1. (B) The answer is LIGASE.
Ligase is that enzyme in DNA repication which seals the gaps
between the nucleotide bases after the polymerization.
2. (D) the answer is dNTPs, primers, template DNA, DNA
polymerase
Because, during the beginning of the process of DNA replication,
dNTPs are required to attach to the nucleotide chain. Primers are
required for the initiating the the chsin of nucleotides. Template
DNA is needed as the template on which the new strand will be
coded. DNA polymerase is needed as the enzyme which polymerize the
new nucleotide chains by attaching new dNTPs to the chain.
3. (D) The answer is Trisomy.
It i sthe type of poysomy, where there are three copies of a
particular chromosome. It is a type of aneuploidy. th epicture
provided here has three instances of the chromosomes, so the answer
is Trisomy.
4. (C) The answer is Very Low.
The presence of tryptophan blocks the expresson of the Tryptophan
Operon.
5. (C) Allows expression of the structural genes within the tp operon to occur when tryptophan is not present within the bacterial cell.

This specific blood type is an example of: A) multiple alleles B) epistasis C) codominance D) partial dominance Imagine the gene encoding the lac repressor was mutated so that lactose (more technically allolactose) no longer bound to the repressor. However, the lac repressor was still capable of binding DNA at the operator sequence....
Yet, all the cells in your body contain the same genes (and same alleles). The difference across cell types is that genes get selectively expressed (turned on or off) based on the proteins needed for cellular function given their environment.

Muscle cells do not have the gene for keratin and...
