Dad: TtBb

Mom: ttbb

You have to use distribution for dihybrid crosses.  Meaning, the first allele of each trait has a equal chance of being paired with the other allele of the other trait.  So for example with Dad, I will number the traits:

T(1)t(2)B(3)b(4)

To set up the possibilities from Dad, it would be 13, 14, 23, 24: TB, Tb, tB, tb.  Same idea goes for Mom, except since all alleles are the same, you only need to make one column for Mom, since if you did all 4, the other 3 would just be repeats of the 1.

Cross:

                 tb

TB           TtBb

Tb           Ttbb

tB            ttBb

tb            ttbb

The phenotypic ratio is 1 Tall Brown: 1 Tall Blue: 1 Short Brown: 1 Short Blue

Dahasolnce [82]

Answer: A.) The nitrogen cycle recycles nitrogen through an ecosystem, making it available to all organisms.

Explanation: Nitrogen is an essential nutrient for plants and a significant component of proteins, which all animals need to grow, reproduce and survive. The nitrogen cycle converts nitrogen into compounds that plants and animals can use.

DNA replication is the process of doubling a DNA double chain. In cells, DNA replication occurs before cell division. Prokaryotes continually replicate DNA. In eukaryotes, the timing of DNA replication is highly regulated, ie in the S phase of the cell cycle, before mitosis or meiosis I. The multiplication utilizes the DNA polymerase enzyme which helps form bonds between the nucleotides that make up the DNA polymer. The process of DNA replication can also be carried out in vitro in a process called a polymerase chain reaction (PCR).

<h2>Further Explanation </h2>

A slow strand (Lagging strand) is a DNA strand located on the opposite side of the leading strand on the replication fork. These strands are synthesized in segments called Okazaki fragments. In this string, primases form RNA primers. The DNA polymerase can thus use OH 3 'free groups in the RNA primer to synthesize DNA in the direction of 5' → 3 '. The primary RNA fragments are then removed (for example by RNase H and DNA Polymerase I) and new deoxyribonucleotides are added to fill the gaps that were previously occupied by RNA. DNA ligase then connects the Okazaki fragments so that the synthesis of lagging strands is complete.

Primers both on the steering strand and on the lagging strand will elongate with the help of Holoenzyme DNA polymerase III. This multisubunit complex is a dimer, half will work on the steering strand and the other half will work on lagging strands. Thus, the synthesis of the two strands will run at the same speed.

Each dimer part of the two strands consists of subunit a, which has the actual polymerase function, and subunit e, which has an editing function in the form of exonuclease 3'– 5 ’. In addition, there is a subunit b that attaches polymerase to DNA.

Once the primers in the remaining strand are removed by DNA polymerase III, they will be removed immediately and the gaps caused by the loss of the primer are filled with DNA polymerase I, which has 5 '- 3' polymerase activity, 5 '- 3' exonuclease, and editing 3 exonuclease '- 5'. Eksonuklease 5 '- 3' discard the primer, while the polymerase will fill the gap caused. Finally, the Okazaki fragments will be united by the DNA ligase enzyme. In vivo, the dimoenzyme DNA polymerase III and primosomes are believed to form large complexes called replisomes. With the replisom DNA synthesis will take place at 900 bp per second.
