Answer: Autosomal recessive

Explanation:

Autosomal recessive is the genotypic type of expression of traits. In an autosomal recessive disorder, 2 copies of an abnormal gene must be present which are responsible for the development of the trait.

The parents of the individual that have an autosomal recessive each must carry a copy of a mutated gene or deffected or abnormal gene but they do not show signs and symptoms of the condition. The autosomal recessive disorders are not seen in every generation of the family which is affected.

Why colonial organisms that lived grouped together
Luba_88 [7]

Answer: Colonial organisms are the result of many identical individuals joining together to form a colony. These cells are partly dependent on each other to start with. But, later evolutionary events resulted in the obligatory relationships among them resulted in multicellularity.

Place the primers in the correct orientation and locations to amply this gene by pcr. if a primer does not belong in a particula

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.

What characteristics do mutations have ?
aliya0001 [1]
Some genetic mutations can be completely harmless, while others are life-altering. Mutations happen when DNA is copied incorrectly. This causes an irregularity in the DNA. Mutations are permanent changes to genetic material that can be passed on to offspring. These changes happen randomly and can occur in any type of gene. While some mutations are not harmful (hazel eyes, for example), many mutations have harmful effects on health.
