Answer:
the shape of protein is determined by its primary structure , amino acids . The sequence of amino acids in a protein is determined by the sequence of nucleotides
Assuming you mean to type:
"In humans, the allele for dimples (D) is dominant to
the allele for no dimples (d). at another gene locus, the allele for broad
eyebrows (B) is dominant to the allele for broad eyebrows (b)."
Man: Heterozygous for both genes means DdBb
Woman: no dimples, and heterozygous for slender eye-brows
means ddBb
Punnett Square
DB Db
dB db
dB DdBB DdBb ddBB
ddBb
dB DdBB DdBb ddBB ddBb
db DdBb Ddbb
ddBb ddbb
db DdBb Ddbb
ddBb ddbb
Interpretation: anywhere that has a capital letter has the
dominant trait.
Dimples+Broad eyebrows : 6 cases out of 16 (3/8=37.5%)
Dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
No dimples+Broad eyebrows: 6 cases out of 16 (3/8=37.5%)
No dimples+slender eyebrows: 2 cases out of 16 (1/8=12.5%)
Answer:
Changes in the genes DNA sequence can change proteins by altering their amino acid sequences, which may directly affect one's phenotype.
Explanation:
Answer: exocrine glands
Explanation: Exocrine gland secrete substances to an epithelial surface through a channel.
The sebaceous and sweat glands associated with the skin also secrete substance to skin surfaces via ducts/ channels and are classified as endocrine gland. There are two glands in the human body Exocrine gland and Endocrine gland.
Endocrine gland secrete substance into the bloodstream directly. Examples of exocrine glands are sweat, salivary, mammary, sebaceous, and mucous.
liver and pancreas are both exocrine and endocrine glands simultaneously.
As exocrine gland, the liver secrete bile and the pancrease secrete pancreatic juice into the gastrointestinal tract through channels. While as endocrine gland they secrete other substances directly into the bloodstream.
