SG 4.4

Question 1

Using the codon table to translate mRNA into amino acid sequence

Answer 1

using the tRNAs as adaptors to add each amino acid in the correct sequence to the end of the growing polypeptide chain.

Question 2

mRNA-
tRNA-
rRNA-

Answer 2

Positive regulation is that regulation in which the presence of specific regulatory element increases the expression of genetic information quantitatively.
Negative regulation is regulation in which the presence of specific regulatory elements diminishes the expression of genetic information.

Question 3

Gene Regulation- positive/negative transcription factors

Answer 3

Positive regulation is that regulation in which the presence of specific regulatory element increases the expression of genetic information quantitatively. Negative regulation is regulation in which the presence of specific regulatory elements diminishes the expression of genetic information.
