Answer:
The trait is heterozygous.
Explanation:
Heterozygous: "Having two different alleles of a particular gene or genes."
A heterozygous genotype looks like: Rr. The capital R is a dominant allele, and the lowercase r is a recessive allele. These two alleles are not the same (not two dominant alleles or two recessive alleles) meaning that the trait is a heterozygous trait.
The opposite of a heterozygous trait is a homozygous trait, in which both alleles are the same (both dominant or both recessive) and can look like RR or rr (genotype-wise).
Answer:
C. 3, 2, 1
Explanation:
During a single PCR cycle, the very first step is the heat separation of the double stranded DNA. Primer binds only single stranded DNA/RNA because it has complimentary bases which match single strand of DNA/RNA that is why it is necessary to unwind both the strands of DNA by providing temperature.
As soon as the DNA strands have separated by increasing the temperature to ~ 95 °C, in the next step the primer binds the portion of DNA which is complimentary to the bases of the primer. In order for primer to bind DNA, the temperature is lowered to ~ 72 °C and the process is called as annealing.
Once primer has bound to the DNA, the next step is polymerization i.e. nucleotides which are the monomer units of DNA are added one by one with the help of enzyme named as Taq polymerase. This is how the strand extends ahead of primer and exact copies of the given DNA are produced.
Note: PCR may be considered as in vitro DNA synthesis or replication.
Explanation:
Because it needs a place to hide and place it eggs.
Hey all I gotta say is look up the definition and you’ll find the answers it’s not that complicated
