Answer: Mosses gametes are produced by mitosis and ferns gamete are also produced by mitosis.
Explanation:
Mosses and ferns are bryophtes, a group of plants that live in moist habitats and lack true leaves and root.
Mitosis is a form of cell division where a single cell divides to produce two identical daughter cells.
During the life cycle of ferns, the diploid sporophyte produce haploid spores by meiosis. The prothallus of the sporophte produce gametes by mitosis.
In mosses, the diploid sporophyte produce spores from a capsule which open when a small structure operculum degenerates. A single spore germinate to form protenama from which the gametes are produced through mitosis.
Answer:
The correct answer would be 2,70,000 nucleotide long gene.
The gene refers to the protein coding sequence of the (deoxyribonucleic acid) DNA.
The nucleotide sequence of a gene corresponds to the codon sequence if mRNA. The codon sequence of mRNA then codes for the amino acid sequence of the protein.
The codon refers to the set of three nucleotide which codes for a specific amino acid. For example, CAG codes for glutamine, AUG codes for methionine et cetera.
So, if the polypeptide chain consists of 90,000 amino acids then it must contain 90,000 x 3 nucleotides which are equal to 2,70,000 nucleotides.
Answer:
C
Explanation:
Two amoebeas because when a amoebea splits it has the same information copy as its parents
This process is known as meiosis, used to create sex cells.
