Answer:
The mother must be heterozygous.
Explanation:
t=Tay-Sachs trait
T=Normal trait
Parent genotype combinations:
Tt x Tt
Possible genotypes:
<u> | T | t </u>
<u> T </u><u>| TT | Tt </u>
<u> t </u><u>| Tt | tt </u>
Since it is a recessive trait there must be 2 of the recessive alleles for the trait to show. This means neither of the parents can be totally normal(TT).
Since both parents are considered normal the both must be heterozygous to be able to produce an child with Tay-Sachs.
Answer: plants use carbon dioxide
Explanation:
The plasmid is an extra-chromosomal small circular and double stranded DNA molecule present in the prokaryotic cells. These are often found in some eukaryotic cells also. The plasmid DNA carries the genes which are responsible for the antibiotic resistance for the prokaryotic cells.
Answer:
The three processes from left to right are:
<u>Replication</u> DNA <u>Trancription</u> RNA <u>Translation</u> Protein
Explanation:
The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:
- DNA Replication
- Transcription
- Translation
DNA Replication:
DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.
Transcription:
Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.
Translation:
Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.
