Answer:

b. Elongation

Explanation:

During the start of the elongation phase of RNA synthesis, the sigma subunit of RNA polymerase of E. coli is released and NusA protein takes its place. This makes the RNA polymerase to move away from the promoter.

During the elongation phase of RNA synthesis, the enzyme DNA dependent RNA polymerase elongates the RNA strand by addition of ribonucleotides to the free 3'-OH end. The process occurs in 5' to 3' direction and the 3'-OH group serves as a nucleophile.

Assuming a typical monohybrid cross in which one allele is completely dominant to the other, what phenotypic ratio is expected i

IgorC [24]

Answer:

Assuming the dominant allele is represented as A, and the genotype as AA and the recessive as a, and genotype as aa; then the F1 will produce the offispring. Aa, Aa, Aa,Aa in ratio: 1:1:1:1:1

This shows the dominance of allele A.

However if two of the F1 generation are crossed then:

The F2 is AA,Aa,Aa,aa the phenotypic ratio is

3 ; 1

While the Genotypic ratio is ratio;

1AA : 2Aa Aa; 1aa(1 ;2;1)
