA.
Thus, the answer would be
A. a segment of DNA
Answer:
The correct answer would be "The female cone releases its seeds and new sporophytes grow".
Conifers are sporophytes with two types of cones; pollen cones and ovulate cone.
The pollen cones are smaller in size and produce microspores which would develop into the pollen grains.
The ovulate cones are larger in size which produce megaspores which would develop into ovule.
The two gametes fertilized to produce a diploid zygote which develops into the embryo.
The fertilization takes place in the ovule and thus, embryo or seed is developed in the female cone.
The female cone then releases its seed which grows into a new sporophyte.
