Both men and women conceived during the widespread famine of the Dutch Hunger Winter were more likely to be obese by age 5050 an

d more likely to die from stroke or cardiovascular disease. They also experienced more cognitive decline later in life. Fifteen genetic loci associated with growth and metabolic disease were compared between siblings prenatally exposed to the famine and those siblings who were not prenatally exposed.
1. What evidence suggests that these are epigenetic effects?

a. missense mutations within genes encoding histone proteins
b. single nucleotide polymorphisms within loci involved in growth and metabolic disease
c. transposon insertion into loci involved in growth and metabolic disease
d. changes in the methylation patterns of loci involved in growth and metabolic disease

2. Which additional pieces of evidence would help to demonstrate that these effects are due to epigenetic changes?

a. changes in the post-translational modification of metabolic enzymes
b. differences in the expression of metabolic genes
c. mutations in the DNA regions associated with cardiovascular health
d. changes in histone acetylation patterns

Answer:

1. d. changes in the methylation patterns of <em>loci</em> involved in growth and metabolic disease

2. b. differences in the expression of metabolic genes

d. changes in histone acetylation patterns

Explanation:

Epigenetics refers to the study of heritable changes in gene expression which are not dependent on DNA sequence. Epigenetic mechanisms involve DNA methylation, histone modifications (acetylation, methylation, phosphorylation, etc) and regulatory non-coding RNA (ncRNA) pathways. These epigenetic mechanisms work together and mutually reinforce each other in order to modulate gene expression (either by activating or suppressing gene expression). In consequence, transcriptome data (e.g., genes differentially expressed in particular tissues/cells or stages of development) is an important piece of evidence indicating the existence of epigenetic modulation.

What influences other than humans affect genetic drift in populations?
Lelu [443]

Answer:

Every population experiences genetic drift, but small populations feel its effects more strongly. Genetic drift does not take into account an allele's adaptive value to a population, and it may result in loss of a beneficial allele or fixation (rise to 100% frequency) of a harmful allele in a population.

How many alleles does a baby guinea pig inherit from the mother?
Harman [31]
The amount of alleles that a baby Guinea pig inherit from the mother are two , 1 from its mother and 1 from its father ( The very reason why we use them as an experiment tester is because this similarities)
For Example, if its mother hat a dominant black fur (BB) and its father has recessive grey fur (bb)  , there is 100% chance that the baby will has a Bb genotype, which will give them either black fur or dark grey fur.

Which laundry detergent removes stains more effectively?
TEA [102]

Enzyme-containing laundry detergents will remove stains more effectively than detergents without enzymes. Stains will be removed more successfully from clothing with homemade laundry detergent than from commercial detergents.

A variable that is independent is precisely what it sounds like. It is a stand-alone variable that is unaffected by the other variables you are attempting to assess. Age, for instance, could be an independent variable. A person's age won't alter as a result of other circumstances like what they eat, how much they attend school, or how much television they watch. In actuality, when attempting to establish a link between two variables, you are attempting to determine whether the independent variable affects the dependent variables in any way.

A dependent variable is precisely what it sounds like, just like an independent variable. It is something on which other elements depend. A test score, for instance, maybe a dependent variable because it could vary based on a number of variables, including how much you studied, how much sleep you got the night before the test, and even how hungry you were.

What is a group of cells working together called?
anyanavicka [17]
Salutations!

A group of cells working together are called tissues. Organisms are made up of this structure. Cells are the smallest unit of life. A group of tissues working together is called organ. A group of organs working together is called organ system. An organ system working together makes up an organism.

Hope I helped (:

Have a great day!
