Histones copy the DNA before division begins is the correct role of histones.

A chromosome's structural support is provided by a protein called a histone. Long DNA molecules found on each chromosome must fit into the cell nucleus.

To do it, the DNA wraps around complexes of histone proteins, giving the chromosome a more compact form. Additionally, histones are involved in the control of gene expression.

A nucleosome, which is made up of eight histone proteins, can exist. DNA can loop around a nucleosome much like a small spool. Thus, histones are crucial in maintaining the genome's order and neat wrapping inside a cell.

Therefore, Histones copy the DNA before division begins is the correct role of histones.

Answer:

The correct answer would be - GG and gg.

Explanation:

As it is given that all the 1000 offspring having the same allele Gg which is only possible in one condition that is cross between GG and gg because it is a heterozygous condition in the offspring. So there must be both allele present and it can not be heterozygous parents as there would be a different combinations of offspring in that case.

If the parents either GG only all the offspring would be GG the same with gg than all the offspring will be gg, thus the correct answer would be GG and gg.

Answer:

Without the ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

Explanation:

A species' ecological niche can be defined as the range of resources and conditions allowing the species to maintain a viable population a more simple definition is if two species have the same niche, one species will exclude the other.

Answer:

The correct answer is B.

Explanation:

DNA was discovered in 1800, and then scientists studied DNA with X-Rays. After a while, scientists published a 3D model of DNA, and shortly after, scientists decoded DNA genes. So the answer is Option B.

Hopefully, this helps! :D

Ask your question below!

In the 1800s first the discovery of DNA was done, than the X-ray study of the DNA was done, after that the 3-D model of the DNA was developed, and finally human genetic code was decoded in the 1960s.  

• The DNA was initially identified in the late 1860s by Friedrich Meischer, a Swiss chemist.  

• After that Rosalind Franklin and Wilkins studied DNA with the help of X-ray diffraction tool.  

• In the 1953s, the 3D model of the DNA molecule was discovered by Watson and Crick.  

• Finally in the 1960s, Nirenberg and his colleagues at the National Institutes of Health deciphered the human genetic code.  

Thus, the second timeline shows the correct order of contributions made to the discovery of DNA.

Answer:

The correct option is Polar

Explanation:

The polar region/arctic are located/extend from 66.5 degrees N (north) and also S (south) latitude to the north and south poles of the earth. From this, it can be deduced that the polar region is located between 60-90 degrees of N and 60-90 degrees of S.  Polar regions are far from the equator as a result of this and are characterized by very low solar radiation.

Polar or artic region is located between the coordinates 60-90N and 60-90S. The polar regions are extremely far away from the equator, which is situated at 0-degrees latitude.

The correct answer is:

Option B. Polar

The polar region is defined as the region situated 60-degrees north or south of the equator. The solar radiation in the polar region ranges from only 18 hours and 5 hours during winters.

The middle latitudes are situated between 30N and 30S of the equator. It is characterized by moderate sunlight.

Tropics or tropical rainforests are situated near the equator and usually experience a warm climate.

Therefore, option B is correct.

Answer: I think these are the answers:

- Cancer can spread around the body.

- Cancer cells invade healthy tissue.

- Cancer cells display contact inhibition.

- Cancer comes in many forms.

- Cancer cells divide uncontrollably.

and I think "Cancer does not obey contact inhibition." is one too... I hope this helps! :D

Explanation:

Cancer cells:

• Divide uncontrollably

• Comes in many forms

• Invade healthy tissues

• Does not obey contact inhibition

Cancer is a diseased condition in which uncontrolled cell division takes place.

Cancer are of two main types: benign and malignant.

Benign tumours are localized to a particular organ and thus can be removed through chemotherapy or surgery.

Malignant tumours spread to body parts through blood stream and attack the healthy cells. This property of metastasis is unique to cancer cells.

Normal cells show their contact with the adjacent cells. In cancer, contact inhibition is lost and so they divide in an uncontrolled manner.

Breast cancer, leukaemia, lung cancer etc are some of the examples of cancer.

Cancer is detected through tissue biopsy. X-Rays, CT-Scan, MRI are some other techniques that detect cancer in the body.

Cancer can be treated if diagnosed early. Radiotherapy, chemotherapy and surgical intervention are the part of cancer treatment.

Therefore, cancer is considered a serious medical complication.
