The answer is B) Genetic variation
A bunch of the same critters. Nah I am just kidding, you will find a lack of resources because if they are all the same animals they will all eat the same thing. I hope this helps you.
Answer:
A = Activator
B = Effector
Explanation:
An activator is a protein which typically binds to a short (50–1500 bp) region of DNA which might be located either upstream (mainly) or downstream of a gene so as to cause increased transcription. This particular region of DNA is known as enhancer and activator is also known as transcription factor. Activator is a trans-acting factor which binds to the cis-acting factor which is enhancer so as to enhance transcriptional expression.
But another protein named as effector may restrict activator from binding to the enhancer leading to a decrease in transcriptional expression by binding to the activator allosterically. Allosteric binding of effector to the activator causes conformational change in activator so it can no longer bind the enhancer.
<h2>Answer:</h2>
The correct statement is option A which is, "A gene is a segment on the DNA. DNA is wrapped in proteins to form a chromosome".
<h3>Explanation:</h3>
- A gene is the part of DNA in the nucleus which encodes for the specific trait in the body. DNA is the nucleotide sequence which is the blue print for the whole organism. It contains genes for all the structures and functions in the body.
- So it is very long sequence containing the million of genes. So in nucleus it is present in compress form. It is wrapped on the histones proteins and condense and supersondense into a specific structure which is known as chromosome.
