Protein synthesis is a biological process whereby individual cells build their own specific proteins. In the process of protein synthesis, it involves both ribonucleic acid (RNA) and (deoxyribonucleic acid) DNA. This process initiates in cell’s nucleus whereby some specific enzymes unwind the needed part of DNA and makes it accessible and a copy of RNA is made. In transcription DNA double helix which is used as a template is where information of DNA is copied to RNA as one strand.
RNA which are sent to cytoplasm helps to bring components which require for protein synthesis for example ribosomes, amino acids, transport RNA. mRNA is a messenger which is produced in the nucleus when a copy of RNA of protein genetic information encodes in DNA molecule. mRNA exits nucleus and goes into cytoplasm then it interacts with cellular structures called ribosomes and functions as cell’s assemblers in the process of protein synthesis.
RNA molecule or rRNA and proteins are contained in ribosomes whereby rRNA is organized into subunits and mRNA binds to one of the ribosomes sub-unit. mRNA interacts with ribosome sub-unit and makes the approach of another RNA molecule known as RNA or tRNA. tRNA possess a sequence of three bases or anticodon which corresponds codon within the mRNA sequence where elongation takes place. If matching of anticodons of tRNA is found, tyrosine then forms a peptide bond. Amino acids are hydrolyzed from tRNA when protein synthesis is terminated after mRNA is reached
Answer:
maybe 75% of them were purple and 25% were white
Answer:the cell divides by mitosis
Explanation:in this process the cell divides into two identical cells called the daughter cells.the daughter cells end up with the same amount of chromosomes in their nucleus like the parent cells .
Mitotic division involves four stages;prophase, metaphase,anaphase and telophase.
In prophase,the chromosomes shorten and thicken.homologous chromosomes join to become chromatids
In metaphase,the chromatids arrange themselves at the equator of threadlike spindle fibres
In anaphase,the chromatids separated and move to opposite ends of the cell
In telophase, the spindle break down,the chromosomes lengthen and the cytoplasm of the cell divides into two.
this leads to growth and replacement of cells
Artificial wetlands can help purify water and also provide recreational opportunities. They are the major program for replacing lost natural wetlands purify water for use as bottled drinking water are a source of arsenic contamination in Bangladesh are created using xeriscaping methods can help purify water and also provide wildlife habitat.
Approximately eighty seven percent of lung cancer deaths are caused by smoking.
