Answer:

Let's consider that the allele 'B' is for Black hair colour and it is dominant. Let's consider that the allele for red hair colour is b.

Let's consider the allele for lacking horns or polles is 'P' and it is dominant. The allele for having horns is 'p' and it is recessive.

When two heterozygous black, lacking horns (BbPp) are crossed, the results will have the probability of 9 black/polled : 3 black/horned : 3 red/polled : 1 red/horned organisms.

Answer:

Bacterial genomes contain small transposable elements termed <u>Jumping Genes</u> that resemble transposons of eukaryotic cells.

Explanation:

Jumping genes are small parts of the DNA that program enzymes and move it from one DNA location to another, sometimes on the same molecule of DNA sometimes on another molecule.

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3' Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3' The two primers above have the melting

CaHeK987 [17]

Answer:

Short answer is primers are partially complementary.

Explanation:

Forward primer: 5'-AGTCTACTCGTAACCGGTTACC-3'

Reverse primer: 5'-TAAGGCATCATGGTAACCGGTT-3'

When we write reverse primer 5' to 3' we can easily see that

3'-TTGGCCAATGG---5' is complementary to the forward primers'

5'---AACCGGTTACC-3' sequence. So instead of binding to the template DNA these primers might bind each other resulting with reduction of efficiency of DNA amplification.
