Answer:
a) The enhancer site is a distal control site many nucleotides upstream from the promoter site, and activates the initiation complex of transcription.
Explanation:
Enhancers are the regulatory DNA sequences that are generally located quite away from the coding regions of a gene. These sequences are mostly present upstream of promoter sequences. Enhancers regulate the gene expression by stimulating the formation of an active transcription initiation complex and thereby, increase the rate of RNA synthesis. Enhancers also serve as the binding site for specific regulatory proteins. These proteins bound to the enhancers then activate transcription by interacting with the proteins bound to the promoters.
Answer:
It is homozygous at two gene loci.
Explanation:
An organism may be homozygous or heterozygous for a particular gene. The presence of two identical alleles of a gene in the genome of an organism makes it homozygous for the gene. On the other hand, the presence of two dissimilar alleles of a gene makes the organism heterozygous for the gene.
For instance, AA or aa are homozygous states since two copies of identical alleles (dominant and recessive respectively) are present. The genotype "Aa" is heterozygous since it has one dominant and one recessive allele for a particular gene.
The given genotype "AABbcc" is homozygous for "A" and "c" due to the presence of two copies of dominant and recessive alleles respectively. However, it is heterozygous for the second loci (Bb). Since the recessive allele is present in the homozygous state (cc), it will express itself.
