Answer:
The primary defined divisions of time are eons, in sequence the Hadean, the Archean, the Proterozoic and the Phanerozoic.
Explanation:
The correct answer is A. Homologous chromosomes with heterozygous alleles.
If the alleles of genes are different then the scientist is observing for homologous chromosomes with heterozygous alleles.
In each homologous pair there is one chromosome which comes from maternal chromosome and the other one from paternal chromosome.
Homologous chromosomes are not identical but they are similar. Alleles for each homologous chromosome is not same but genes are the same.
Answer:
If we could pick more than 1 i would pick b) and c)
But if only 1 then pick d) because captive breeding would be one but not the most efficient
Explanation:
Answer:
To allow transcription enzymes to access the DNA strand
Explanation:
The DNA double helix is made up of two complementary strands wound around each other, and tightly packaged as chromosomes.
DNA and RNA polymerases promote either DNA or RNA synthesis by attaching free nucleases to parent strands (a), which are then unwound and isolated by helicases (b). DNApolys synthesize DNA in a 5'-3 ' direction; owing to its restricted flow, there are only two types of replication: continuous from the point of differentiation of chromosomes, fork, and discontinuous from the fork.
Yeah the answer is human error lots of people have been studying this.
