Answer: When genes found on different chromosomes, said to be not linked.
When genes seen close together on the same chromosomes said to be linked.
Explanation:
(a)
According to Mendel’s law of independent assortment, when genes located more than 50 map units and found on different chromosomes as far apart on the same chromosome so they divide independently and obviously said as not linked.
(b)
It is found that when genes located and seen tightly close together on the same chromosome, known to called as Linked which means that alleles or genes look close together on the same chromosome can be inherited afterwards as a unit frequently than not. For instance, when two genes are linked and become tightly close together by using data from genetic crosses lead to calculate recombination frequency as well.
Similarly, when we finding recombination frequencies for more than one gene pairs, can make linkage maps among them that finally show the relative distance between them.
I think it is Free Radical.
The Trex-Binding Factor in Muscle Creatine Kinase Enhancer has been identified and described below.
The Muscle Creatine Kinase Enhancer contains a positive control site called Transcriptional Regulatory Element X (Trex). The Trex site is critical for MCK expression in skeletal and cardiac muscle, according to research using transgenic animals and cell culture. Quantitative proteomics was used to identify the Trex-binding factor (TrexBF) as Six
a homeodomain transcription factor of the Six/sine oculi's family, from a background of about
copurifying proteins, following selective enrichment for TrexBF using magnetic beads coupled to oligonucleotides containing either wild-type or mutant Trex sites. We showed that Six4 is TrexBF in mouse skeletal myocytes and embryonic day 10 chick skeletal and cardiac muscle, but Six
is the primary TrexBF in adult mouse heart, using gel shift assays and Six-specific antisera. Six
transactivates in co transfection investigations.

An antigen triggers a response from the immune system and an antibody is produced. All antibodies are immunoglobulins, therefore, the correct answer is immunoglobulin. More specifically, an immunoglobulin is a protein produced by plasma cells to fight and neutralize pathogens. To do so, the immunoglobulin has a specific region which is complementary to a specific region of the antigen. Immunoglobulin's mechanism of action is to bind to the pathogen and either block its action or trigger a response of other cells of the immune system.
