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

a. a single, circular DNA chromosome found in the cytoplasm

because :

Prokaryotic cells may also contain extrachromosomal DNA, or DNA that is not part of the chromosome. This extrachromosomal DNA is found in plasmids, which are small, circular, double-stranded DNA molecules.

What are the different steps to cellular respiration?
Lina20 [59]

Answer:

Steps to cellular respiration:

1) In the first step of respiration, glycolysis occurs in which glucose molecule is converted into pyruvate molecule.

2) Krebs cycle is also called citric acidity cycle. In this cycle, hydrogen and electron are produced from the oxidation of pyruvate molecule and provides to electron transport chain.

3) Electrons carried by NADH + H and FADH2 are converted into oxygen through a series of electron carriers, and production of ATP occurs.
