In this project, you will analyze claims about the causes of inherited genetic variation. You will then make your own claim base

d on prior knowledge. Next, you will defend your claim by conducting research to
gather information that supports it. Finally, you will present your claim and defense in a typewritten paper. Anyone did this?

Answer:

Explanation:

In the 21st century, biotechnology has developed rapidly, and the era of great health has arrived. Cell therapy has opened up new ideas for the treatment of refractory diseases in human beings and has broad application prospects. Cell biology, molecular biology, and modern immunology are the three leading modern biological sciences. Cell therapy utilizes the characteristics of certain cells with specific functions. After bioengineering or in vitro amplification and special culture treatment, these cells have therapeutic effects such as enhancing immunity, killing pathogens and tumor cells, and promoting tissue regeneration, so as to achieve the purpose of treating diseases. Techniques such as cell culture proliferation and differentiation are among the most commonly used methods in cell biology research. Since the basic laws of cell behavior are the same in vitro culture and in vivo, many studies can be performed in vitro. More importantly, people can selectively and purposefully control the environment in which cells grow, so they can study the biological behavior of cells under certain special conditions.

Assay Development Service

Genetic/epigenetic analysis service

Epigenetics refers to the regulation of epigenetic gene expression by epigenetic changes (DNA methylation, histone modifications, and non-coding RNAs such as miRNAs) that are independent of genetic sequence changes and can be genetically apparent. DNA methylation, histone modifications, and miRNAs are a reflection of changes in environmental stimuli that interact to regulate gene expression and control cellular phenotype. Massively parallel sequencing technology lays the foundation for the construction of epigenomics. Creative Biolabs provides key sequencing-based methods used in the analysis of epigenomes, including bisulfite sequencing, chromatin immunoprecipitation sequencing, 3D chromatin capture, as well as the determination of open chromatin.

In vitro assay development service

In vitro or phenotypic assays are defined as those that model some aspect of disease biology in cells or tissues derived from an experimental species or humans, which have important clinical implications for disease progression and treatment. In vitro assays have the following benefits: obtaining direct knowledge related to the potential new disease background; multiple compounds with different modes of action can be tested, and depending on the throughput of the assay, within a certain range; it provides data support for more complex phenotypes or subsequent assessments or in vivo trials. The examples given in the various disease areas use a wide range of cell-based assay types, typically in 96-well formats, which differ markedly in their outcome when compared to, for example, biochemical or in vivo assays.

Assay Development Service

In vivo assay development service

The experimental animals themselves are studied for their breeding, biological characteristics and information, new varieties cultivation and disease diagnosis, treatment, and prevention to achieve people's purposes. Taking animals as a model, some experiments are carried out in vivo to study the reactions, manifestations and developmental rules of animals, and lay the foundation for solving complex diseases of human beings. The services of in vivo assay include assessing the phenotypic characteristics of transgenic lines, functional MRI services for awakening animals to visualize neural networks, and assessing transporter activity and building animal models, etc.

Please explain the difference between a frameshift mutation and a base substitution mutation.
harina [27]

Answer:

A frameshift changes every codon past it. A base substitution only changes one codon.

Explanation:

DNA is comprised of nucleotides (A, C, T, G) that make up amino acids. Every three bases is called a codon and represents an amino acid.

In a frameshift mutation, a nucleotide is either added or deleted from the sequence. This offsets the entire sequence after it because the reading frame shifts. Here's an example:

ACTGCTATCGTCATC

If another T is added in between the first and second codons, then every codon after will be changed.

ACT>T<GCTATCGTCATC

A substitution mutation is usually less severe, as it only alters one codon in the sequence. These occur when one nucleotide is replaced by another one. Here's an example:

ACTGCTATCGTCATC

Let's say the first G is replaced by a T.

ACT>T<CTATCGTCATC

As you can see, none of the other codons changed.

Typically, a frameshift mutation is considered worse than a substitution mutation.

A plant with green leaves &amp; red flowers is placed in a) Green ; b) red ; c) Blue light. What color will the leaves &amp; flo
nikitadnepr [17]
<span>a).only leaves will show color flower will tend to be dark. b).only flower will show up leaves will tend to be dark. c). both leaves and flowers will be dark. (any object which has a color absorbs rest of colors of spectrum except that color which it reflects for example: green leaves absorbed v.i.b.y.o.r. except green which is reflected by leaves) so if placed in red light they will not show any color because leaves will absorb red color)</span>

The pluripotent, undifferentiated cells in the bone marrow that give rise to the formed elements are called _____ cells
LuckyWell [14K]

The pluripotent, undifferentiated cells in the bone marrow that give rise to the formed elements are called stem cells.

Pluripotent stem cells have the ability to undergo self-renewal and to give rise to all cells of the tissues of the body. However, this definition has been recently complicated by the existence of distinct cellular states that display these features.

There are two types of pluripotent stem cells :

  • Embryonic stem cells (ESCs)
  • Induced pluripotent stem cells

Embryonic stem cells are derived from the inner cell mass (ICM) of pre-implantation embryos and can be indefinitely maintained and expanded in the pluripotent state in vitro. Pluripotent stem cells can also be obtained by inducing dedifferentiation of adult somatic cells through a recently developed in vitro technology, known as cell reprogramming.

Similarly to  Embryonic stem cells , Induced pluripotent stem cells can be expanded indefinitely and they are capable to differentiate in all the derivatives of the three germ layers.

Another intriguing features of being pluripotent is its reliance on gene expression heterogeneity.
