Genes specify proteins via transcription and translation Wha

Genes specify proteins via transcription and translation. What are genes? What is gene expression? b. What do transcription and translation do? c. What is transcription? What is translation? d. What is mRNA? What does it do? e. What is a ribosome? What does it do? f. What is the genetic code? g. How many bases correspond to an amino acid? h. What is a codon? If you were looking at an mRNA and saw the codon AUG, what would you conclude about it?

Solution

Answer:

a). Genes are nothing but the segements of DNA. The gene expression is a process by which information from a gene is used in the synthesis of a functional gene product, protein.

b). Transcription occurs in the nucleus. It synthesizes mRNA from DNA template.

Translation occurs in the cytoplasm. It produces proteins according to the sequence of the mRNA

c). Transcription: Synthesis of mRNA from DNA template strand is called transcription.

Translation: Synthesis of protein according to the sequence of mRNA.

d).The mRNA is called as Messenger RNA. It brings the information from DNA to the ribosome, where they specify the amino acid sequence of the protein products of gene expression.
