Answer:

3' TGACTGTAC 5'

The two strands of DNA that make up the double helix with corresponding positions on the two chains being composed of a pair of complementary bases are known as complementary strands.

Adenine always pairs with Thymine. Cytosine always pairs with Guanine.

In mRNA, the thymine is replaced by Uracil. Adenine pairs with Uracil for mRNA formation.

Over [174]

Answer:

2. 1 Pink : 1 white

3. 1 Red : 1 Pink

4. 1 Red : 2 Pink : 1 White

Explanation:

This question involves a single gene coding for flower colour in snapdragon plants. The alleles of the gene exhibits incomplete dominance i.e. the red allele (R) ia not completely dominant over the white allele (W), hence an intermediate pink phenotype (RW) is formed. Based on this, a red snapdragon will have genotype, CRCR while a white one will have genotype, CWCW. The intermediate pink phenotype will have a genotype, CRCW.

The image attached to this question shows four crosses between different traits.

In the second cross between a pink (CRCW) and white offspring (CWCW), 2pink and 2white offsprings will be possibly produced in the ratio 1:1.

In the third cross between a red (CRCR) and pink (CRCW) snapdragon, 2 red and 2 Pink offsprings will possibly be produced in a ratio 1:1.

In the fourth cross between a pink (CRCW) and pink (CRCW) snapdragon, red, pink and white offsprings will be produced in the ratio 1:2:1.

See attached image for the complete punnet square. Note that, there was a mistake in the Genotype of the last cross i.e. pink has genotype CRCW not CWCW.

A change in direction without a change in speed is called velocity

Velocity can vary as long there is specific direction (displacement)

Speed has no direction therefore change in speed is not necessary the velocity...

Velocity is also in a specified direction

A dog called the Maltese doesn't shed. This type of dog most likely came about through _____. hybridization genetic engineering
katrin2010 [14]

Answer:

The correct answer would be hybridization.

Hybridization refers to the process by which organisms of different breed, species, or varieties are selectively interbred in order to produce offspring with desired characters.

Similarly, Maltese dogs were selectively bred in order to attain characters like the small size, less shedding of hairs et cetera.
