How does heredity affect a species

1 answer:

6 0

Heredity, the sum of all biological processes by which particular characteristics are transmitted from parents to their offspring. The concept of heredity encompasses two seemingly paradoxical observations about organisms: the constancy of a species from generation to generation and the variation among individuals within a species. Constancy and variation are actually two sides of the same coin, as becomes clear in the study of genetics. Both aspects of heredity can be explained by genes, the functional units of heritable material that are found within all living cells. Every member of a species has a set of genes specific to that species. It is this set of genes that provides the constancy of the species. Among individuals within a species, however, variations can occur in the form each genetics, providing the genetic basis for the fact that no two individuals (except identical twins) have exactly the same traits.

Start with the temperature at 25 ºC and the pH at 7. Do not vary these parameters while testing for substrate (Initial Lactose)

UNO [17]

Answer:

The results show that the increase in the substrate concentration is increasing the rate of the reaction. We can see that the reaction rate has increased to 2.88mM/min. After this even if we increase the substrate concentration

Epigenetics may be defined as changes in the expression of a gene or set of genes by _______ and _______.

nataly862011 [7]

Epigenetics is the study of how DNA methylation and alterations to chromosomal proteins affect a gene or group of genes express themselves. For changes in a gene's expression, both of these are need.

In a biological process called DNA methylation, methyl groups are added to the DNA molecule. A DNA segment's activity can be altered by methylation without the sequence changing. DNA methylation usually inhibits transcription of genes when it occurs in a gene promoter.

Epigenetics literally translates to "along with changes in genetic sequence." Any procedure that modifies gene activity without altering DNA sequence and results in modifications that can be passed on to daughter cells is now included in the term. Is called Epigenetics.
