Question

19 multiple choice 2 points chromosome #3 would be classified as a(n) microsome allele sex chromosome autosome 20 multiple choice 2 points identify \c\ centromere sister chromatids gene q arm

Explanation:

1. Humans have 22 pairs of autosomes and 1 pair of sex - chromosomes. Chromosome #3 is one of the non - sex chromosomes, so it is an autosome. Microsomes are vesicle - like structures formed from the endoplasmic reticulum, alleles are alternative forms of a gene, and sex chromosomes are X and Y chromosomes.
2. The structure labeled "C" in the chromosome diagram is the q arm. The centromere is labeled as "A", sister chromatids are the two identical halves of the chromosome, and a gene is a segment of DNA, not the structure labeled "C".

Answer:

1. D. autosome
2. D. q arm
