Which scientists was the first to suggest that growth of cancerous cells was a result of abnormal chromosomes?
maks197457 [2]

Answer:

The correct answers are B and C. Walter Sutton and Theodor Boveri were the first to suggest that growth of cancerous cells was a result of abnormal chromosomes.

Explanation:

The chromosomal theory of inheritance is a scientific theory that relates chromosomes with the transmission of inheritable characters. It is also called the chromosomal theory of Sutton and Boveri in honor of the two people who independently developed it in 1902, Theodor Boveri and Walter Sutton. This theory states that the alleles, the Mendelian genetic factors, are on chromosomes.

Theodor Boveri and Walter Sutton independently developed the chromosome theory in 1902, Boveri, studying embryonic development in sea urchin and Sutton in this work on meiosis in grasshopper.

Sutton and Boveri's proposition in 1902 that chromosomes are the factors of Mendelian inheritance was controversial until its demonstration in 1915 by the work of Thomas Hunt Morgan in the Drosophila melanogaster fly.

tester [92]

Answer:

Each species has a specific identifying number of chromosomes. For example, a cat, <em>Felis catus</em>, has 38 chromosomes, while corn, <em>Zea mays</em>, has 20 chromosomes each chromosome carries specific genes that are unique to that chromosome.

Explanation:

Chromosomes vary in shape and number among living beings. For example, the bacterial chromosome is a unique circular molecule, while human beings have 46 lineal chromosomes arranged in pairs (23 pairs). The total number of chromosomes is specific to each species, and it is denoted as the "chromosomic dotation" of the species.

Genes are the hereditable units that transmit the information needed to specify traits, from parents to offspring, generation to generation. Genes are arranged in sequence in the chromosomes. A chromosome might contain hundreds of thousands of genes.

Genes vary in size and shape.  They are composed of pairs of bases, and these sequences also vary in number, producing genes of different lengths. In general, genes code for proteins. Proteins create the organism tissues and perform or carry out specific functions in the organisms, controlling almost all processes and chemical reactions.

Each chromosome carries <u>specific</u> genes that code for <u>specific </u>proteins that have <u>specific</u> functions in the organisms. Each chromosome carries information to synthesize different proteins needed to accomplish a certain function. But <u>not all chromosomes carry the same gene sequences</u>. Only homologous chromosomes carry information for the same trait, but even this information is not necessarily the same. They might have the same gene but different alleles.
