Answer:
Regulatory sites e.g enhancers and silencers
Explanation:
Gene expression involves the synthesis of gene products usually proteins and RNA. However, a certain product might not be needed at all or in small quantity. Gene regulation mechanism is the process that makes this happen. Gene regulation is the mechanism that acts to induce or repress the expression of a gene.
Gene regulation involves controlling the rate and manner of gene expression which is achieved through a set of regulatory proteins called transcription factors. Transcription factors bind to specific regulatory nucleotide sequences and help to turn "on or off" specific genes in the DNA.
Transcription factors can either be ACTIVATORS or REPRESSORS depending on whether they boost or inhibit gene expression. The binding sites for these regulatory proteins called TRANSCRIPTION factors are the regulatory nucleotide sequences on the DNA called enhancers and silencers.
Answer:
PHENOTYPE OF MOTHER -O BLOOD GROUP
GENOTYPE OF MOTHER -i/i
PHENOTYPE OF FATHER: AB BLOOD GROUP
GENOTYPE OF FATHER: A/B
THE OFFSPINGS WILL HAVE BLOOD GROUP EITHER A OR B .
THE PHENOTYPES OF OFFSPRINGS WILL BE EITHER A OR B .
THE GENOTYPES OF THE OFFSPRINGS WILL BE EITHER A/i FOR BLOOD GROUP A AND B/i FOR BLOOD GROUP B.
Explanation:
WHAT IS MULTIPLE ALLELES?
GENES WHICH SHOWS MORE THAN TWO ALLELIC FORM ARE CALLED MULTIPLE ALLELES. ABO BLOOD GROUPING IS CONTROLLED BY MULTIPLE ALLELES.
<u>CROSS</u>
MOTHER × FATHER
PHENOTYPES O × AB
GENOTYPES i/i × A/B
GAMETES i A B
F1 GENERATION A/i B/i
(GENOTYPES)
PHENOTYPES A AND B BLOOD GROUPS

Answers:
a. We will see DNA fragments with 145-200 bps (only one band)
b. The DNA sequence linked to histones will be protected from the action of DNase I, thereby this enzyme only can cut linker DNA (i.e., 55 bp fragments). In consequence, it is expected to observe a single band with a length of approximately 145 to 200 base pairs
Answer: evolution only leads to increase in complexity when complexity is beneficial to survival and reproduction.
