Question 1

-cells must _____ for life to continue
-what molecule is essential for reproduction?
-this molecule is the only one capable of doing what
-it provides the _______ of the cell

Answer 1

-reproduce
-DNA
-duplicating itself
-blueprint

Question 2

How is DNA arrnaged in eukaryotic cells
-it’s called ________ in mitosis
-a chain of simple _______

Answer 2

-in chromatin
-chromosomes
-monomers/nucleotides

Question 3

-What is Loci
-what do genes determine
-in humans, chromosomes are found in _____, how many do we have?

Answer 3

-specific locations on chromosomes where genes occupy
-which protein molecules are produced, and therefore inherited traits
-pairs, we have 23 pairs (46 total)

Question 4

-What are the first 22 pairs of chromosomes known as in humans
-are these pairs found in Female, male, or both?
-Each individual pair is known as what? What does that mean?
-One chromosome is considered what of the other?
-how does inheriting work for pairs?

Answer 4

Autosomal chromosomes
-both
-a homologus pair (same shape and size, but not identical)
-a homologue
-in EACH pair, you get one chromosome from dad (paternal chromosome) and one from mom (maternal chromosome)

Question 5

-What do somatic cells contain
-What are gametes
-what does it mean for an organism to be polypoid

Answer 5

-pairs of homologus chromosomes and are said to be diploid (2n)
-sperm/egg cells containing unpaired chromosomes and considered to be Haploid (n)
-3 or more homologus chromosomes in each group

Question 6

What is the 23rd pair of chromosomes known as in humans?
-what do they determine
-how do they compare for females vs males?

Answer 6

-Sex chromosomes
-they determine genetic sex of the female/male
