1. Initiation: ribosome assembles itself around mRNA and first tRNA attaches at start codon
2. Elongation: tRNA transfers amino acid to next tRNA, amino acids attach, and ribosome shifts by one codon so first tRNA detaches. This continues and forms an amino acid chain.
3. Termination: when tRNA encounters a stop codon, the process ends and polypeptide chain is folded into final form.
Answer:
The correct answer will be option-C
Explanation:
Replication is a complex process which makes copies or replicates the DNA in every organism present on the Earth. Replication is an ATP dependent process which is catalysed by several enzymes including DNA helicase, polymerase, primase.
During replication, the two strands are synthesized from parent strand in which the strand which is synthesized in 5' to 3' direction is known as the leading strand which is continuous whereas another strand synthesized in 3' to 5' direction is known as lagging strand as it is produced in the lags.
Since in the leading strand DNA polymerase adds nucleotides at 3' end, therefore, it requires only one RNA primer which assists DNA polymerase to proceed the reaction whereas in the lagging strand since the strands are synthesized in the lags so possess many RNA primers so that DNA polymerase can bind.
Thus, option-C is the correct answer.
The main source of carbon dioxide in an ecosystem is the carbon dioxide gas present in the atmosphere. This carbon dioxide is used by the plants and animals in different ways.
The plants use this carbon dioxide to perform the process of photosynthesis.This is carried out by the help of green pigment called chlorophyll that absorbs light from the sun, water from soil and carbon dioxide from atmosphere.
The carbon in animals comes when they eat these plants.
The spiral usually begins with an increase in demand. The direct effect of this increase is that the producers (of commodities) raise prices to continue to make a profit. It usually begins with a rise in production costs.
