Answer:

Heterozygous means that the father has one dominant gene for tongue-rolling, and one recessive gene for non-tongue-rolling. The mother is homozygous recessive, meaning she has two copies of the non-tongue-rolling gene. This means that every child is guaranteed a non-rolling gene from their mother, and they have a 50% chance of inheriting a rolling gene from their father. Since the rolling gene is dominant, only one copy of the gene is required to show the trait, so the 50% of children with the rolling gene from their father will be able to roll their tongues. The answer is 50% of offspring.

100 percent

Explanation:

If you cross rr and RR you get four offspring with the trait Rr. Since there is one capital letter, they will all exhibit the dominant trait. Hope this helped!

Each of the proteins involved in DNA replication plays an important role. If one of these proteins was not functional it would h

Masteriza [31]

Answer:

Explanation:

1. Topoisomerase is an enzyme helps in over winding Or underwinding of DNA during replication. Helps in the topological correction. So non-functional topoisomerase leads to tangled DNA and prevents replication..

2. Primases are the enzymes helps in the synthesis of short RNA sequences used as primers in replication. Non functional primase leads to no primer synthesis.

3. DNA Polymerase is an enzyme helps in the addition of new nucleotide to the growing strand in replication. Non functional DNA polymerase prevents the strand growing as no new nucleotides were added.

4. Helicases are the enzymes helps in the separation of double strands into single and helps in each strand to be copied. Non functional helicase leads to prevention of unwinding of strands and replication inhibition.

5. ligase is an enzyme that joins nicks(small gaps) in the DNA strand by creating ester bond. Non functional ligase leads to unjointed gaps of lagging strand.

6. Single strand binding proteins(SSB's) are the small proteins that binds to the single strands of DNA and holds them in a place not to get together while replicating. Non functional SSB's leads to parental strands come back together and prevents replication.

Helium nuclei are more difficult to fuse than hydrogen nuclei because they have a greater positive charge.

nataly862011 [7]

<span>Helium nuclei have a positive charge of 2+ when observed. Compared to a hydrogen nuclei, we can see that the Helium nuclei is more difficult to fuse as it has a greater charge than Hydrogen 1+. This chemical difference makes the answer true.</span>
