Answer:
a. The allele for round seeds is dominant to the allele for wrinkled seeds.
Explanation:
Mendel found that when two pure breeding plants that differ from each other with respect to one genetic trait are crossed, all the progeny express the phenotype of one parent. The phenotype of the other parent is not expressed in the progeny. He concluded that the genetic trait that is expressed in the F1 generation is dominant over the other which is masked in this generation.
A cross between pure breeding plants for round seeds and the wrinkled seeds obtained all the round seeded progeny. This meant that the phenotype "round" was dominant over the phenotype "wrinkled". If the allele "R" gave round phenotype and the allele "r" imparted wrinkled phenotype, the allele "R" was dominant to the "r".
Answer:
It enters the citric acid cycle and associates with a 4-carbon molecule, forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
Explanation:
Acetyl-CoA(2C) associates with oxalacetate(4C) to form citric acid(6C). Then through redox reactions, CO2 molecules result from decarboxylation (COOH becomes R-(R1)CH-R2). And through dehydrogenation H2 molecules are incorporated in NADH+ in FADH2, resulting in the 4-carbon molecule at the beginning (oxalacetate). That's why it's called a cycle(Kreb's cycle or citric acid cycle)

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).
