The number of copies of a gene is called

6. in the rudimentary immune system of bacteria, a record of fragments of DNA from previous viral infections is contained within what part of the bacterial chromosome?     chromosomal DNA     spacer DNA     palindromic DNA     AOTA     NOTA

3 and/or 4 please

10. Alleles are   A. Alternate forms of genes   B. Linked genes   C. Chromosomes that have crossed over D. Homologous chromosomes

6. You perform a high throughput DNA sequencing reaction on chromosome number 1 from a newly discovered blue mold that grows on the bottom of the ocean. Below are the contig fragments. Put the fragments in order and determine the sequence of the entire chromosome by looking for overlapping sequences on the fragment ends. Fragment 1 TGTACCGTACGAC Fragment 2 GGCTATTTCGCCG Fragment 3 CGACTACTACTAC Fragment 4 CGCCGCGCATGTA a) Order of fragments first to last that creates the full chromosome sequence b) Sequence of the complete chromosome

24.  DNA replication begins at the start of mitosis and meiosis. Group of answer choices True False

6.

16. differential gene action or selective expression of genes confers to the phenotype of the cell true or false

1. Identify the CORRECT statement from the following options: DNA is named for the fact that it occurs as a DOUBLE helix Human genes come as identical pairs that we refer to as SISTER CHROMATIDS It is not accurate to refer to a gene as dominant or recessive - but ALLELES are The CRITICAL PERIOD refers to the time when a woman can get pregnant We refer to our somatic cells as DIPLOID because they have one copy of each gene
