Answer:
True breeding
Explanation:
True breeding is a breeding in which parents produce the offspring which carry same phenotype.
The parents in true breeding are homozygous for every trait.
<u>True breeding occurs in the plants when the plants produce offspring of same variety only when self pollination takes place. </u>
<u>For example, if a plant has purple flowers will produce only seeds which will grow into plants which have purple flowers.</u>
Your spinal cord is part of your central nervous system. True or False
Answer: True
Answer: b)Steroid hormone receptors are located within the cytoplasm of a cell.
Explanation: Steroid hormones are the element present in the body that provides management in inflammation, metabolism, illness resistant , improves immune function etc. They are obtained from the cholesterol. The particular receptors of the steroid hormone is located at the cytoplasm.
Other options are incorrect because steroid hormone binds the certain receptors only not neurotransmitters .It does not have domain of 20 trans-membrane and is bound to ligand for activation.Thus , the correct option is option(b).
Answer: B. by toxic chemicals (in smoke) or radiation that can damage the DNA in cells.
Explanation:
The carcinogens presents in cigerates covalently bind to DNA and form DNA adducts which results into miscoding (e.g., insertion of the wrong base) during replication of DNA and this genetic mutation causes uncontrolled cellular growth which causes cancer.
Ionising radiation including X-rays, radioactive particles, and gamma rays,can cause cancer by damaging DNA. high-energy radiation damages DNA and cause genetic mutation same as cigerates and causes cancer.
Both toxic chemicals (in smoke) or radiation damages DNA inthe cells which leads to cancer.
Hence, the correct option is B.
Answer:
The correct answer will be - Primary structure
Explanation:
Proteins are one of the biomolecules formed by the process of translation.
Depending on the function they attain many structures like primary, secondary, tertiary and Quaternary structure.
The primary structure is the simplest structure formed by binding the amino acids via peptide bonds in linear order. This simplest structure is formed by the process of translation in which tRNA brings specific amino acids to the nascent peptide.
Thus, Primary structure is the correct answer.
