Final answer:
A nucleotide would least likely contain sulfur, DNA maintains genetic continuity through replication, plant cells feature a cell plate during mitosis unlike animal cells, a chromosome contains genes which consist of DNA, and the correct protein production pathway is ribosomes to endoplasmic reticulum to Golgi bodies to cell membrane.
Step-by-step explanation:
The element least likely contained in a nucleotide is sulfur (A). Nucleotides consist of a pentose sugar, a phosphate group, and a nitrogenous base such as adenine, cytosine, guanine, and either thymine in DNA or uracil in RNA. Sulfur is not a typical component of nucleotides.
The molecule able to maintain genetic continuity through replication is DNA (A). DNA contains the instructions for the synthesis of proteins and can replicate itself to ensure that genetic information is passed down to daughter cells.
In plant cell mitosis, the structure found that is not present during animal cell mitosis is the cell plate (B). This structure forms during cytokinesis, leading to the division of the cytoplasm and the formation of the cell wall between the two new daughter cells.
The relationship among DNA, a gene, and a chromosome is that a chromosome contains hundreds of genes, which are composed of DNA (B). Genes are segments of DNA that carry instructions for producing proteins, and chromosomes are long strands of DNA and associated proteins that contain many genes.
The correct pathway for the production, transport, packaging, and release of a cellular protein is Ribosomes—endoplasmic reticulum—golgi bodies—cell membrane (B). Proteins are synthesized at ribosomes, processed in the endoplasmic reticulum, packaged in the Golgi bodies, and finally released or inserted into the cell membrane.
