<span>In vitro fertilization
Not much to say, the question pretty much defines the technique. The first successful birth via IVF happened with the birth of Louise Brown in 1978. There are some issues with IVF that can cause complications. Among them are multiple births (twins or triplets) due to multiple blastocysts successfully implanting in the woman's uterus.</span>
Answer:
The answer is aabb (Cremello).
True ..In animals, the female mitotic sequence produces only one ovum; the other three haploid cells become "polar bodies".
Answer:
a. Ligase
b. Ligase (
it's repeated)
Explanation:
DNA synthesis begins, therefore, by synthesizing a short segment of RNA called a primer, which primer is synthesized by an enzyme called Primasa. Primasa is an RNA polymerase that uses DNA as a template. All fragments of Okazaki begin with a Primer. Subsequently, the DNA polymerase III Holoenzyme performs the synthesis of the corresponding DNA fragment until it reaches the next primer. At that time, DNA polymerase Ia replaces the DNA polymerase Holoenzyme III. The DNA polymerase I is responsible for removing the RNA primer through its 5'P-3'OH exonueotic activity and at the same time fills the hole by synthesizing DNA.
Finally, the two Okazaki fragments have to be joined, it is necessary to link the 3'OH end of a fragment with the 5'P of the next fragment. This work of sealing and joining the successive fragments is done by Ligase.
