Infectious agents are those that corrupt and prey on an organism or a host. This is sometimes called parasitism when a foreign organism consumes a host by preying on its nutrients and food. Hence, we are uncertain in Anna's case because there is no clear description of her symptoms.
Answer:
the cell was dicovered in 1665
The right answer is D. 1 pair of sex chromosomes and 22 pairs of autosomal chromosomes are pictured.
EXPLANATION:
A False, because A karyotype displays all of an individual’s DNA (deoxyribonucleic acid) and not RNA (ribonucleic acid)
B False, because the karyotype display all types of chromosomes (autosomic (22) and sexual (1))
C False too, because the human karyotype contains 23 chromosome pairs (22 autosomes and 1 gonosome (X/Y chromosome))
Answer:
This question lacks options, the options are as follows:
A. 3’ ATA GTG CCC AAC GGT 5’
B. 3’ TAT CAA GGG TTG CCA 5’
C. 3’ TAT CAC GGG TTG CCA 5’
D. 3’ TAT CAC GGG TTG CCT 5’
The answer is C
Explanation:
DNA replication is the process by which a DNA molecule makes a copy of itself i.e. duplicated. In this process, the double-stranded DNA molecule splits into two single strands, which each serves as template for the synthesis of another strand. The new strand is synthesized using the COMPLEMENTARY BASE PAIRING RULE.
Complementary base pairing rule states that an Adenine base will always hydrogen bond with a Thymine base while Guanine base will always hydrogen bond with Cytosine base i.e. A-T, G-C. Hence, given the original strand of DNA in this question, the complementary strand will have the following sequence: 3’ TAT CAC GGG TTG CCA 5’
