of bases are in each chromosome?
Answers
Explanation:
The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells.

What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

On the colorful map, in general, where is the youngest crust located?
Answers
Answer:
The youngest crust (shown in red) is near mid ocean ridges and spreading zones. All three rock types in the earth's crust—igneous, sedimentary, and metamorphic—can also be recycled back to their original molten magma form. This process occurs when oceanic crust is pushed back into the mantle at subduction zones.

Answers
Answer:
allele-specific oligonucleotides (ASOs)
Explanation:
An allele-specific oligonucleotide (ASO) is a piece of synthetic DNA that is short and usually a complementary to the sequence of a target DNA, It is an oligonucleotide of 15–21 nucleotide bases in length.
It acts as a probe in southern blot assay or simpler Dot blot assay to identify the presence of a target.
It is an important research tool in genetic testing, forensics, and Molecular Biology.
The probes can detect a difference of as little as 1 base in the sequence targeted.

Leaves of a healthy potted plant were coated with Vaseline to block stomata. Will this plant remain healthy for long? State three reasons for your answer.
Answers
➜ If waxy coating is made on the surface of leaf, loss of water in the form of water vapour does not take place. Even the gaseous exchange will not take place. So, photosynthesis will either be reduced or will not take place.
The plant will not remain healthy for long because:
[i] Exchange of gases will not take place.
[ii] Photosynthesis will either be reduced or will not take place due to lack of CO2.
[iii] Transpiration will not take place, so there will be no mechanism of cooling in hot weather.
