<h2>
Meselson and Stahl conducted an experiment to determine the correct proposed methods of DNA replication was semi-conservative
. the three proposed models for DNA replication are semi-conservative, conservative, and dispersive.</h2>
Explanation:
In Semi-conservative replication model, the two strands of DNA uncoil from each other. It perform with the original strand and a new strand.
In Conservative replication model, DNA replication didn't open at all, but the parent strands remains undamaged by creating a new and separate molecule that consists of two new strands.
In Dispersive replication model, DNA replication results in two DNA molecules that consists of both parental and daughter DNA.
He demonstrated that semi-conservative DNA replication is an universal mechanism allocated by all organisms on Earth.

<h3>IVF: Is the process painful?</h3>
It is comparable to a pap smear or even a vaginal ultrasound appointment. During this technique, an embryo transfer catheter and ultrasound guidance are used to transfer one or more embryos to the uterus. The entire operation will be visible to you on an ultrasound screen. This procedure is painless.
<h3>What distinguishes IVF from in vitro fertilization?</h3>
An IVF procedure involves surgically removing a woman's eggs from her ovaries and fertilizing them in a lab with sperm from a male partner or a sperm donor to produce embryos. (The term "in vitro" refers to the act of fertilizing an egg in a laboratory dish and is derived from the Latin meaning "in glass").

Answer:
Although an individual gene may code for a specific physical trait, that gene can exist in different forms, or alleles. ... In other cases, each parent provides a different allele of a given gene, and the offspring is referred to as heterozygous ("hetero" meaning "different") for that allele.
<u><em>My answer is that this statement is false.</em></u>
