Answer:
The recessive allele well be masked by the dominant allele in the heterozygous genotype
Answer:
Pigmentation of the skin results from the accumulation of melanin-containing melanosomes in the basal layer of the epidermis. Differences in skin pigmentation result both from the relative ratio of eumelanin (brown–black) to pheomelanin (yellow–red), as well as the number of melanosomes within melanocytes.
Explanation:
Those senses are sight, smell, hearing, taste, and touch. We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin. Our brain receives signals from each of these organs and interprets them to give us a sense of what's happening around us.
Answer:
The correct answer will be option- D.
Explanation:
Neurons are the cells which help in the transmission of the signals to and fro from the CNS and PNS to the body and vice versa. The structure of the neurons is divided into three main parts: the axon, dendrites and the cell body. The dendrites and axons are the extensions of the cell cytoplasm and together constitutes the neurites.
The dendrites are the extensions of the cytoplasm which receives the signals either from the cell surface as well as the from the post-synaptic neurons and further process the signals.
Thus, option- D is the correct answer.
14: Operons allow prokaryotes to replicate DNA at the appropriate time.
Operons are specific regions of genes that are linked to a singular process. They ensure that the expression of these genes does not go unchecked and only occurs when necessary. Two key examples of this in humans are the lac operon and trp operon.
15. The central dogma of molecular biology is:
DNA to RNA to Proteins
Protein Synthesis occurs in 3 steps.
First our DNA is translated into RNA. Next the RNA is sequenced into Amino Acids by reading the corresponding 3-Base Codons. These Amino Acid sequences form various protein structures.
