Which of the following explain(s) how epigenetic inheritance occurs? Select all that apply. A.Histone modifying enzymes are capable of propagating histone modifications from nucleosome to adjacent nucleosome. B. Base modifications on a DNA strand assist with the modification of histones. C. Histone modifying proteins are capable of independently remembering the specific modifications that need to be added to newly synthesized DNA. D. Following replication, modified histones associate with unmodified histones.

Answers

Answer 1

Base modifications on a DNA strand help in the modification of histones, and histone-modifying enzymes are capable of spreading histone modifications from one nucleosome to an adjacent nucleosome. The selected statements are 1 and 2.

Histones are the main proteins that make up eukaryotic chromatin and are involved in the regulation of genes. They are extremely basic proteins rich in lysine and arginine residues that serve as the spools around which nucleosomes, which are structural units made of DNA wound around it.

Important chromatin structure and gene transcription are regulated by histone modifications, which have an impact on a number of significant cellular abnormalities. Thus, histone is considered the key regulator of epigenetic inheritance.

The new DNA strands are similarly changed by the histone-modified enzymes as the old DNA. Inheritance patterns can therefore be passed on to the next generation. Epigenetic inheritance thus happens.

Answers

Answer:

When chocolate melts, the molecules in the chocolate gain more freedom of movement. To correctly show this change in a model, you can add a layer of movement to the molecules, such as showing them vibrating or rotating. You can also show the molecules breaking apart and reforming into different shapes, as they gain more freedom of movement.

In contrast to heterotrophs, which cannot produce their own food and must rely on autotrophs for sustenance, autotrophs are creatures that create their own food through the process of photosynthesis.

Because they lack chlorophyll, some plants must get their nutrition from other plants. These plants are referred to as heterotrophic plants because they display a heterotrophic method of feeding.

In order to transfer, an F factor must have which of the following? a. oriV and its own DNA polymerase b. oriV and tra genes c. oriT and tra genes d. oriT and its own DNA polymerase e. oriT, tra genes, and its own DNA polymerase

Answers

In order to transfer, an F factor must have oriT and tra genes.

The origin of transfer (oriT) is the sequence at which conjugative transfer of plasmid DNA is initiated and is essential for cis of plasmid recruitment.

Transformer (tra) genes regulate all aspects of somatic differentiation in Drosophila melanogaster females and are non-functional in males. We isolated the tra gene as part of a 200 kb chromosome walk.

The tra operon of the F family of conjugative plasmids encodes most of the proteins involved in bacterial conjugation. This study shows that activation of tra operon transcription requires the cooperative binding of her two proteins, TraJ and ArcA, to flanking sites immediately upstream of the major tra promoter, PY.

how many codons would be needed to code for a protein that has 50 amino acids

Answers

A codon is a sequence of three nucleotides that codes for a specific amino acid. In order to code for a protein that has 50 amino acids, it would require 50 codons.

This is because each amino acid is coded for by a specific codon, and the sequence of codons determines the sequence of amino acids in a protein. Since there are 20 common amino acids used in proteins, and the genetic code is redundant, more than one codon can code for the same amino acid.

It's important to note that the genetic code is redundant, meaning that more than one codon can code for the same amino acid, this means that the total number of codons used to code for a protein with 50 amino acids may be greater than 50.

Answers

An egg with 22 chromosomes that is fertilized by a normal sperm will result in a zygote with normal chromosome number.

Typically, the male and female gametes (sperm and eggs) have 23 chromosomes apiece. However, occasionally an egg will be missing one chromosome because the chromosomes did not adhere to the spindle fibres appropriately during meiosis.

The egg would then only contain 22 chromosomes. A zygote produced from such an egg would have just 45 instead of the typical 46 chromosomes if fertilised by a normal sperm (containng 23 chromosomes). This ailment is known as monosomy.

Answers

Based on the genotypes provided, it is not possible to determine who the true Baby Daddy is.

Who is the true Baby Daddy?This is because the child would need to have the same genotype as one of the two possible fathers in order for it to be determined that one of them is the true father. Since the child has a blood type of A, and neither Daddy #1 or Daddy #2 have the same type, it cannot be determined which one is the true father.The process of determining the biological father of a child is known as paternity testing. To determine paternity, the child's blood type (A) and the mother's (B) must be known. Baby Daddy #1 has a blood type of O, while Baby Daddy #2 has a blood type of AB. From this information, we can deduce that Baby Daddy #2 is the true biological father.The mother's genotype must include both an A and a B gene, since the child's blood type is A. Baby Daddy #1's genotype must contain two O genes, as his blood type is O. Baby Daddy #2 is the only possible father, since his genotype must contain one A gene and one B gene in order for the child to have a blood type of A. By testing the blood types of the mother, the potential fathers, and the child, we can determine the true biological father. This process is known as paternity testing, and it is useful for determining the legal father of a child, as well as for providing medical information to parents and their children.

What is the temperatures about?

In Vancouver, the climate is characterized as a maritime climate which is mild with no dry seasons, the average temperature in winter is around 5-8C and in the summer is around 15-20C, the city is known for its rainy weather throughout the year.

On the other hand, Kamloops has a semi-arid climate, which is characterized by hot summers and cold winters. The average temperature in winter is around -5C and in the summer is around 25C, the city is known for its dry and sunny weather throughout the year.

Therefore, the difference in average temperatures in winter and summer is mainly due to the difference in the distance between the two cities and the coastal and inland location. The proximity of Kamloops to the interior of British Columbia results in a greater variation in temperature between the seasons due to the lack of a moderating influence from the ocean.

If you have inserted a gene in the Ti plasmid, the next step in genetic engineering is

Answers

The next step in genetic engineering after inserting a gene into the Ti plasmid is to transfer the plasmid to a host organism, confirm the stable integration of the plasmid, study the effects of the gene, and optimize gene expression before scaling up the production and purifying the protein of interest.

The next step in genetic engineering after inserting a gene into the Ti plasmid is to transfer the plasmid to a host organism.

This is typically done through a process called transformation, in which the plasmid is introduced into the host organism using various techniques such as electroporation, chemical transformation, or heat shock.

The host organism will then be able to express the new gene and produce a protein or other product encoded by the gene. Once the transformed host organism has been obtained it is necessary to confirm that the plasmid has been stably integrated into the host genome and the new gene is being expressed.

After that, the researcher would need to study the effects of the gene and its product on the host organism. Depending on the specific application, this may involve testing the host organism's growth, metabolic activity, or ability to resist disease.

The researcher may also want to optimize the expression of the new gene, this could involve optimizing the culture conditions, or using promoters or other genetic elements to increase the rate of gene expression. The final step is to scale up the production and purify the protein of interest.
