Instructions: 1 Using the DNA sequence, make a complementary RNA strand from both the human and the cow. Write the RNA directly
Ksenya-84 [330]

Answer:

Please find the complete table attached as an image

Explanation:

This task is describing the processes of transcription and translation, which are the two processes involved in gene expression. The DNA of a human and cow is given in the table of the attached image and we're asked to transcribe into a complementary RNA, and subsequently translate into an amino acid using the CODON table (genetic code).

- Transcription is the process whereby DNA is used as a template for the synthesis of RNA based on complementary base pairing i.e. A-U, G-C, T-A etc.

- Translation is the process whereby RNA transcript is used to synthesize an amino acid sequence. The mRNA is read in a group of three nucleotides called CODON, where each of this codon specifies an amino acid.

The table has been completed and attached below. Note that in the amino acids row;

GLY means Glycine

ILE means Isoleucine

VAL means Valine

GLN means Glutamine

CYS means Cysteine

THR means Threonine

SER means Serine

PHE means Phenylalanine

ALA means Alanine

LEU means Leucine

If you could monitor the activity from the photoreceptors of rods and cones in the retina during a dream, would you expect these
loris [4]

The question is incomplete as it does not have the options which are:

- Yes, because people's eyes move during sleep, and this stimulates the rods and cones.

- No, because rods and cones only convert light energy into electrical signals.

- No, because rods and cones never produce electrical signals.

- Yes, because the rods and cones are reproducing images that are then sent to the brain.

Answer:

No, because rods and cones only convert light energy into electrical signals.

Explanation:

The rod and cone cells are the photoreceptor cells present on the retina of the eye which receives the physical stimulus in the form of light and then converts the light energy into the electrical energy which is sent to the brain.

When we dream, our remains closed and no light is able to enter the eye as a result of which the rods and cones do not send the signals to the brain.

Thus, the selected options are correct.
