B. sex chromosomes
C. dominant chromosomes
Answer:
Nucleic acids and lipids.
Explanation:
Biomolecules may be defined as the organic molecules present in the living organism that plays the important role in their growth and metabolism. Four important biomolecules are carbohydrate, protein, nucleic acids and lipids.
Carbohydrate is the polymer of sugars. Amino acids are linked together to forms the proteins. Nucleic acids are the polymers of the nucleotides. Lipids constitute of the hydrocarbon chain and hydrophilic carboxylic acid group.
Thus, the answer is nucleic acids and lipids.
Answer: DNA transcription
Transcription is the process where RNA is created from DNA using RNA Polymerase. This creates an mRNA strand carrying genetic instructions which will be translated into a protein during translation.
The process of creating RNA from DNA is known as transcription. This process involves an enzyme known as RNA Polymerase which unzips the DNA's double helix structure to use one strand as a template for building an mRNA molecule. The constructed mRNA molecule carries genetic instructions from the DNA and these instructions will subsequently be read by ribosomes in the protein synthesis process, also known as translation.
Transcription can be divided into three main stages: initiation, elongation, and termination. During initiation, the RNA Polymerase attaches to a specific area on the DNA strand. For elongation, the enzyme moves along the DNA template, synthesizing a new mRNA strand in a 5' to 3' direction. Once the RNA Polymerase encounters a termination signal on the DNA, transcription stops, and the mRNA molecule is released.

B. meiosis.
C. crossing-over.
D. replication.
Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created, hence option B is correct.
Male and female gametes combine during fertilization to create a diploid (i.e., having paired chromosomes) zygote.
Sex cells are used in the cell division process known as meiosis. To create four haploid daughter cells, a single diploid sex cell splits twice (meiosis I and meiosis II).
Given that the number of chromosomes in the parent cell is cut in half during meiosis, the process is frequently referred to as reductional cell division.
Haploid cells in plants result in haploid gametophytic generations, also known as gametophytes. Gametes eventually develop from the gametophytes.
Therefore, gametes are produced by the process of meiosis.
