Answer:

3 nucleotides in an RNA molecule.

Explanation:

Protein synthesis in the cell produced by RIBOSOMES requires a lot of energy and it's has the highest mass in living organisms. Protein synthesis involve the process where Messenger RNA (MRNA) message is converted to a polypeptide product. The transcription in the cell produced messenger RNA. The translation of mRNA template converts nucleotide-based genetic information into a protein product. The protein sequences contain about 20 Ami o acids and each amino acids is defined by three nucleotides sequence which is called triplet codon. The relationship between nucleotides codon And amino acids is called genetic code

Arrange the events in the life cycle of mosses in the flowchart below. Start the life cycle with the mature sporophyte stage in
labwork [276]

Answer:

Life cycle of a moss

Explanation:

LIFE CYCLE OF A MOSS FROM MATURED SPOROPHYTE STAGE

An embryo further develops into a pear-shaped  sporangium, which is the *sporophyte  stage of the plant*. The sporangium  contains spore sacs, each of which is the spore mother cell that undergoes meiotic division  to form four spores,The spores are released and germination

takes  place giving  rise to a protonema, which develops into a new gametophyte plant. The gametophyte  generation or haploid phase of the moss is from the production  of haploid spores after meiosis  to the period just before fusion of the haploid antherizoid or haploid ovum. The sporophyte generation or diploid  phase is from the diploid  mother cells just before meiosis.

Examples of moss plants include Funaria hygrometrica, Polytrichum commune, Barbuda Indica.
