Different genes are activated in the blood cell than in the liver cell.
Explanation:
All the cells in the body contain the same number of genes and genetic material DNA but not all genes are expressed in a single cell.
The highly regulated process of the genes in molecular biology promotes the expression of particular gene required.
Signals from the cell environment activate the transcription factor that binds to regulatory regions of the gene, hence transcribing and making proteins for the same.
The genes for both blood cell and the liver are different but will be present in all the somatic cells, the regulatory mechanism will choose the required gene to be transcribed.
Answer:
D
Explanation:
1. As given, the overall genome contain 50% G+C.
And the concept is that G is always pairs with C.
and A is always pairs with T.
So, in a dsDNA, A+G= T+C
2. As there that, there is a cluster of genes comprising about 20,000 bp that is 64% G + C so this so that the 20,000 bp segment is a recent acquisition via horizontal gene transfer.
Answer:
Asteroids are rocky worlds revolving around the sun that are too small to be called planets. They are also known as planetoids or minor planets. There are millions of asteroids, ranging in size from hundreds of miles to several feet across.
Option 2 is the correct answer because two bases will be equal in quantity
The answer is jointed legs.
Arthropods has another smaller classification, which includes insects, arachnids, crustaceans and myriapods. Some of their common characteristics includes segmented body, jointed legs etc.
Others like hard shells or gills are only present in certain types of Arthropods, which in this case is crustaceans.
Meanwhile Arthropods has exoskeleton, instead of endoskeleton. It's like a hard shell outside of their body, to protect them.
