Answer:
C. 1/4
Explanation:
Let's assume that the allele for the spotted coat is "S" and the one for the even coat is "s". The allele "L" gives short horns while the recessive allele "l" imparts long horns. The genotype of the cattle heterozygous for both traits would be SsLl. A cross between two heterozygous cattle would produce progeny in following phenotype ratio=
9 spotted coat and short horns: 3 even coat and short horns: 3 spotted coat and long horns: 1 even coat and long horns.
Therefore, the proportion of the progeny with long horns = 4/16= 1/4
Answer:
What contains genes that are the instructions for making proteins
Explanation:
The DNA code contains instructions needed to make the proteins and molecules essential for our growth, development and health. DNA? provides instructions for making proteins
Answer:
The correct matching pairs are:
1) - B)
2)- E)
3) - A)
4) - F)
Explanation:
<u>Transferases (B)</u>: Transeferases is the class of enzyme that catalyzes reactions involving the <u>transfer of certain functional groups. (1)</u>
Example: Transaminase transfers nitrogenous groups
<u>Isomerases (E)</u>: Isomerases is the class of enzyme that catalyzes <u>isomerization reactions and intramolecular rearrangements. (2)</u>
Example: Triosephosphate isomerase interconverts aldoses and ketoses
<u>Oxidoreductases (A)</u>: Oxidoreductases is a class of enzyme that catalyzes <u>redox reactions (3) </u>which involves the simultaneous transfer of electron.
Example: Alcohol oxidoreductases acts on the alcohol functional group
<u>Ligases (F)</u>: Ligases is a class of enzyme that catalyzes reactions involving <u>chemical bond formation between two molecules. (4)</u>
Example: DNA ligase joins DNA fragments

A major problem in sending space probes to Jupiter is that the planet has no solid surface on which to land, as there is a smooth transition between the planet's atmosphere and its fluid interior. Any probes descending into the atmosphere are eventually crushed by the immense pressures within Jupiter
