A chromosome contains many different gene regions that are transcribed into different ________.
a. proteins | c.
|
b. polypeptides | d.
|
Introduction:
There is a variety of living organisms that are present in the environment. Most of the organisms contain a nucleus in which the genetic material is stored. The genetic material plays a very crucial role in the functions of the organism. A chromosome is a part of genetic material that contains genes. It is present in the nucleus.
Answer to Problem 1SA
Correct answer:
The regions of a chromosome that contains genes are transcribed into
Explanation of Solution
Reason for correct answer:
Option c. is given as “
Reason for incorrect answer:
Option a. is given as, “proteins.”
The process of producing proteins from the information present in the genes is called translation. However, transcription does not include the conversion of information present in the genes into proteins. Hence, option a. is incorrect.
Option b. is given as, “polypeptides.”
The units that join amino acids together to form protein molecules are called polypeptides. This type of conversion is not observed during transcription. However, the process of formation of polypeptides from the information present in the genes is called translation and not transcription. Hence, option b. is incorrect.
Option d. is given as, “
A nucleotide contains three constituents that are “pentose sugar (deoxyribose), nitrogenous bases and a phosphate group.” Many nucleotides join together to form a polymer called as nucleic acid.
Hence, the options a., b., and d. are incorrect.
The genes present on the chromosomes are transcribed into
