Answer:

In babies born with congenital defects during the German measles rubella epidemic the specific cause of these birth defects was most likely the development of rubella virus infections in embryos.

Explanation:

Options for this question are:

1. The development of rubella virus infections in embryos. 

2. The failure of zygotes infected with rubella to develop

3. Mutations in the nerve cells of pregnant females at the time of the rubella epidemic .

4. An increase in the amount of time needed for healthy embryonic development.

Rubella is a viral infection caused by a virus of the genus Rubivirus, considered highly teratogenic during the phases of pregnancy where the embryo and the fetus are developing, that is, before 20 weeks of gestation.

The virus is transferred to the embryo or fetus by the mother's blood, acquiring the disease, which can cause abortions or visible malformations at birth, which is called Congenital Rubella Syndrome (CRB).

CRB is responsible for producing cardiovascular, renal, neurological malformations, loss of vision or hearing, problems that German children born during the epidemic probably had.

Snezhnost [94]

Not judging, but you probably would've gotten the answer if you posted in the Chemistry subject.

Answer:

C would be the incorrect statement.

Explanation:

When doing the calculations for finding the neutrons, you would get around 24 neutrons, since the mass is about 45 amu. 21 would be the number of protons.

Hope this helps :)

The immediate product of transcription is ________. The immediate product of transcription is ________. a protein an amino acid

AlekseyPX

Answer:

RNA

Explanation:

Transcription is the first process of protein synthesis and it involves copying the information encoded in the genetic material (DNA) to a RNA molecule. It involves making a complementary strand of mRNA from a DNA template.

The process of transcription commences when an enzyme called RNA polymerase binds to the promoter region of a gene on the DNA, signalling the unwinding of its double-stranded structure. The RNA polymerase then adds nucleotides to the growing RNA molecule, complementary to the ones it reads on the DNA. The RNA synthesized during transcription is called messenger RNA (mRNA).

The mRNA is then used as a template for amino acids synthesis during translation.
