The term for monohybrid cross parents (or pure breds) is Homozygous. :)
Answer:
The correct option is B
Explanation:
The alpha and beta-gamma subunits both can bind to target proteins. Once a G protein becomes active, its alpha subunit and beta-gamma dimer both have the ability to pass on messages in the cell via connecting or binding with other membrane proteins that are involved in the transduction of signals. In this light, B is the best option.
The answer is:C
Explaination
Answer:
Explanation:
Being able to identify minerals is important, because mineral identification is necessary to identify rocks and can be used to understand both the landscape and the geologic history of the area.
Attachment of acetyl groups to histone promotes transcription.
This mechanism is known as histone acetylation and it is a part of gene expression. The lysine residues inside the N-terminal tail from the histone core of the nucleosome are the substrate for enzymes-histone acetyltransferase which transfer an acetyl functional group from another molecule. Acetylation removes the positive charge on the histones and thus decrease the interaction negatively charged phosphate groups of DNA. As a result, chromatin becomes more relaxed structure and transcription is promoted.
