Explain the role of each of the following in protein synthesis in eukaryotic cells. • RNA polymerase • Spliceosomes (snRNPs) • Codons • Ribosomes • tRNA

The Central dogma includes the replication, transcription and translation.

Explanation:

RNA polymerase; It is invloved in transcription process in which the the squence of DNA is coppied to RNA known as mRNA.

Spliceosomes; The genetic information is in non-continuous form i.e introns (non-codding sequences) are present between exons. These introns are removed by spliceosomes from pre-mRNA.

Codons; Codon is the sequence of three nucleotides on mRNA that code for specific amino acid i.e AUG for methionine.

Ribosomes; These are known as protein factory because protein synthesis take place in ribosomes.

tRNA; It brought the specific amino acids for corressponding codon on mRNA for polypeptide chain.

answer: national resource conservation services

national resource conservation services is the us. based approach that provides technical and financial assistance for natural resource management. nrcs society in conservation of resources by involving in activities like farmland protection, flood prevention, watershed protection, urban conservation, conserves economic and environmental conditions. it conducts soil surveys and implements the policy of natural resources management on the society.
