Acid-fast bacteria are gram-positive, but in addition to peptidoglycan, the outer membrane or envelope of the acid-fast cell wall of contains large amounts of glycolipids, especially mycolic acids that in the genus Mycobacterium, make up approximately 60% of the acid-fast cell wall

Answer:
Parental genotypes: RrBb, RRBB
Offspring phenotype: Running and black hair
Explanation:
Given, Running (R) is dominant over waltzing (r)
Black hair (B) is dominant over brown hair (b)
Parent 1: Heterozygous running, heterozygous black = RrBb
Parent 2: Homozygous running, homozygous black = RRBB
When they mate ( RrBb X RRBB ) :
Gametes produced by RrBb = RB, Rb, rB, rb
Gametes produced by RRBB = RB
Offspring:
RB Rb rB rb
RB RRBB RRBb RrBB RrBb
All offspring mice will be running mice and will have black hair because all the four types of genotype at least have one dominant allele for both the genes.
Helicase is the name of the specialized enzyme that unzips the bonds between bases.
By severing the hydrogen bonds between base pairs and unwinding the DNA molecule's two strands, an enzyme known as Helicase aids in unzipping the molecule. It binds to and dissolves the hydrogen bonds connecting the bases on the DNA strands. These hydrogen bonds continue to be broken as the helicase travels along the DNA molecule, separating the two polynucleotide chains.
Primase, a different enzyme, momentarily binds to each strand when the helicase separates them in order to build a foundation upon which replication can start.
