humans and fish evolved from insects
B.
different species synthesize the same proteins
C.
insects, fish, and humans express the same genes
D.
different species share components of the genetic code
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code
Explanation:
Evaluating the other options given
A.humans and fish evolved from insects-This option is incorrect as human and fish did not have a common ancestors.
B.different species synthesize the same proteins:No this statement also is not the correct option
C.insects, fish, and humans express the same genes-The expressed genes cannot be same for different species
Hence the correct answer is
The codons that code for alanine in a potato beetle are the same as those that code for alanine in mackerel and humans. This evidence best supports the idea that -(D) different species share components of the genetic code(As the genetic code is said to be universal
Answer:
first- class proteins comes from eggs , meat , fish and dairy products while non - animals related foods ,like vegetables and fruits, provide second - class proteins . first - class proteins contain a necessary amount of these important amino acids , but second - class proteins only contains some of them.
Explanation:
b. nucleoid region
c. nucleus
d. ribosomes
Option B, Nucleoid region
The DNA of a bacterial cell is found in its nucleoid region, not in a nucleus, capsule, or ribosomes. The nucleoid is an area in the bacterial cell where the genetic material is located.
The DNA of bacterial cells is found in its nucleoid region. Bacteria do not have a nucleus, a characteristic feature of eukaryotic cells, and their genetic material is instead located in a region of the cell called the nucleoid. The nucleoid is not bound by a membrane, unlike the nucleus in a eukaryotic cell. Therefore, options a (capsule), c (nucleus), and d (ribosomes) are not correct. There are various other parts of a bacterial cell. For example, the capsule provides protection to the bacterial cell, while ribosomes are responsible for protein synthesis.
