Explanation / Answer

29.b.

mitosis occurs both in Germany cells and somatic cells.

30.b. false

Haplod cells 23 and diploid cells have 46 chromosomes.

Diploid cells contain two complete sets (2n) of chromosomes.

Haploid cells have half the number of chromosomes (n) as diploid - i.e. a haploid cell contains only one complete set of chromosomes.

31.a true

a Punnett square is usedto show the possible combinations of alleles an offspring might inherit from two parents.

32.a true

a recessive trait within an organism, is present, but is not expressed.

33.a .true

The genetic code consists of 64 triplets of nucleotides. These triplets are called codons.With three exceptions, each codon encodes for one of the 20 amino acids used in the synthesis of proteins.

34.b .True

One codon, AUG, is a “start” signal to kick off translation (it also specifies the amino acid methionine)

Diploid cells contain two complete sets (2n) of chromosomes.

Haploid cells have half the number of chromosomes (n) as diploid - i.e. a haploid cell contains only one complete set of chromosomes.
