Which of the following curves correctly represents the process of ethanol production yeast?

Inbreeding for 5 generations led to the production of homozygous transgenic mice. However, these homozygous males or females were infertile. Which of the following approach is most preferable and economical to obtain heterozygous transgenic animals continuously?

• Moretransgenic founder (1^st animal) should be generated.

• Crossing (breeding) of transgenic mice with wild type mice in earlier generations should be done for the continued production of transgenic heterozygous offspring.

• Inbreeding should be avoided after 5^th generation.

• Homozygous transgenic mice should be mated with wild type for continued production of transgenic heterozygous offspring.

Electrons are transferred from reduced co-enzymes like NADH, NADPH to pyruvic acid or its derivatives during fermentation. Thos final electrons acceptors are reduced to the end-products for example lactic acid, propionic acid, etc. The end products depend on the particular microorganism and the substrate

Organism	End product
A. Streptococcus	a. Butanediol, formic acid
B. Clostridium	b. Lactic acid
C. Salmonella	c. Butyric acid, isopropanol
D. Enterobacter	d. Succinic acid, acetic acid

The correct match is

• A - a; B - b; C - c; D - d

• A - d; B - c; C - a; D - c

• A - b; B - c; C - d; D - a

• A - c; B - d; C - a; D - b
